13-15 Mercedes C300 C350 E350 SLK350 ECU ECM PCM Engine Computer 276 900 50 00

276 900 50 00 engine control unit. These were carefully removed from running vehicles with no check engine light on. The case and connectors have no broken parts. You will receive one ECM in similar condition as what is pictured.

This ECM has been unlocked. This will still need to be programmed to your vehicle during installation. But since this ECM is unlocked, the programming process is no different than installing a new ECM. This makes finding a repair facility to program this part much easier as it eliminates the hardest part of the pre-owned ECM installation process. Please confirm that your repair facility has the hardware and software to perform this procedure before making your purchase. We recommend authentic XENTRY software with any compatible hardware.
