    EPC light is for the throttle pedal ect for DBW (drive by wire) cars... First thing to do in this instance is to get the car checked for fault codes using VAGCOM or another diagnostic tool to establish whats going on.

    Unfortunate fact of life these days as cars become more reliant on electronics... could potentially be the throttle pedal playing up or possibly the throttle body. A simple throttle body reset may help.

    If you don't have access to VAGCOM at this time then you can force a TB reset by disconnecting the battery for a couple of minutes...

    If you do that though, make sure you have any radio security codes handy and you will need to cycle the electric windows down then back up to reinitialise the one touch.

    Proper Englsh for starters mate :)
    If the light has came on get it logged with Vagcom for any fault codes and take it from there.

    I assume your own mistakes were deliberate? ;)

    Deffo get it on a diagnostic machine of some type mate. It could be a lot of things causing it.

    We could sit here all day and suggest you change every single engine part from the MAF to the giggle pin in the laughing shaft and potentially spend a lot of money chasing a problem, when you could find out directly what it is and get it sorted....

    Regardless if the light went off or not it should still leave a 'trace' of the fault code so should be picked up by vag-com.

    Can you get a picture of it up so we know what type it is - or, does it look like this:

    [​IMG]

    If so, this will not be causing you any issues, it is a longer lasting version of the standard diaphragm diverter valve fitted to the engine by Audi.
