    Evening all,

    have done this to my C270 and it's great!

    What is it you ask?

    Resetting the gearbox.

    Does anyone know if this can also be done to a 57reg A180 Auto??

    Have tried the same key in/foot down/foot up/key off/2 minute wait procedure that works in my 203 but never really noticed a difference.

    Anyone help?

    Cheers
    Tony

    It doesn't work on any car.

    The reset?

    Seems to work on some but not others - definitely worked on my 270 though. Feels like you've fitted a new gearbox!!

    It resets the accelerator pedal memory, not the gearbox.

    I believe it resets the throttle position sensor which works with the gearbox and 'learns' your style of driving - that's what I've learned so far anyway!

    Surely by its very nature a CVT based system shouldn't have to 'learn' your style of driving?

    Can you elaborate on the proceedure - I might give that a try on my ML270 to see if it will liven things up a little.

    When you say key in - do you turn it on at all and how far?

    Procedure as follows -

    Key in, turn to Position 1 (first 'click'!)
    Press accelerator to the floor and hold for a count of five
    Release
    Turn key back to off position but do not remove
    Wait a minimum of two minutes then drive as normal.

    I believe that it resets the throttle position sensor and/or the gearbox logic so that it 're-learns' your driving style.

    Definitely worked in my 270 - certainly wasn't just placebo effect!! Felt livelier and more responsive - quite sluggish before.

    Good luck!
