Engine control module from a 2007 Mercedes-Benz E350. This was carefully removed from a vehicle that ran well with no check engine light on and is in perfect working order. The case and connectors have no broken parts, but all four mounting pegs are missing. These can easily be transferred from your current ECM during installation. The images are of the actual item you will receive. 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. Fits 2006 Mercedes-Benz CLK350, 2007 Mercedes-Benz C350 and 2007-2008 Mercedes-Benz E350 with part number 272 153 32 91 ONLY.
