We repair the Mercedes C-CLASS Gear Selector. Send us your original unit: we repair the module’s electronics and switch mechanism, then test it through its full selection range before it goes back to you — usually within 2–5 working days. You get your own unit back rather than a replacement, so it keeps the coding and security data already matched to your car — no programming or dealer visit needed. Every repair carries a 24-month warranty.
Not sure the selector module 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.
This unit is used across Mercedes. 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.
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.

No. This is a repair, not an exchange — you get your original unit back, so it keeps the coding and security data already matched to your car. Refit it and clear any stored fault codes with a diagnostic tool.
We aim to complete all repairs within 2–5 working days. Should a repair take longer, we will contact you with an update. It goes back to you on a tracked service. Ask about on-site fitting if you need the car back the same day.
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.
Repairs of this unit carry a 24-month warranty. See Returns & Warranty for the full terms.
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.

Seeing different codes, or not sure the selector module is the cause? Call 01884 798090 — we’ll check your codes and symptoms before you send anything.
