Note the following when connecting to VW/Audi vehicles:
• “Bonnet” is European for hood.
• Do not assume that the scan tool ID screen is correct if the scan tool communicates. If there
are multiple selections, the scan tool will automatically identify the electronic control module,
which means that scan tool communication does not depend on a correct engine ID code
selection.
3.3 Selecting a System
Once you have confirmed a vehicle identification and connected to a vehicle (see previous
sections), the Select System menu displays.
The items that appear on this menu vary depending on the vehicle you are testing, however, not
all of the systems will be present—some of them are optional and others are mutually exclusive.
For example, when an integrated immobilizer is present, there will be no separate immobilizer
available.
NOTE:
i Some early control modules may require an engine speed below 2000 RPM and a closed throttle
(closed CTP switch) to initialize communication. However, once communication has initialized,
higher engine speeds have no effect.
