Test requirements

-

The Direct Shift Gearbox (DSG) Mechatronic J743 fuses OK.

-

The Power Supply Relay (terminal 15) J329 OK.

-

Battery voltage at least 12.5 volts.

-

All electrical consumers such as, lights and rear window defroster, switched off.

-

Selector lever in "P" or "N".

-

A/C switched off.

-

Ground (GND) connections between engine/transmission/chassis OK.

-

Ignition switched off.

Test procedure

-

Perform a preliminary check to verify the customers complaint.  See: Computers and Control Systems/Testing and Inspection/Scan Tool Testing
and Procedures/Preliminary Check

Start diagnosis

-

Disconnect the Direct Shift Gearbox (DSG) Mechatronic J743 electrical harness connector - 1 - by rotating counterclockwise.

Checking voltage supply, terminal 30

-

Using a Multimeter, check the Direct Shift Gearbox (DSG) Mechatronic J743 electrical harness connector terminals for voltage.

Direct Shift Gearbox (DSG) Mechatronic J743 electrical harness connector terminals
11 to 16
11 to 19

Specified value: battery voltage.

If the specified value was not obtained:

-

Check the wiring connection for an open circuit, short circuit to Battery (+) or Ground (GND).

-

Check the wiring connection for damage, corrosion, lose or broken terminals.

-

If necessary, repair the faulty wiring connection.

If the wiring and voltage were OK:

Voltage supply, terminal 15

-

Using a Multimeter, check the Direct Shift Gearbox (DSG) Mechatronic J743 electrical harness connector terminals for voltage.
