Fuel Level Sensor G , Checking

Special tools, testers and auxiliary items required







- Portable multimeter V.A.G 1526







- Connector test set V.A.G 1594 C

Test sequence

Sedan:
- Remove carpeting in luggage compartment.
- Fold forward right rear seat backrest, if necessary.

Wagon:
- Remove left 1/3 backrest.

All models:







- Unbolt cover for locking flange in luggage compartment - arrows - .







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







- Connect hand multimeter V.A.G 1526 B between terminal - 2 - and - 3 - for resistance measurement.







NOTE:
- If measured value is 0 ohm there is a short circuit. If measured value is infinity ohm there is and open circuit in the wiring.
- To check resistance values "tank full" or "tank empty" , the fuel delivery unit must be removed 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:







Installation is in reverse order or removal.
