    Evening all!

    Battery failed the other morning, so had to buy a new battery.(2.0T FSI)
    Since I had it fitted the engine warning light has turned off (decat pipe, not had it mapped out yet) and its lost alot of power.
    Still drives perfectly normal at any other point until I open it up. Then it just feels flat.

    Any ideas? Or will it sort it's self out over time or when the engine warning light comes back on?

    Cheers

    Disabling power to the ECU for a period of time puts it into master reset.

    Your ECU will adapt over 26 miles to your engine running conditions.

    So yes as you drive, the ECU will adapt itself. Keep driving

    :)
