Fuel Level Sensor 2 (G169), Checking

Special tools, testers and auxiliary items required

Multimeter (V.A.G 1526E)

Connector Test Set (V.A.G 1594C)

Carpet knife, commercially available

Procedure

- Remove the left single seat and the left 2/3 seat bench seat cushion in the second row of seats.

Risk of injury.

Wear protective gloves.

- Cut the floor covering along the perforation - arrows - on the left side with a carpet knife - 1 -.

- Remove the nuts - 1 to 4 - and remove left locking flange cover.

- Disconnect the electrical connector - arrow - on the left locking flange.






- Connect multimeter between terminals - 2 - and - 3 - to measure resistance.






Fuel level sensor 2 installed:

Sensor at lower stop: 760 to 842 ohms.

Sensor at upper stop: 67 to 86 ohms.

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

To check resistance values "tank full" or "tank empty", the fuel level sensor 2 must be removed. Refer to => [ Fuel Level Sensor (G) ] Fuel Level Sensor (G) and the sensor floater must be placed in the upper or lower end position.

With fuel level sensor 2 removed, the following values are obtained because of the greater deflection of the floater arm:

Fuel level sensor 2 removed:

Sensor at lower stop: approximately 990 ohms.

Sensor at upper stop: approximately 51 ohms.

Assemble in reverse order of disassembling. Note the following:

- Connect the connector - arrow - at left locking flange.






- Install the left locking flange cover. Refer to => [ Locking Flange Cover - Tightening Specifications ] Fuel Tank With Attachments With Reducing Agent Metering System Overview.
