Codes and descriptions we recognise.
ODIS, VCDS, Autel, Launch, Topdon and other scanners can phrase the same manufacturer fault differently. We match the DTC, VAG symptom number where available, controller hardware and fault meaning rather than one exact sentence.
The part inside matters.
Premium LuK / Schaeffler repair components used where the Bosch hardware matches the supported application.
We use premium, traceable repair components and automotive-grade materials rather than anonymous lowest-cost parts. The completed repair is backed by our 2-year repair warranty.
Bench checked before and after repair.
We confirm the controller identity, electrical function and relevant sensor plausibility on the bench. Final basic settings, adaptation and operation are confirmed after refitting to the vehicle.

Do not send unrelated gearbox parts unless we have asked for them. If you are unsure which controller you have, send a clear photo of the label first.

Send the fault details with the unit.
We repair the customer's original controller wherever possible. Same-day priority applies to units received before 12:00 noon on a working day. Repair prices exclude courier charges; the customer pays shipping both ways.
