Volkswagen Golf Service & Repair Manual: Tyre pressure monitor

System description – Tyre Pressure Monitoring System

General notes:
The tyre pressure monitor display system is part of the software in the ABS control unit -J104-. The system is used to detect slow tyre pressure loss from a wheel. Event memory entries for the tyre pressure monitor display are stored in the ABS control unit -J104-. The tyre pressure monitor display compares the wheel speeds and consequently the rolling circumferences of the individual wheels with the help of the ABS speed sensors.
After the following work or modifications, the tyre pressure monitor display button -E492- must be pressed and held until a confirmation is sounded.
Change in tyre pressures
Changing one or more wheels
Interchanging wheels, e.g. from front to rear
Removing and fitting one or more wheels
A change in a wheel's rolling circumference will be indicated by the tyre pressure monitor warning lamp -K220- lighting up in the dash panel insert. A tyre's rolling circumference may change as a result of:
Insufficient tyre inflation pressure.
Structural tyre damage.
One-sided loading of vehicle
Increased load on one axle, e.g. due to towing a trailer
Use of snow chains.
Temporary spare wheel installed
Wheel renewal
System fault in the ABS system
   
If a fault in the ABS is displayed by the ESP and TCS warning lamp -K155- then the Tyre Pressure Monitoring System warning lamp -K220- will also light up. However, no fault will be stored in the system for the tyre monitor display.
The warning lamp cannot be erased. In this case, please carry out the following steps:
