Guided Fault Finding, Special Notes

Guided Fault Finding, Special Notes

Selector Lever Position Display - No "R"

Simultaneous lighting of all segments of Transmission Range (TR) selector lever display indicates transmission is in emergency running mode. The vehicle does not drive in reverse.

Tip Function Malfunction, No Normal Gear Selection

Check lock washers on selector lever cable mounting bracket at top of transmission. Washer - B - must never be used twice.





This washer can be lost due to a loss of tension. - Arrow - points to cable adjustment screw.

Drive Faulty, Insufficient Oil Suspected

=> [ Transmission Oil and Filter ] Transmission Oil and Filter

Only add oil if you have definitely seen: oil is leaking.

No DTCs Stored

Experience shows that often a "DTC" that is attributed to the transmission was caused by other components or modules.

It has occurred that poor shifting behavior was a result of insufficient engine air supply. Do not make mistakes like this.

If such DTCs are to be eliminated, you can work sensibly with the VW tester.

DTCs Stored

The VW tester offers Guided Fault Finding possibility. You can find many causes of DTCs when the Guided Fault Finding is used correctly.

Non-Transmission DTCs

If, for example, the DTC: "ABS signal missing" is stored in the transmission and perhaps another control module also says: " ABS signal missing", you should not continue to suspect the transmission control module is faulty.

The entry simply means: The transmission (and possibly other control modules) is waiting for a signal via the BUS but is not receiving it. In this case, the ABS control module has a problem. Under no circumstances should you remove the Direct Shift Gearbox (DSG) Mechatronic ( J743) without stopping to think. In this example, the DTCs points to problems with the ABS.
