VAG: clutch control differs from expected, second circuit

Code of a VAG dual clutch gearbox. The transmission control unit found the clutch tracking abnormal. Together with P0805 and P1735 it points to the clutch position sensor.

The code tells you what the control unit measured, not which part has failed. The same code has several possible causes.

This is a manufacturer specific code. Its meaning differs by brand, so there is no answer to it without knowing the model.

Which known faults it comes up with

DQ381 (7 speed wet DSG): mechatronics and clutch position sensor

expensive

The 7 speed, wet clutch DSG that replaced the DQ250 in the MQB models (0GC / DQ381) is vulnerable from the mechatronics side. Typical faults are a harsh 2 to 3 shift, delayed D/R engagement and limp mode; a fault in the clutch position sensors gives a separate group of codes.

Show the rest

The wet clutch is more durable than the dry one, but as it wears you get shuddering and slipping when pulling away: the revs flare and the acceleration does not follow.

What to check

Standing still on the brake, shift between D and R and watch the engagement time and any jolt
Try pulling away on a slope too: shuddering, or revving without pulling, points to clutch wear
On the test drive watch the 2 to 3 shift specifically, cold and warm

Information, not an expert opinion

We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.

A fault on the list does not mean the car you are looking at has it.
A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
