Run-flat Reset (RPA – Tyre Deflation Detection)
The run-flat system monitors the pressure in the four mounted tyres while the vehicle
is being driven.
The system will provide an alert whenever the inflation pressure in a tyre drops
significantly in relation to the pressure of another tyre.
It is necessary to initiate the RPA reset process IMMEDIATELY after every tyre
pressure correction, after a tyre or wheel change or after a trailer has been attached
or detached. The reset MUST be started before driving the vehicle for the first time
after one of the above events.
When a reset is required (due to a pressure change in one of the tyres) the vehicle
will inform the driver by turning on the RPA Warning Lamp, which will glow red, and
sounding an acoustic signal.
When the RPA Warning Lamp is on but the colour is yellow this indicates that the RPA
system has failed or is malfunctioning. In this case the system must be diagnosed
using a BMW OmiCheck.
The RPA reset process is as follows:
• Start the engine but do NOT start driving.
• Press the RPA Reset button (shown in the diagram below) and hold down for at
least 5 seconds, or until the RPA Warning Lamp on the indicator panel glows
yellow.
