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

Sedan:

- Remove carpeting in luggage compartment.

- Fold forward the right backrest of rear seat, if necessary.

• 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 delivery unit must be removed. Refer to => [ Fuel Delivery Unit ] Removal and Replacement 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:





Assembly is in reverse order of removal.
