    Ok.. i cleaned MAF with IPA, and reset the ECU (disconnected battery for about 20 mins) and then put everything back to normal... Went down to petrol station to get petrol (obviously) and it was not idling correctly!?! What the hells going on? It just feels slow, but the turbo is working and its drives ok apart from idle (intermittent) and lack of power.

    all ideas welcome.. santa pods 3 weeks away and need it back to its normal self!!!!

    if yours has a throttle cable not dbw, try removing the throttle body and cleaning out around the butterfly flap thingy, mine had same simptoms as yours- all i did was clean the hole throttle body inside the black plastic box as well, this sorted it out ?? i belive somtimes the stepper motor in the throttle body gets stuck or dirty...

    Rich,

    Thats a good suggestion by matt, re: throttle body, that was done on my non-dbw A3 1.8T at one point. But I think that was before they realised the true ****-ness of the coil-packs. If its not idling correctly, my first guess always would be coil pack.

    Uneven idling and loss of power can be caused by so many things....just another one for you is the main thermal sensor on the engine, as this can casue the ECU to believe the engine is running hotter or colder than it actually is....BUT I think you should look at the easy items first such as the throttle body, fuel filter, MAF etc. etc.
