- Connect VAG1598 tester with VAG1598/25
adapter to the blue 32-pin connector.

- Perform an acoustic continuity check of the
sensor and wire using the VAG1526 multimeter
between terminal 28 and socket 9 (load Ground
(GND))
Test
The beep signal of the resistance tester must
switch on and off several times while the vehicle
is rolled slightly forward and backward (approx.
1m)
If the test is not OK, the wire connection to speed
sender must be checked.

- Check wire connection according to wiring
diagram.

- Measure resistance (sensor resistance) between
terminal 5 and 7 using VAG1526 multimeter.
Specified values:
Fuel tank empty: approx. 280 Ohm (Front Wheel
Drive/All Wheel Drive)
Fuel tank full: approx. 40 Ohm (Front Wheel
Drive/All Wheel Drive)

- If the specified values are not reached, check
wire connection between instrument cluster and
the sender for fuel gauge -G- (Front Wheel
Drive/All Wheel Drive) according to wiring
diagram.

Electrical Wiring Diagrams, Troubleshooting &
Component Locations
- If there is neither an open circuit nor a short
circuit, check the sender for fuel gauge -G-
(Front Wheel Drive/All Wheel Drive)

- Measure resistance (sensor resistance) between
terminal 8 and 7 using VAG1526 multimeter.
Specified values:

Coolant temperature 90 C: approx. 110 Ohm
Coolant temperature 120 C: approx. 50 Ohm If the specified values are not reached, the wire
connection to Engine Coolant Temperature
(ECT) -G2- must be checked.

- Check wire connection according to wiring
diagram.
