Slacken bolts -right arrows-.

Release bayonet fitting on 8-pin connector -arrow- by turning anti-clockwise. Remove connector from gearbox.
With the ignition switched off, connect test box V.A.G 1598 A with adapter V.A.G 1598/5 only to connector for gearbox control unit (control unit not connected)=> Page

.
Set down the test box outside of vehicle.

Test for open circuit in the following wiring connections:

Connector / contact · Test box V.A.G 1598 A / socket
B · 6
D · 25
H · 5
K · 24
L · 42
M · 19

Note:

Pay special attention to possible contact corrosion, leaks and moisture in connectors.

If no wiring fault is detected:

Testing wiring harness in gearbox

Note:

Perform this test if the solenoid valves do not click during final control diagnosis or the electrical test of the solenoid valves via test box V.A.G 1598 A detects a fault, but the wiring connections between the gearbox control unit and the 8-pin connector are in order.

Connect multimeter (resistance measurement range) as follows:

Component · Connector contacts · Specification ω
Solenoid valve 1 -N88 · M + H · 30 ... 40
Solenoid valve 2 -N89 · M + K · 30 ... 40
Solenoid valve 3 -N90 · M + L · 30 ... 40
Solenoid valve 4 -N91 · M + B · 5 ... 8
Solenoid valve 5 -N92 · M + D · 5 ... 8

If a specification is not met:

Disconnect wiring harness from relevant solenoid valve and test wiring connection from 8-pin connector to solenoid valve. If necessary, replace wiring harness.
Measure resistance at solenoid valve again and replace solenoid valve if necessary.
