FUEL LEVEL SENSOR, CHECKING
Special tools and workshop equipment required
- Hand-Held Multimeter V.A.G 1526E
- Connector Test Set V.A.G 1594 C
- Carpet knife, commercially available
Procedure
Remove the right single seat in the second row of seats. Refer to Removal and Installation .
| WARNING | Risk of injury. Wear protective gloves. |
Cut the floor covering along the perforation -arrows- on the right side with a carpet knife -1-.
Fold carpet cut-out to side -arrow-.
Remove nuts -1 to 4- and remove right locking flange cover.
Disconnect the connector -3- on the right locking flange.
Scheme 247
Note. Ignore -1 and 2-.
Connect multimeter between terminal -2- and -3- for resistance measurement.
Scheme 248
Fuel level sensor -G- installed
- Sensor at lower stop: 863 to 960 ohms.
- Sensor at upper stop: 67 to 86 ohms.
Note. If measured value is 0 ohms there is a short circuit. If measured value is infinity ohms there is and open circuit in the wiring. To check resistance values for tank full or tank empty, the fuel level sensor must be removed. Refer to Fuel Level Sensor -G and the floater of the sensor must be placed in upper or lower end position. With fuel level sensor removed, the following values are obtained because of the greater deflection of the floater arm
Fuel level sensor 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
Connect the connector -3- at right locking flange.
Note. Ignore -1 and 2-.
