Product Repair Details

We offer a repair service for your Mercedes M271 engine ECU.  The w204 C class engine ECU frequently fails causing the engine to miss fire and store fault codes that suggest one or more coils are faulty. These fault codes will reoccur even after the coils have been replaced. Another common issue we see with this ECU is that the engine all of sudden refuses to start, this fault often won’t leave fault codes however the drive authority data in the engine ECU won’t display a status in live data. If your ECU suffers a drive authority data issue we will also require you send the ignition switch and at least one key.
Our service includes repair of all known issues, often replacing parts with higher rated components to ensure reliability of this ECU into the future. Most turbo charged Mercedes c180 c200 engine ECUs are repairable if the fault is caught early enough. In the rare case that your ECU is beyond repair we stock reconditioned exchange modules that can be programmed to your vehicle. All ECU repairs come with a 12 month unlimited km warranty.
