Mercedes-Benz · Advanced diagnostic & programming services
Mercedes-Benz diagnostics, coding and programming.
Mercedes-Benz electronics are deep and tightly linked. We diagnose, code, program and configure Mercedes control modules on supported models, and do key-related work where the car's system allows it.
On cars with the FBS4 immobiliser, we do all ECU adaptations, on new or used units.

On Mercedes-Benz cars with the FBS4 immobiliser we can do all the ECU adaptations, whether the unit is new or used. The one thing we can't do on FBS4 is spare keys. Mercedes key systems vary a lot by age, so phone with the model and year and we'll tell you which system your car has before you bring it in.
Common Mercedes-Benz jobs
- Car won't startThe key isn't recognised, or the ignition doesn't respond.
- Several warnings at onceOften a network or power supply fault, not several failed parts.
- Used ECU fittedA second-hand ECU has to be adapted to the car's FBS4 immobiliser before it will start.
- Adaptations after repairSystems that need to relearn after parts are replaced.

Dealer-level work, without the trip to the dealer.
We've invested in professional Abrites Full Protocol and TOPDON Phoenix Max diagnostic and programming technology. It lets us carry out advanced electronic procedures on supported VAG, BMW, MINI, Mercedes-Benz, Porsche, Renault and Nissan vehicles, here in Mountain View.
Services are subject to vehicle model, year, control-module type, software version and system compatibility. Phone with the make, model, year and VIN and we'll confirm before you bring the car in.
Questions we get asked
Can you fit a used ECU to my Mercedes-Benz?
Yes, including on cars with the FBS4 immobiliser. We do all FBS4 ECU adaptations, on new or used units. Phone with the part number before you buy.
Can you program Mercedes-Benz keys?
On some models and key systems, yes. Spare keys for cars with the FBS4 immobiliser are the exception. Phone with the model and year and we'll tell you straight.
Can you replace and configure a Mercedes module?
On supported models, yes. The module is programmed, coded and adapted to your car, and we scan everything again before it goes home.
Do you service Mercedes-Benz too?
All makes are welcome in the workshop for servicing and repairs. See the home page.
Another workshop? Send us the programming job.
If you don't have the equipment to finish a coding, programming or key job, we can do that part for you and hand the car back.
Mercedes-Benz electronics fault? Call us.
Phone with the make, model, year and VIN and we'll confirm whether it's a job we can do before you bring the car in.
