DSG 7 DQ200 TCU repair

24-month warranty1–3 day turnaroundTracked return deliveryRepair or replacement

Two ways to fix the DSG 7 DQ200 TCU, fitted to Audi, Seat and Skoda models. Listed under part number 0AM927769K. Repair — send us your original unit, we replace the failed components on the board and return the same unit, so it keeps the coding and security data already matched to your car and needs no programming (24-month warranty). Replacement — a brand-new unit with data transfer included; your original still has to be sent in so we can copy its coding and adaptation data across (12-month warranty). Both usually turn round in 1–3 working days.

Not sure the TCU is the cause? The symptoms and the fault codes we see on this unit are listed under Common Faults. If your codes differ, send them over before ordering — if the unit turns out not to be faulty you only pay the test fee and return postage.

Which vehicles does this TCU fit?

This unit is used across Audi, Seat, Skoda and Volkswagen. Check your exact model and year under Matching Vehicles, or compare the number printed on your own unit with the part numbers listed on this page. The same hardware often appears under several part numbers — call 01884 798090 if yours is not shown.

Prefer not to remove the unit yourself?

Choose the on-site option and bring the vehicle to our workshop in Uffculme, Devon. We remove, refit and road-test it before you drive away, usually the same day.

Frequently asked questions

Should I choose repair or replacement?

Repair is the usual choice: you get your own unit back with its coding intact and a longer warranty. A replacement makes sense when the unit is beyond economical repair — it is brand new, and your original still has to be sent in so we can transfer the data across.

How long will I be without the unit?

We work on a 1–3 working day turnaround once your unit reaches us, and it goes back on a tracked service. Ask about on-site fitting if you need the car back the same day.

My part number isn’t in the list — can you still help?

Usually yes. The same hardware appears under many part numbers. Send us a photo of the label or call 01884 798090 and we’ll confirm before you send anything.

What warranty do I get?

Repairs carry a 24-month warranty and replacement units 12 months. See Returns & Warranty for the full terms.

Will the warning light go out after the work?

Yes, once the unit is refitted and the stored codes are cleared, provided the fault was in this unit. If a related wiring or sensor fault is also present it has to be fixed separately — we tell you what we found.
