My W212 has Keyless Go which suddenly failed. I cannot now open the door or start the car without using the keyfob. I have checked the keyless go fuse, number 46 as I recall, plus all the other fuses in the same boot fusebox.
Today I met a Mercedes Roadside service engineer and told him about the problem. He said that the problem would be that I needed a new Engine Start plug, the one that I have had to remove so as to use the keyfob to start the car. I have never seen any forum post that mentions this plug as a cause of Keyless Go failure. The plug looks a device that has no active internals but I could be wrong. Hope someone can help me?
