    Im too sure but could it be a collapsing hose to the turbo?
    I think its happened before on tuned cars?
    Or maybe a faulty DV?
    Im sure other members will point you in the right direction. [img]/ubbthreads/images/graemlins/beerchug.gif[/img]

    My car goes quickly from 3000-4500 then i think there is a little flat spot. In higher gears you notice it a lot more then in lower ones. I think when you floor your car, the boost is higher for a little time?

    Is this true?

    The coilpack delivers the electical charge to your spark plug.

    Yes there is a slight flat spot on a standard S3 about 4000rpm before it picks up again.

    Diverter Valve (DV) - If this goes u will know about it, i was informed i prolly wouldnt get out of 3rd if it went.

    Coilpack - Again u will know if one of these go the car will only be running on 3 cylinders if one goes so it will be running real ruff and u will know there is something wrong.

    Air Intake Hose - Flat spot about 5000rpm could be your air intake hose collasping but it is usally a problem with chipped cars (is your car chipped).

    Wastegate - I currently have a problem with my car its got a flat spot about 2500rpm and then it picks up about 3500rpm but not properly, it has been diagnosed as the wastegate is sticking.

    Mass Air Sensor - Not to sure of the symptoms.

    But i would say the Air intake hose if it is chipped.

    Are u getting a fault warning light coming on.

    Is this something the dealer could do? without spoting the chip?

    it going to be really difficult to explain to the dealer how u have managed to get the flat spot at that point, especially if u do not want to declare the chip to them. My dealer is great, he knows i have a remap and i just explained the problem i was getting and a possible way to fix so he did it.
    Does it do it all the time??

    Well no, only when I been hoofing for a bit, then not only do the brakes fade badly (and smell) but the flat spot is quite bad. Actually it's only been in the recent heat that it's been as bad.
