🧭 Before you start
Fits: Audi A3 (8P, 2003–2012)
- Renewed: damaged sensors
Don't miss
- After installation, the tyre pressure sensor must be seated firmly against the base of the rim.The sealing washer (arrow) will be deformed slightly when the nut is tightened.
🔩 Torque settings
Values can differ between engine variants — check the code stamped on your block.
| Torque | Fastener / step |
|---|---|
| 8 Nm (5.9 lb-ft) | Press tyre pressure sensor(1) onto bed of rim at the points marked by (arrows) and… |
ℹ️ Always cross-check the exact figure against your vehicle's factory manual before final tightening — a wrong torque can damage the engine. These values are extracted from workshop data and may not cover every variant or revision.
📋 Procedure
- Remove union nut (1).
- Remove tyre pressure sensor(2) from base of rim. [Note: Always renew damaged sensors.When fitting used tyre pressure sensors, inspect the connection between the sensor and the valve for damage.If tyre sealant has been used, wipe the tyre pressure sensor clean without removing it and make sure that the aperture for the pressure sensor is not obstructed. If the aperture is obstructed, the tyre pressure sensor must be renewed to prevent incorrect readings.Do not use steam cleaners or a powerful jet of compressed air to clean the tyre pressure sensor.Hold the valve body when sliding on the new seal and sealing washer to prevent it from being pushed out (this could damage the aerial connection).]
- Insert tyre pressure sensor with new seal and sealing washer through rim from inside and press seal into valve aperture Electronic parts catalogue.
- Screw union nut (1) onto tyre pressure sensor(2).
- Press tyre pressure sensor(1) against base of rim and tighten union nut . [Note: After installation, the tyre pressure sensor must be seated firmly against the base of the rim.The sealing washer (arrow) will be deformed slightly when the nut is tightened.]

Who makes these pages, and how
TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.
The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.
Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
