Connect hand multimeter V.A.G 1526 B between terminal - 2 - and - 3 - for resistance measurement.

Sensor installed	Sensor at lower stop	Sensor at upper stop
Fuel Level Sensor G	300 to 310 Ω	53.5 to 59 Ω

NOTE:

If measured value is 0 Ω there is a short circuit. If measured value is ∞ Ω there is and open circuit in the wiring.
To check resistance values "tank full" or "tank empty" , the fuel delivery unit must be removed → Fuel delivery unit, removing and installing and the floater of the sensor must be placed in upper or lower end position.
With fuel level sensor G removed, the following values are obtained because of the greater deflection of the floater arm:

Sensor removed	Sensor at lower stop	Sensor at upper stop
Fuel level sensor G	271 to 296 Ω	55 to 69 Ω

Installation is in reverse order or removal.
