BMW X3 Service & Repair Manual: Initializing run flat indicator (rpa)
NOTE: Checking the tire pressure is based on speed monitoring of the wheels in relation to each other. A tire puncture is detected and signalled by way of a deviation in specific speed ratios.
The four tires mounted on the vehicle are monitored while the vehicle is driving.
Initialization must be carried out in each case immediately after tire pressures have been corrected, after tires/wheels have been exchanged and after repair work to the air spring system.
IMPORTANT: The Run Flat Indicator does not function when the vehicle is driven with the compact spare wheel.
RDC RESETTING
NOTE: RDC monitors the tire pressure in the four wheels.
Each tire incorporates an Wheel electronics module, which constantly monitors the tire pressure.
The system signals when the tire pressure drops in one or more tires.
Resetting must be carried out in each case immediately after tire pressures have been corrected, after tires/wheels have been replaced and after repairs to the air spring system.
Please refer to the relevant Owner's Handbook for details of the resetting procedure.
