Removing and installing tyre pressure sensor, metal valve body

Special tools and workshop equipment required

Torque wrench -V.A.G 1410- and 11 mm insert tool-V.A.G 1331-.

• Push metal valve with rubber seal through the rim from the inside.
• Fit chamfered washer and union nut from outside, and screw it in by hand.
• Tighten union nut.

If the wheel trim is damaged, renew wheel rim.

1. 1
   Tyre Pressure Monitoring (TPMS): direct measurement. Tyre pressure sensor installed on metal valve in wheel; pressure and temperature values are sent and analysed periodically.
2. 2
   TPLI+, indirect measurement No tyre pressure sensor is installed in the wheel. Instead, the rolling circumference and vibration on each wheel are compared by analysing the signals from the ABS sensors. The pressure loss is determined indirectly. If the tyre pressure changes, the speed and the vibration on the respective wheel will change as well.
3. 3
   TPLI, indirect measurement No tyre pressure sensor is installed in the wheel. Instead, the rolling circumference on each wheel are compared by analysing the signals from the ABS sensors. The pressure loss is determined indirectly. If the tyre pressure changes, the speed on the respective wheel will change as well.

• Use a suitable tool -1- (e.g. a 2 mm drill bit) to prevent turning.

If the wheel trim is damaged, renew wheel rim.
