    Ive had this on my estate since buying it which was 8 or 9 months ago. Whenever the kickdown switch is used the car will stop reving at 2.8-3k and the waring "EL. POWER CONTROL" is displayed. This will clear after the car is turned off and restarted. The only fault stored on DAS is "B37 (Pedal value sensor) signal is too high".

    I replaced the pedal sensor yesterday and the fault is the same. The fault can be reproduced when the car is in park too. But if full throttle is used, without engaging the kickdown switch there is no fault.

    Anyone had a similar problem in the past?

    have you ever tried disconnecting the battery? It sounds like the pedal values have gone up the swanny... never had this but have had a similar message with steering angle sensor and sunroof limit sensors...

    Disconnecting the battery for a few mins normally resets.

    Not tried that, but the faults have been erased on DAS. Its only when the kickdown switch is used.

    No, and just as well.

    Have you tried resetting the pedal full throttle position using what some people call the gearbox reset.?

    Not sure what you mean, the gearbox adaptations? If so, Ive not done that.

    Ign ON, press pedal tot eh floor and hold for 5 sec, IGN off keep holding pedal down for 2 mins, release pedal.

    Some people think this is a gearbox reset but it's just the pedal full scale setting. It's just a thought.

    Gave this a try today, and it made no difference, so back to the drawing board.

    Ill check out the EGR, but it seems to function correctly. As does the turbo, the car is not going into limp mode. THe message comes up, but once the kick down switch is released, the car drives normally. This issue is only present whilst the kickdown switch is depressed.

    I had exactly the same problem with my E320cdi estate, every time the kick-down switch operated EPC Error flashed up and virtually all power was lost. Releasing accellerator and depressing again (not as far as switch) restored power.

    Having put up with this for a few months due to a combination of a dealer failing to look at it during service when asked, and too lazy to get it back to the dealer, it actually fixed itself. That was about three months ago and it hasn't re-occurred!
