Fuel Level Sensor G, Checking
Special tools, testers and auxiliary items required
- Portable multimeter V.A.G 1526 B
- Connector test set V.A.G 1594 C
Test sequence
Sedan:
- Remove carpeting in luggage compartment.
- Fold forward right rear seat backrest, if necessary.

- If measured value is 0 Ohm 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 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:
