• The target pressures are stored in the tire pressure monitoring control module (J502) and only need to be changed if the wheel dimensions have changed, for example if different summer or winter tires are installed. The system automatically learns new or different wheel electronics.
Tire Pressure Sensor
Special tools, testers and auxiliary items required
• Torque Wrench (V.A.G 1410)
Removing
- Remove the tire from the disk wheel. Refer to => [ Tires, with Tire Pressure Monitoring System ] Tires, with Tire Pressure Monitoring System.
- Unscrew the bolt - arrow - for the tire pressure monitoring sensor - 1 -.
- Counterhold metal valve using retainer (for example 2 mm spiral bore) while doing so.
Installing
• Clean the valve opening before installing the tire pressure sensor.
- Press the tire pressure monitoring sensor - 1 - onto the disk wheel (rim) and tighten - arrow -.

Metal Valve
Special tools, testers and auxiliary items required
• Torque Wrench (V.A.G 1410)
Removing
- Remove tire pressure sensor. Refer to => [ Tire Pressure Sensor ].
- Remove the nut - 1 - from the metal valve.
- Counterhold - arrow - the metal valve using a retainer (for example 2 mm spiral bore) while doing so.
Installing
• Only apply the specified torque to tighten the nut for the metal valve. Tightening more is not permitted because it damages the seal.
- Tighten the nut - 1 - of the metal valve.
- Counterhold - arrow - the metal valve using a retainer (for example 2 mm spiral bore) while doing so.
- Install tire pressure sensor. Refer to => [ Tire Pressure Sensor ].
