A3 Quattro V6-3.2L (BUB) (2008)
-
Sensor at upper stop: 47.5 to 73 Ohms.
NOTE:
-
To check resistance values "tank full" or "tank empty", the Fuel Level Sensor 2 G169 must be removed and the sensor floater must be placed
in upper or lower end position.
-
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.
-
With Fuel Level Sensor 2 G169 removed, the following values are obtained because of the greater deflection of the floater arm:
Fuel Level Sensor 2 G169 removed:
-
Sensor at lower stop: Approximately 299 Ohms.
-
Sensor at upper stop: Approximately 36.6 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 technology, the connector for Fuel Level Sensor 3 G169 is equipped with 3 terminals.
-
Connect multimeter between terminal - 1 - and - 2 - for resistance measurement.
Fuel Level Sensor 2 G169 installed:
-
Sensor at lower stop: Approximately 270 Ohms.
-
Sensor at upper stop: Approximately 70 Ohms.
