Oil can leak into the engine wiring harness from the camshaft sensor. If the leaky sensor is not repaired, the oil can migrate through the wires and possibly damage the engine control unit. Have the sensor and harness checked regularly.

    Oil leaking into wiring harness from CAM sensor I am told by my mechanic today. I did find online however that this is a RECALL issue for this car and I am now taking into the Benz Dealer for repair and hope the Engine Check light goes off. This car has run perfectly since day one and really doesn't even appear to be running poorly with the light on. I run it on synthetic Mobil One 5-40 and change it regularly.

    Oil leaked on to wire harness. There is a service campaign for this issue: 2009100001.
    Mercedes Benz dealership fixed the problem. Material and labor was about $6000. at no cost to me.

    I went to dealer for the recall (California) the replaced everything harness computer magnets the car had the same problem camshaft solenoid timing. They charge me 350.00 to see the chain tensioners that were perfect then they wanted to open the chain covers for 2800.00 I told them I didn't trust them, did some work I found they didn't replace the timing sensor intake on left side of the engine I ordered the part one bolt and replaced it, check engine light finally went out.
    Went back to dealer and they gave me back the 350.00 they charged me to see the tensioners and the chain.
    Don't trust dealers
