Fuel Level Sensor, Checking

Fuel Level Sensor, Checking

Special tools, testers and auxiliary items required

• Hand-Held Multimeter (V.A.G 1526C)

• Connector Test Set (V.A.G 1594C)

Test Sequence

- Remove rear seat bench.

- Remove cover - arrows - for right locking flange.





Audi RS4:

- Remove electrical wires with connector - arrow - from locking flange opening and lay them aside.





All:

- Disconnect electrical harness connector - arrow - at right locking flange.





- Connect Hand-Held Multimeter (V.A.G 1526C) between terminal - 2 - and - 3 - for resistance measurement.









• If measured value is 0 ohms there is a short circuit. If measured value is infinite ohms there is and open circuit in the wiring.

• To check resistance values "tank full" or "tank empty", the Fuel Level Sensor (G) must be removed. Refer to => [ Fuel Level Sensor ] Service and Repair and the floater of the sensor must be placed in upper or lower end position.

• With Fuel Level Sensor (G) removed, the following values are obtained because of the greater deflection of the floater arm:
