AIRBAG COIL SPRING FAILS
MORE THAN JUST A TOTAL FAILURE OF THE HORN AND STEERING
Horn, steering wheel buttons, airbag warning message – all of these
can fail if the airbag coil spring fails. It connects the rigid steering
column to the movable steering wheel and transmits not only the
airbag's trigger impulse, but also numerous control signals from the
horn, radio, cruise control and assistance functions.
This is often caused by material fatigue or
mechanical damage to the fine conductive
foil inside – often due to wear and tear,
incorrect installation or sudden stress. If a
conductor track breaks, the electrical connections
between the steering wheel and
the control unit fail – with possible warning
messages appearing on the display.
The consequences: In addition to the
failure of safety-related functions such as
airbag signalling, the horn will also stop
working. Steering wheel buttons no longer
respond. In rare cases, workshops report
noises or annoying scratching sounds when
steering.
Nevertheless: It’s more than just annoying
– in serious cases, it can be life-threatening.
The coil spring is a safety-related component
that plays a role in the airbag deployment
system. As such, if it is faulty, it must be
replaced – not repaired.
VEMO solutions in original equipment
quality – smart, secure and reliable
VEMO offers tailor-made, tested replacement
coil springs with OE quality that are precisely
matched to the model and steering column.
They ensure maximum operational reliability
and make repairs easier for you: no reworking,
no sources of error and no returns.
During installation, ensure that the ignition
is switched off, the steering wheel and
wheels are in the centre position, and the
existing coil spring is completely replaced –
do not reuse it. Be careful not to damage the
fixings and position the retaining elements
precisely.

Causes of a faulty
coil spring
These causes are most often responsible
for airbag coil spring failures:
Wear
Constant steering puts mechanical strain
on the coil spring. Over time, the conductor
tracks wear out, making interruptions
inevitable.
Corrosion
Moisture, salt and similar substances
attack the contacts. The result: Poor
conductivity – and in the worst case,
total failure of the airbag.
Vibrations and shocks
Uneven roads and hard knocks put
a strain on the sensitive mechanics.
This can loosen or even destroy the coil
spring.
Assembly errors
Improper installation? Devastating! Even
minor errors during installation can lead
to serious malfunctions.
Extreme temperatures
Hot, cold, hot again: temperature
fluctuations cause plastic parts to age
and can lead to tension or cracks in the
coil spring.
Symptoms of a faulty
coil spring
The symptoms of a faulty coil spring are
not just annoying, they can also be
extremely dangerous – especially if you
ignore them or take them lightly. That’s
why you should watch out for these
warning signs:
Is the airbag warning light permanently
on?
This is no coincidence, as it could mean
that the airbag will not deploy in an
emergency.
Signal horn not working?
It sounds harmless, but it is often a clear
sign of a problem in the slip ring.
Total failure at the wheel?
If the steering wheel buttons, paddle
shifters or cruise control no longer
respond, this is usually due to a loss of
signal caused by a faulty coil spring.
Cracking noises when steering?
Such mechanical noises may indicate
internal damage to the coil spring.
Does the steering wheel feel stiff
or uneven?
In some cases, a damaged coil spring can
also affect steering feel. This should not
be taken lightly.
With the VEMO coil spring, you are not only
offering your customers a spare part, but
also a measure of safety. A sustainable
solution you can really rely on.

works!

HEAVY
UNDER LOAD
WHY ELECTRIC CARS PLACE HIGH DEMANDS ON SUSPENSION
Anyone who works on electric vehicles quickly notices that the chassis components are
subject to completely different stresses than those affecting a conventional combustion
engine. This is particularly evident in the suspension – not only does it carry more weight,
but it also has to cope with completely different force profiles.
The biggest issue is the high vehicle weight.
In most models, the battery is located in the
underbody and adds several hundred kilograms
of weight – permanently. This means
that shock absorbers, springs, strut bearings
and suspension components have to
support significantly more mass, resulting in
greater wear and tear and increased material
stress. A classic case for preventive maintenance
– and high-quality components.
Added to this is the change in weight
distribution. The flat battery base and the
new axle load distribution result in completely
different requirements for the front
and rear axles. The spring and shock
absorption characteristics must be precisely
matched to the model – otherwise, not only
will driving comfort suffer, but also durability.
An additional stress factor is the directly
adjacent torque. While a combustion engine
only develops its power as the revs increase,
electric vehicles deliver their full power right
from the start. These forces place enormous
strain on the wheel suspension and suspension,
especially when starting or accelerating
– particularly in heavy SUVs or sporty
models with four-wheel drive.
The situation also changes when braking:
Recuperation ensures that deceleration is
achieved via the electric motor rather than the
brake system. This has a direct effect on the
chassis – partly jerky, partly asymmetrical.
The load on bearings, shock absorbers and
axle guides increases further.
One thing is clear: the chassis of electric
cars operate under significantly harsher conditions
than we are used to seeing. Greater
weight, altered dynamics and aggressive
load changes demand precise tuning and
particularly durable components. That’s why
you mustn’t compromise on shock absorbers,
air suspension or bearings – and when it
comes to spare parts, it is best to rely on the
tested quality of VEMO and VAICO.
Recommendations for
workshop practice
When servicing the chassis of electric
vehicles, it is particularly important to
bear the following points in mind to
ensure long-term safety and functionality:
• Manufacturer's specifications
must be strictly observed
• Only use tested quality parts
(e.g. VAICO/VEMO)
• Always include wheel
alignment and calibration in
your planning
• High-voltage work may only
be carried out by trained staff
• Tightening torques must be
strictly adhered to

What you absolutely must remember when servicing the
chassis of electric vehicles
High-voltage safety is the top priority
Before working on the chassis, always:
• Disconnect vehicle from its power supply
• Perform high-voltage clearance (especially when working near the battery tunnel or on
landing gear)
• Only trained personnel (e.g. Level 2S) may work on HV-sensitive areas.
Without training, there is a risk of death and legal liability!
Wheel alignment is mandatory after every service
• After replacing springs, shock absorbers or bearings, precise wheel alignment with
calibration is mandatory
• Especially for vehicles with lane departure warning or steering assist systems: Without correct
calibration, there is a risk of malfunctions, false warnings and inaccurate driving behaviour
Don’t forget sensors and chassis control
Many electric vehicles have electronic level sensors and damping control
(often linked to recuperation management)
Once replaced: Check sensors for proper functioning and calibrate if necessary!
CONSEQUENCES OF ERRORS:
• Height deviations (esp. for air suspension)
• Error messages in the instrument cluster
• Unstable or unbalanced handling

Correct installation: Torque values, sequence, quality
ALWAYS:
• Adhere to manufacturer torque specifications
• Carry out the assembly in the specified order
COMMON MISTAKES CAUSED BY INCORRECT TIGHTENING:
• Creaking noises
• Material tension
• Component failure or premature wear
Always work in eights – no half measures
Always replace safety-related parts such as springs, shock absorbers or wishbones in pairs
on one axle. This way, you’ll avoid:
• Uneven suspension travel
• Tilting
• Tight bearings, uneven tyre wear

TIME BOMB?
TIMING BELT IN OIL BATH ON THE FORD 1.0 ECOBOOST
The oil-lubricated timing belt in Ford's 1.0
EcoBoost engine was considered innovative
when it was introduced: more durable,
quieter and more efficient. In practice,
however, the opposite is true. Many
workshops report premature wear, rubber
particles in the oil circuit and, in the worst
case, major engine damage.
The cause is the chemical reaction of modern
oil additives with the rubber compound
of the belt.
MORE ABOUT
BELT DRIVES
AND CO.
The result: Material fatigue, loose particles,
clogged oil channels and damaged pumps.
Excessively long replacement intervals are
particularly critical – damage often occurs
after just 80,000 kilometres. Symptoms
such as loss of performance or warning
lights are easily overlooked, leaving workshops
faced with time-consuming fault analysis
and disgruntled customers.
The solution: The VAICO timing belt kit
The specially developed VAICO timing belt
kit for 1.0 EcoBoost engines is resistant to
aggressive oil additives and significantly
more durable than many original parts. As
an EXPERT KIT+, it comes complete with
timing belt, tensioner and idler pulleys, seals
and – depending on the application – all
screw types.
All parts are manufactured to OE quality and
optimally matched to each other – for safe,
efficient repairs.
Prevention rather than engine failure
Instead of relying on manufacturer
specifications of 180,000 to 240,000
kilometres, many workshops recommend
replacing the timing belt as early as
80,000 kilometres.
Preventive repairs are particularly worthwhile
for frequently used vehicles such as
the Fiesta, Focus or Transit Courier: They
protect the engine and oil circuit – and save
workshops from unnecessary complaints
and costly returns.
With the VAICO timing belt kit, workshops
guarantee the right solution for sustainable
repairs and satisfied customers.

VAICO timing belt kits: Quality that protects
VAICO stands for OE-compliant repair solutions that you can feel in the workshop – and
recommend to your customers with a clear conscience. Our timing belt kits are precisely
tailored to the specific requirements of oil-lubricated systems.
Durability thanks to oil-resistant material
The specially developed rubber compound is permanently resistant to modern engine oil
additives – and provides reliable protection against premature belt ageing, which often
occurs with first-generation OE parts.
EXPERT KITS+: Everything in one box
The set includes: timing belt, tensioner and idler pulleys, seals and, depending on the
model, water pump, screws and even the appropriate oil. Perfectly matched for safe,
time-saving repairs without any nasty surprises.
Early replacement instead of costly consequential damage
Do not rely on long replacement intervals – preventive replacement with VAICO provides
reliable protection against major engine damage caused by worn BIO belts.
Less abrasion, more protection
Our material mix minimises abrasion in the oil bath, thereby reducing contamination,
blockages and oil pump wear – for maximum service life and a clean oil circuit.

WHEN SAFETY GOES
INTO A SPIN
FAULTY ACCELERATION SENSORS: A SAFETY RISK
A vehicle suddenly becomes unstable when taking a bend, the ESP does not intervene –
the ABS/ESP warning light illuminates in the cockpit. Sound familiar? In the workshop, it
quickly becomes clear that the fault lies in the driving dynamics system, or more precisely
in the longitudinal or lateral acceleration sensors.
These small but crucial vehicle sensors provide the data basis for systems such as ESP,
ABS and traction control. If a sensor fails, a routine journey becomes an incalculable
safety risk.
Modern vehicles feature numerous
assistance systems that work unnoticed in
the background to ensure safety and
stability. In order for these systems – in
particular the Electronic Stability
Programme (ESP) – to function correctly,
they rely on accurate information. One of the
most important sources of data here is the
acceleration sensors. They detect how the
vehicle is moving in the longitudinal and
lateral directions and transmit this
information to the control unit in real time. If
there are disruptions or faulty signals, this
has an immediate impact on driving
behaviour – as well as safety.
A faulty accelerometer is often not
immediately apparent. The ESP or ABS light
in the cockpit may occasionally illuminate,
and the vehicle may react unusually or
unsteadily when taking a bend or braking.
The symptoms are diffuse and cannot
always be directly attributed to a specific
component, which makes it difficult to
diagnose the fault. Often, the sensor does
not fail completely immediately, but instead
provides inaccurate or sporadically
intermittent values over a longer period of
time. Particularly in the case of electronic
stability programmes, which react with
millisecond precision, this is enough to
delay or prevent intervention in an
emergency.
The technology – what do longitudinal
and lateral acceleration sensors do?
These acceleration sensors detect the vehicle’s movements along two axes:
Longitudinal axis (acceleration/braking behaviour)
Transverse axis (cornering/drifting)
The measurement data is transmitted to the control unit in real time and is essential
for the proper functioning of the electronic stability control (ESC), ABS, traction control
and other driver assistance systems. They ensure that the vehicle is stable and
safe even in critical moments.
The causes of faulty sensors are manifold.
In addition to age-related wear and tear,
external influences such as extreme
temperature fluctuations, vibrations,
moisture, or corrosion also play a role.
Solder joints can break, housings can be
damaged, circuit boards can crack – and
suddenly functionality is impaired.
As a workshop, you should specifically
include the acceleration sensors in the
diagnosis if the corresponding symptoms or
warning messages occur. Modern testing

The following symptoms may indicate

Longitudinal and transverse acceleration
sensors are components that are subject
to extremely high stresses. Common
causes of faults include:

short circuits)
Extreme temperatures or humidity
Material fatigue
Replacing parts in good time is crucial
to increasing safety and satisfying
customers.
equipment usually provides clear indications
as to which sensor is affected – often
a distinction must be made between
transverse and longitudinal acceleration
sensors. Once replaced, many vehicle
models require precise calibration in order to
communicate the new reference values to the
ESP system. If this step is skipped, the
system may continue to operate using
incorrect data.
When it comes to spare parts, focus on
quality, especially for sensitive components
such as acceleration sensors. VEMO offers
sensors in tested OE manufacturer quality,
designed for maximum reliability and
precision fit. This reduces subsequent
complaints and ensures that the stability
systems in the vehicle are working properly

Identifying parts takes time and often increases stress levels. You rarely have any certainty –
is everything really there and can the job be completed smoothly?
More than just a finder – a real innovative
leap for workshops
VIEROL is setting new standards in parts
identification by introducing the EXPERT KIT
FINDER. The smart AI technology, the userfriendly
chat function, the vehicle licence
scanner and continuous further development
in collaboration with workshops make
the search for the right repair kit easier and
more efficient than ever before. This results
in less time searching and more time on the
essentials – the repair.
‘Workshops can find the right EXPERT KITS+
from VEMO, VAICO and ACKOJA in just a few
clicks, without entering any vehicle data or
with the help of the chat bot,’ adds Michael
Krone, Head of IT and Logistics at VIEROL.
‘The user-friendliness and speed of the system
is unparalleled,’ adds the IT specialist
and driver responsible for realising the
EXPERT KIT FINDER.
The responsive design of the EXPERT KIT FINDER ensures optimum use on all terminals –
from your smartphone to your desktop.

AI INSTEAD OF KILOMETRES
HOW PIRELLI USES VIRTUAL TEST TRACKS
Tyres are high-tech products – and their
development is no longer pure workshop
work. With its Virtual Development Centre
(VDC) in Breuberg, Pirelli is focusing on
digital twins, simulations and artificial
intelligence. The aim is to develop tyres
faster, more precisely and more sustainably.
Digital twins instead of endless prototypes
The VDC not only simulates tyres, but also
entire vehicle models. On this basis, driving situations
can be realistically simulated – long
before a physical prototype is built. The simulator
recreates laser-measured routes, authentic
driving dynamics and even steering forces and
sound.
The advantage for vehicle manufacturers and
workshops: tyres are optimally tailored to the
respective model at an early stage of development.
This precision is particularly crucial for
electric vehicles, which place special demands
on load capacity, torque and rolling resistance.
AI makes the difference
Artificial intelligence is now in daily use and
around the clock. The possibilities of neural
networks are showing ever greater potential
when it comes to evaluating huge amounts of
data. This allows reliable predictions to be
made about how a tyre will behave in a wide

WHY THE CORRECT TYRE PRESSURE IS SO CRUCIAL
CHRISTIAN GRIMM
Racing driver & driving instructor
VEMO Porsche driver Christian Grimm on
the inconspicuous but crucial detail in the
GT3: Tyre pressure.
Christian, why does everyone in GT3
KLEINMOTOREN 1. constantly talk about tyre pressure?
SMALL-POWER MOTORS
Because it determines everything. If the
15601 | 23001 | 23002 | 27101
pressure isn’t right, you lose grip – and
without grip, you can’t do fast laps. Too high
or too low also means that the car becomes
unstable. So, it’s not just about speed, it’s
also about safety.

What distinguishes your racing tyres
2. from our road tyres?
A GT3 tyre is constructed differently
from the ground up. It has a much softer
rubber compound that reaches operating
temperature extremely quickly, delivering
maximum grip – but it doesn’t last nearly
as long as a road tyre. The carcass is also
stiffer so that the tyre can withstand
enormous lateral and longitudinal
forces on the race track. Tyre pressure
is completely different, too: We let air
out before driving because the tyre heats
up significantly during use and the
pressure automatically increases.
A road tyre never gets that hot in everyday
use, so its pressure remains relatively
constant.
How does incorrect pressure manifest
itself? 3.
The temperature determines the grip. If the
tyre is overloaded, it starts to ‘grain’ – i.e.
peel. This causes rubber fragments to form,
which impair the contact surface. The result:
less grip and slower lap times.

EXHAUST GAS RECIRCULATION

11801
How do you ensure that the
pressure is correct?
Before every journey, we measure when
cold, adjust and observe how the pressure
rises as the temperature increases. After a
few laps, the optimum window is reached –
and from then on, the tyre works perfectly.
LUFTFEDERUNG
AIR SUSPENSION
5.
19401 | 19402 | 19403
And what do the regulations
say about this?
There are fixed minimum pressures that
must be maintained. This protects both the
tyre and the driver. However, you have to
react at lightning speed when the weather
changes: a rain tyre on a dry track or a slick
tyre in the rain – neither is acceptable.
Quality brand of VIEROL AG · Germany
Your personal tip?
6. Ultimately, the tyre is the only
component that makes contact with the
road – whether that’s in a GT3 racing car or
an everyday car. Keeping an eye on your tyre
pressure makes driving safer, protects your
equipment and gets more out of your
vehicle. In racing, a few tenths more or less
can mean the difference between victory
and defeat – and in road traffic, the
difference between control and risk.

JENS REIMERS

HOW TO AVOID A COSTLY GEARBOX FAILURE
In many Mercedes 4MATIC models with 7-speed automatic transmission (7G-Tronic or
7G-Tronic Plus), damage to the transfer gearbox between the drive shaft and front axle
differential often results in total economic loss. For cost reasons or due to missing parts,
Mercedes-Benz only replaces the entire gearbox, which involves extremely high costs and
long workshop times.
A common scenario: The rubber sleeve on
the drive shaft tears, allowing water or road
salt to penetrate and cause corrosion. Over
time, play develops in the joint and the
cardan shaft hits against the gearbox, which
is accompanied by knocking noises. Without
intervention, there is ultimately a risk of
cardan shaft breakage or bearing damage.
Worn bearings inside can also damage
gear plates, rendering the entire gearbox
unusable.
Your solution: the VAICO EXPERT KIT+
VAICO has developed an economical
alternative for this vehicle configuration.
The VAICO EXPERT KIT+ for targeted repair
of the transfer gearbox in 7G-Tronic &
4MATIC. Instead of installing a complete
replacement gearbox, you only replace the
necessary components, thereby saving
a lot of money.
The kit has a modular design. You can
choose between the complete kit including
shaft and the BEK version ‘without shaft’ if
only the bearings are affected. All parts are
of original equipment manufacturer quality,
are precisely matched to each other and can
be installed immediately – without missing
components or long delivery times.

AI MEETS THE WORKSHOP:
PREMIÈRE FOR THE VIEROL MOBILITY TALK
How is artificial intelligence changing
everyday life in the workshop? This
question formed the focus of the première
for the new VIEROL MOBILITY TALK format,
which took place in mid-August at the
VIEROL ACADEMY in Rastede. The aim is to
promote exchange between workshops,
associations, educational institutions, trade
press, technology experts and VIEROL, and
to discuss future topics together.
Numerous representatives from regional
automotive guilds, training centres,
workshops and trade media attended the
première. For three hours, there was an
intensive discussion about the opportunities
and challenges presented by the use of AI in
everyday life.
A key topic was the EXPERT KIT FINDER:
This tool makes parts identification faster
and more precise. For workshops, this
means fewer incorrect deliveries, significant
time savings and always the right EXPERT
KITS+ from VEMO, VAICO and ACKOJA – a
clear contribution to process optimisation.
Education meets AI –
securing tomorrow’s skilled workers
The role of AI in education and training was
also a focus. Digital learning platforms
adapt to the learner’s pace and make it
easier to get started with complex topics.
AI-supported tools such as the EXPERT KIT
FINDER show trainees in practical terms how
to quickly find the right spare part. This
reduces errors, provides security and
increases the attractiveness of the profession.
VIEROL demonstrates that training is crucial:
For over 25 years, we have been training
young people in commercial and technical
professions, thereby securing skilled
workers for tomorrow – a contribution to the
future viability of the entire industry.
The first VIEROL MOBILITY TALK showed
that AI is no longer a topic for the future,
but is already creating real added value in
workshops today. The event marked
a successful start and is set to become
a permanent fixture at the VIEROL
ACADEMY in future.

STAY COOL,
PERFORM WELL –
LIKE ANTIFREEZE FOR
THE TEAM
In an interview with VIEROL, the two national players Luisa and
Carina talked about how they got into ice hockey – and why the
sport is so special to them. While Luisa picked up a racket more or
less by chance during a holiday in Heidelberg, Carina was determined
to wear the ‘cool kit’ even as a child – and has never taken it
off since.
Both emphasise that fun and team spirit are the basis. “We don’t
have lone wolves here – everyone fights for each other,” says
Carina. Luisa adds: “We just enjoy spending time together – on and
off the ice. You can feel it.”
A shared moment that gave us goosebumps: successfully qualifying
for the Olympics. “A dream we’ve had for years,” says Carina. “When
that decisive goal was scored, a huge weight was lifted.”
The role of sponsors was also discussed. Support from companies
such as VIEROL is "”worth its weight in gold,” emphasises
Luisa – precisely because many clubs would struggle to survive
without this assistance.
The Olympics are clearly the focus for the future. Both want not only
to participate, but also to “make an impact”. At the same time, they
have a message for young girls: ice hockey is a challenging but
incredibly rewarding sport – with highs, lows and lots of fun.

EIGHT QUESTIONS FOR
FRANZIMAUTO
ABOUT RUSTED LOVE, HONEST CARS AND
THE SMELL OF PETROL.
He is a presenter on the radio station
UNSERDING, has over 121,000 followers on
Instagram and spends every spare minute in
his garage – preferably with his
youngtimers: Mercedes W124, BMW E34 and
anything else that has character.
Franz Johann, better known by his handle
‘@franzimauto’, is all about attention to
detail, honest mechanics and a great deal of
passion for cars. Whether it’s a spare part, a
home-made solution or an improvised fix –
the main thing is that it works and remains
authentic.
We asked Franz eight questions – about his
favourite cars, oil-smeared moments spent
tinkering with engines, and the little
successes that you don’t find in the
showroom, but only under the car.

Powered by 34 | 35
VDRIVE: Franz, you host a morning show in
the morning and then you’re under the car in
the evening – what gives you more energy:
a microphone or a spanner?
This oldie has more character than a slice of
cheesecake wrapped in aluminium foil at a motorway
service station, but it drives like a sack of screws, is
always broken down – and yet it’s still a great car!
Franz: Actually, they complement each other
perfectly. Working in radio robs me of all my
mental energy, and the best way for me to
recharge my creative batteries is actually
with a spanner under the car. Doing such
hard, physical labour is the best way for me
to clear my head and recharge my batteries.
On the other hand, it’s not always easy when
you’re standing in the pit for what feels like
an eternity and having to do work above your
head. It’s also quite nice not to have to do
physical work on the radio.
VDRIVE: What is your definition of a ‘good
car’ – technology, character, condition or
simply gut feeling?
Franz: All FOUR! My Land Rover, for example,
is a really bad car, but it’s such a good car,
too! That makes sense, doesn’t it? This oldie
has more character than a slice of cheesecake
wrapped in aluminium foil at a motorway
service station, but it drives like a sack
of screws, is always broken down – and yet
it’s still a great car! I think character is the
most important thing about a car for me. And
if the technology is good, too – jackpot! Of
course, we cannot completely ignore what’s
going on at the moment. We are all engaged in
a relentless battle against pitting. And the
fewer crumbs there are under the car, the better.
But ultimately, everything can be
repaired. And those who are really passionate
about their cars will invest disproportionate
amounts of money in them. I must also clarify
one thing: I am only talking about young
classics and classic cars. Of course, there
are also some really good new cars. Cars that
drive superbly, are incredibly comfortable or
consume little fuel – but very few of them
have managed to retain the character of their
predecessors. Most of them are plastic
bombers “Made in China” and barely a means
of transport. My mate Manuel Huber once
said: “In the past, the journey was the destination,
but today, only the destination is the
destination.” Amen! Driving is so expensive, I
want to at least enjoy it!
VDRIVE: Your love for young timers such as
the W124 or E34 is immediately apparent –
what fascinates you about these particular
models?
Franz: These two cars are already incredibly
exciting. Both built in 1989, both roughly the
same size, both with similar price tags – and
both as different as two cars could possibly
be.
Let’s talk about my W124 230E first. Young
people are always asking me: “I want to buy
an old car too. What would you recommend?”
And my answer is always: “A 124 or 190, if the
garage is a bit tight.” My 124 was a panic buy.
I successfully drove my ‘77 Landy as my daily
driver for an entire season, but when it
started having engine problems, it was clear
that I needed to find a cheap winter car! For
days and weeks, my brother-in-law and I
leafed through the curious maze of classified
ads, battling our way through the thicket of
private listings, only to finally find a (far too
good) 124 in the Eifel region, which we took
home with us on the spot for three banknotes.
I’ve had it for almost two years now,
and it’s the most reliable daily driver I’ve ever
had!
After 36 years, the car is still as elegant and
majestic as ever. I’m travelling across Germany
in my ‘pensioner rocket’, and it’s every
bit as comfortable as you’d expect. And 1,000
km on a single tank of fuel – by then, the
electric car driver is already looking for their
third charging station.
The E34, on the other hand, is the complete
opposite! Okay, a little disclaimer: the car has
already been modified for racing, making it
harder, louder, faster and more aggressive
than the standard 525i. And yet: BMW builds
cars that are significantly sportier. While the
W124 glides majestically along the bends of
the country road, the E34 devours them like a
local football team devours currywurst at a
high street stall. Despite the size and weight
of the 5 Series, it drives much more sportily
and feels very modern in terms of handling.
I also love old saloon cars – guilty. And let’s
be honest: the E34 is the most beautiful car
in the E series. Now there’s an outcry among
E30 fans, but in my opinion, the E34 looks
much more aggressive, and the rear lights in
particular are more attractive and more in
keeping with BMW.
Continued on the next page.

VDRIVE
02 ||| 2025
Much ado about nothing: both the W124 and
E34 are cars with real character and could be
siblings. Siblings who are completely
different, bicker every ten minutes and are
not allowed to sit next to each other at
dinner. I just love them!
VDRIVE: What has been your biggest
mechanical mishap so far – and what did
you learn from it (apart from new swear
words)?
Franz: Touch wood: I haven’t had any really
serious mishaps when working on cars yet.
But that’s not because I’m such a good
handyman, it’s solely because I always do
difficult things with friends – and they have
an incredible amount of knowledge about
what they’re doing. None of my cars have had
any particularly tricky repairs so far either
(but let’s wait and see how things turn out
with the single throttle on the BMW).
Franz: I always find it strange when people
insist on ‘ORIGINAL’ when it comes to classic
cars. Many things were already great when
the car was invented back then – no question
about it – but it stands to reason that today
we can build some parts better than was possible
back then. Manufacturing processes
have changed and new materials have
entered the market. It goes without saying
that this has also led to improvements in
spare parts (with some exceptions). That’s
why I often opt for aftermarket parts, and so
far it’s worked out well for me!
VDRIVE: You reach over 116,000 people with
your car posts – can you explain why the
topic of “old cars” is inspiring so many
people?
Franz: It’s wonderful to see so many young
people suddenly developing an interest in tin
dinosaurs again. Time and again, people in
my DMs as me which classic car I would
recommend and which would be particularly
suitable as a first car after getting your
driving licence. I would like to give
everyone a hug!
New cars are increasingly merging into a bland
soup of equally boring-looking plastic bombers with
forced touchscreen marriages.
That said, I always end up forgetting
something. My memory could be an air filter
– there are so many little holes in it. And it’s
always only when I’ve finished putting
everything together that I realise I’ve
forgotten to include a part, and that’s when I
start dismantling.
VDRIVE: When it comes to replacements, do
you prefer used parts, original parts or
high-quality aftermarket parts such as those
from VEMO or VAICO? What has proven
most effective for you in practice?
An Old BMW, a cold garage and passion –
Franz and his E34.
Between his toolbox and spanner,
Franz embodies what true car love is all
about: oil, patience and a passion for old
bangers.

I think there are quite a few reasons for this
trend. On the one hand, it’s because new cars
are virtually unaffordable. It’s unlikely that
anyone who has already paid over €2,000 for
their driving licence will have the money to go
out and buy a new BMW 1 Series unless they
have rich parents. Even lease returns and
year-old cars have price tags that should
really come with a side of therapy. Of course,
a young classic or classic car in the low
thousands is a bargain in comparison.
The character of old cars also impresses
many young people. New cars are
increasingly merging into a bland soup of
equally boring-looking plastic bombers with
forced touchscreen marriages. Many young
people remember old classics from their
childhood. Granddad picked us up from
nursery in his old Kadett C. Fortunately, a
connection to real cars was established at an
early age.
And what I also believe is a real reason: it’s
the new en-vogue hobby! While some people
are still baking banana bread or growing new
plants from avocado pits, which return to the
eternal vegan realm after two weeks on the
windowsill, there are many young people who
are taking an interest in craft hobbies. Which
cars are best to work on? If I can tinker with
vintage cars, then anyone can!
VDRIVE: If you could only drive one car for
the rest of your life, which one would it be
and why?
Franz: That sounds like a terrible idea. I
never want to lose the luxury of being able to
change cars every now and then. I look forward
to getting into my car every single time.
But well, if I have to choose: then I would be
the Benz! If it were a 500E, I would have absolutely
no problem driving it every day. It’s
comfy, sporty, timelessly beautiful – this car
is simply perfect!
VDRIVE: What would you say to someone
who thinks, “What an old car?” Far too much
work, I’m better off going for something new
with a warranty!
Franz: Yes, well, they’re just missing the
point. There are people out there who think
that a Margherita pizza is a good choice if
you can put spicy salami on the dough. I
enjoy driving a new car every now and then
and am often impressed by what some car
manufacturers are now capable of achieving.
But I didn’t want to own one. The fewer
features and things that can break, the
better. And even if a car has a warranty,
having to go to the authorised repair shop for
every little thing is as enjoyable as having a
stone in your shoe.
My girlfriend drives a more modern car than I
do and always says, “There’s never anything
wrong with your cars.” And my answer is
always: “There’s always something wrong
with every one of my cars!” Most of the
time, though, I know exactly what it is,
and I look forward to repairing the old
car with classic rock blaring from my
speakers and a cold beer in my
hand until the next defect rears its
head. It’s all a matter of attitude!
VDRIVE: Thank you very much,
Franz! For your time, your stories,
your humour – and for the
passion you share with us and
so many others when it comes
to cars. Whether under the car,
behind the microphone or in
front of the camera: please
stay exactly as you are – honest,
tinkering and with a big
heart for old bangers.

Driver profile Dennis Fetzer
Dennis Fetzer was born on 28 May 2001 in
Buseck (Hesse). His first experience was in
a go-kart at the age of eleven. A year later,
and he competed in his first races at the
ADAC Youngster Cup. With successes in
karting – including the championship title
in the Rotax DD2 class in 2016 – he paved
his way into professional GT racing. After a
successful test with Porsche, he made his
début at the one-make cup in 2019 and
impressed in 2020 at the ADAC GT4
Germany and at the 24-hour race at the
Nürburgring (2nd place in the SP10 class).
2021 saw his GT3 début at the 24-hour race
in Sebring. In the years that followed, he
achieved further successes in the GT World
Challenge Europe and the Nürburgring
Endurance Series. Dennis has been
competing in the ADAC GT Masters since
2024 and is setting his sights on the DTM
using the Road to DTM programme.

INTERVIEW WITH DENNIS FETZER
RACING DRIVER,
MECHANIC,
TAXI DRIVER –
ALL THAT’S MISSING IS THE INTERCHANGEABLE NUMBER PLATE
With 24 hours of flat-out racing on the Nordschleife, strong performances in the ADAC GT
Masters and the Ford Mustang GT3 behind him, Dennis Fetzer is no longer an unknown
quantity on the GT scene. In 2025, he will take on the next big hurdle as part of the
‘Road to DTM’ programme – and will be accompanied by VAICO, among others.
Born in Hesse, he not only has a knack for driving, but also for honest craftsmanship:
his family business has been using VAICO products for years. Whether as a driver in the
VAICO Porsche at the Track Experience or as a GT driver in fierce competition –
Dennis loves what he does. In the interview, he talks to us about pressure to perform,
team spirit, steep learning curves and why the right partners on and off the track make
all the difference.
VDRIVE: Dennis, you are part victory at the Nürburgring 24 Hours, which
of the "Road to DTM"
for me is the best race on the planet.

With VAICO as a strong partner at your side, are excellent.
what does this combination mean for your
personal career development?
VDRIVE: As a long-standing GT driver with
successes in the ADAC GT Masters and

advancing in this sport. The first half of the
season is already over, and it has not been as Dennis: The ADAC GT Masters is particularly
successful as we had hoped in the ADAC GT interesting to me because of its format, with
Masters. However, we were able to achieve a races usually lasting one hour, and the overall
very good fourth place overall and class schedule. Most of the events take place in
conjunction with the DTM and on the best
tracks. This fantastic package is always
a magnet for fans. What I enjoy most is when
you start the race as the second driver on
race day, and you haven’t driven a single
metre before the driver change so you’re
literally thrown in at the deep end. It’s an
exciting challenge to go straight from
0 to 100.
VDRIVE: You’ll be stepping onto the DTM
stage with VAICO as your official partner.
What role do sponsors such as VAICO play
in your everyday life as a professional –
both on and off the track?
Dennis: Another distinctive feature of this
partnership is the company's overall image
and presence. You see countless VAICO/
VIEROL banners along every route, which
naturally makes you particularly proud to
compete for the company and represent
it as an athlete.
I should also mention that at our company,
which has now been going for 95 years,
we have been relying on VAICO and
VIEROL products for many years, and I am
therefore in daily contact with the products.

VDRIVE: The DTM environment is
considered extremely competitive
– with its proximity to the
factory, TV presence and intense fan
loyalty. How does this additional pressure
motivate you – and what expectations do
you have of yourself for this new challenge?
Dennis: Fortunately, I’m now quite good at
blocking out external influences. But it took
a long time to learn these things. In the past,
interviews would have driven me absolutely
mad. Today, I’m appearing for five minutes on
the live broadcast of the 24-hour race, and
I’m delighted to see smiles on people’s faces
time and time again. I don’t pretend to be
someone I’m not, especially for the media. I
am always myself and I think it’s important to
be authentic.
VDRIVE: In 2024, you were already able to
deliver strong performances in the ADAC GT
Masters with the Haupt Racing Team How
did this experience prepare you for your
possible entry into the DTM – both in terms
of driving and mentally?
Dennis: The successful guest start with
Hubert Haupt was a test to see whether it
would work in sprint format as well as on the
Nordschleife in GT3. This test has made us
feel positive about taking this path.
VDRIVE: You are familiar with both sprint
and long-distance formats. Both the ADAC
GT Masters and the DTM combine sprint
racing with strategic depth. Which skills
from your previous career are particularly
helpful here?
Dennis: From long-distance running in
general, the ability to concentrate and adapt
quickly to the prevailing circumstances.
Also the direct retrieval of services. I find it
easy to get into the racing car and give it my
all. In some cases, it also helps to adopt a
more cautious driving style from the long
distance, as a race is not decided in the first
lap.
VDRIVE: In addition to your racing
commitments, you also drive for guests in the
VAICO Porsche. How do you feel when you
get to pass on that racing feeling to them –
and what makes this role special for you
personally?
Dennis: Personally, I love campaigns like
this. You have the opportunity to share your
passion with a guest in a completely different
way. When you see that your passenger is just
as enthusiastic as you are, the joy is even
greater. I myself am always amazed at how
great cars can drive, especially when you’re
pushing them to their limits. Being able to
share this enthusiasm on a 1:1 basis is
simply incredible. A great opportunity to be
right in the thick of things, rather than just
watching from the sidelines.
VDRIVE:We would like to thank you, Dennis,
for your honest insights and for giving us the
chance to take a look behind the visor.
Whether you’re in GT3, with VAICO Porsche
or on the way to DTM: we are delighted to
have you as a strong partner
at our side and wish you
continued success, speed
and safe laps!

ACADEMY and consolidate our position in
the workshop market with our range of
services,” says Jan Knoll, Managing Director

The cooperation is long-term and aims to
strengthen the competitiveness of the
affiliated companies. Close cooperation
should also generate practical ideas for the

important market for us, and strengthening
independent workshops is of strategic
importance,” adds Ibrahim Chahrour, Head of
Marketing & Innovation Management at
VIEROL AG. “With a comprehensive allround
package, our experts support
workshop partners in actively developing
their market with marketing support, training
and a range of services.”
