A3 Quattro V6-3.2L (BUB) (2008)
NOTE:
-
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.
-
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.
-
With fuel level sensor G removed, the following values are obtained because of the greater deflection of the floater arm:
Fuel Level Sensor G removed:
-
Sensor at lower stop: Approximately 299 Ohms.
-
Sensor at upper stop: Approximately 86.4 Ohms.
Assembly is in reverse order of removal, note the following:
-
Install rear seat bench
Vehicles from approximately 11/2004:
NOTE: On vehicles with 3-wire sensor technology, the connector for fuel level sensor G is equipped with 5 terminals.
-
Connect multimeter between terminal - 2 - and - 3 - for resistance measurement.
Fuel Level Sensor G installed:
-
Sensor at lower stop: Approximately 270 Ohms.
-
Sensor at upper stop: Approximately 70 Ohms.
