and activate the solenoid valve to be tested.

Connect diode test lamp V.A.G 1527 A with test leads from V.A.G 1594 to the corresponding connector contacts:

Component · Contacts on connector
Solenoid valve 1 -N88 · M + H
Solenoid valve 2 -N89 · M + K
Solenoid valve 3 -N90 · M + L
Solenoid valve 4 -N91 1) · M + B

Note test requirements

Test requirements for solenoid valve 4 -N91:

To test activation of solenoid valve 4 -N91, the connector contacts M and B with test leads from V.A.G 1594 must be connected to the contacts M and B of the plug connector. In parallel with the above, the diode test lamp V.A.G 1527 A must be connected, i.e. the diode test lamp must also be connected from M to B.
For the 55-pin gearbox control unit, this test can also be performed with the plugged-in connector and using test box V.A.G 1598 A => Electrical test, test step "Activation of solenoid valve 4 -N91" from Page

.

The diode test lamp must flash on actuation of the relevant solenoid valve in the final control diagnosis.

If the diode test lamp does not flash on actuation of the solenoid valve:
