    I have a 52 plate C230 auto. Warning lights are on for ESP,BAS and SRS. I have checked front fuses (main box & side) and all appears to be fine. It is also stuck in P -although the AA mechanicic showed me how to free using screwdriver and lifting the coin holder until fixed. Any help would be much appreciated and wonder if the two problems are related.

    Change the brake lamp switch that sits on the brake pedal, about £12 and easy to do, you will have to remove the kick panel to get to it :D:D

    Electrical Problems

    Many thanks for the advice. Also noticed a warning that a rear brake light is out also. Is this also why gear is stuck in P?

    Yes the brake lamp switch can kill the speed signal in the BAS ECU, a very common fault

    ... and the solenoid doesn't release the gearlever lock unless it detects that your foot is on the brake pedal.
