With All Wheel Drive

Sender for fuel gauge, checking - All Wheel Drive

Special tools, testers and auxiliary items
- V.A.G 1526 A
- V.A.G 1594 A

Test sequence
- Remove rear seat







- Unscrew screws -arrow- and remove cover for catch flange







- Disconnect connector -arrow-







- Connect the multimeter for voltage measurement to contacts 2 and 3

Empty Full
approx. 70 Ohm approx. 270 Ohm

- If the measured value is 0, there is a short. If the measured value is (1) there is an open

NOTE:
- -G-, -G169-, and -G237- are switched in a row. For that reason all 3 are tested together.
- To test a single Sender, it must be removed
- To test the resistance value of "Full tank" and/or Empty tank" swing the float to either the upper end position and/or the lower end position
- If a malfunction is suspected, check the resistance value of the installed Sender 3 (dependent on the level) by disconnecting the connector at Sender 2 and measuring resistance at that connector.

With sender for fuel gauge or fuel level sensor removed, the following values will result due to the longer reach of the float arm:

Vehicles with build date up to approx. 02/99







NOTE: On vehicles with a build date up to approx. 02/99, if any of the Senders for fuel gauge are found defective, all 3 Senders must be replaced with those for vehicles with later build dates. Connect the multimeter for voltage measurement to contacts 2 and 3.

Vehicles with build date as of approx 02/99





NOTE: As of the approx build date of 02/99, the resistance value range of Senders II and III were changed. The total resistance value however stayed the same.
