    Hi all,

    First post, and as usual it's for trouble.

    I have a C200 diesel (55 plate), and it's recently had a the MIL come on. I've plugged in the trusty old code reader and it's thrown three codes up. Any help in interpreting would be greatly appreciated. Car seems generally a bit low on power, and was for a while before the lights came on.

    Codes are:
    P0107 - Manifold absolute pressure/barometric pressure circuit low input
    P0472 - Exhaust pressure sensor low
    P0698 - Sensor reference voltage "C" circuit low

    I can find some info on what the first two relate to, but the third one has me completely foxed. I'm assuming, seeing as they were all there when I plugged in the code reader, that they're all related to the same issue that's triggering the MIL.

    Any comments/help greatly appreciated!

    Gary

    It occasionally going into limp home mode now. Booked into MB Warrington for Thursday, any tips prior to then greatly appreciated! I have a hunch it's a sensor issue rather than an actual problem.
