A3 Quattro L4-2.0L Turbo (CBFA) (2009)
Fuel Level Sensor 2 (G169) installed:
‹› Sensor at lower stop: 265 to 291 ohms.
‹› Sensor at upper stop: 47.5 to 73 ohms.
‹› To check resistance values "tank full" or "tank empty", the Fuel Level Sensor 2 (G169) must be removed => [ Fuel Level Sensor 2 ] See: Service
and Repair/Fuel Level Sensor 2 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:
‹› 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.
