Q7 Quattro V8-4.2L (BAR) (2008)
NOTE:
-
If measured value is 0 ohm there is a short circuit. If measured value is infinity ohms there is and open circuit in the wiring.
-
To check "tank full" or "tank empty" resistance values, the fuel level sensor 2 G169must be removed, and the sensor floater must be placed in
inner or lower end position.
-
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 990 ohms.
-
Sensor at upper stop: approximately 51 ohms.
Assembly is in reverse order of removal, note the following:
-
Install locking flange cover.
-
Install tank access carpet frame in floor covering.
-
Install 2nd row left seat cushion.
