Dealer-level diagnostics

Mercedes-Benz dealer-level diagnostics in Melton Mowbray

Mercedes-Benz XENTRY dealer diagnostics in an independent workshop — programming, coding, keys and software for A to Citan.

Mercedes-Benz diagnostics with the dealer's own system

We run the Mercedes-Benz XENTRY dealer diagnostics — the same system a franchised Mercedes-Benz dealer plugs into your car. That means we see every control unit, not just the engine, and we can do the jobs that a generic tool cannot.

XENTRY-level fault finding, SCN coding and module programming, service resets, AdBlue and emissions faults on cars and vans.

Models we see most

A, B, C, E, S-Class, CLA, GLA, GLB, GLC, GLE, Vito, Sprinter, Citan — and the rest of the range.

What dealer-level lets us do on a Mercedes-Benz

  • Program and code replacement control modules
  • Key and immobiliser work (SERMI — bring V5C and ID)
  • Software updates and campaign fixes
  • Guided fault-finding written by the manufacturer
  • Driver-assistance, steering-angle and sensor calibration
  • Service, adaptation and emissions-system resets

Questions people ask

Do you have the genuine Mercedes-Benz dealer diagnostic tool?

Yes — Mercedes-Benz XENTRY dealer diagnostics, the system a main dealer uses, at our workshop in Melton Mowbray.

Can you program a new key for my Mercedes-Benz?

Yes. Key programming is security-related work under SERMI, so bring the V5C and photo ID — see our SERMI page for exactly what is needed.

Will using an independent garage affect my Mercedes-Benz warranty?

No. Servicing and repairs to the manufacturer schedule with the right parts keep the warranty valid; we record everything on your sheet and in the digital service record where the maker supports it.
