    Does the oil have a strong smell? May be gearbox oil leaking from the output seal?

    Mine did the same, it turned out the egr valve gasket was long gone and it simply started to let oil thorough, take your engine cover off, put your hand under the egr (where the bolts are) and if you have a lot of oil there then you have your answer. If so, go to audi dealers get a new gasket for 6 pound and put it back on, might aswell clean the egr when doing that. Could also be the rocker cover gasket?

    sorry I thought it was the left hand side of the engine. Mine does the same, its the intercooler pipe and you have rubber seals around them which are called o-rings. Roughly about 6 pounds each.

    I have bought the K&N lifetime filter ( made a big difference ) also some people tend drill the airbox however I havn't done so. Another thing to do is block off the egr valve.. and now I'm going to put on bigger brakes, as the standard ones are not made for this sort of power. I have bought new brake pads and discs before the remap and they were superb however after I have remaped the car I've boiled the brakes twice ( soft pedal, no brakes ) of braking too hard so for me S4 brakes are on the list to do soonish.

    Apart from these things I would recomend anybody remap the car, it's so much better. For the same fuel economy you get much more out of your car.

    This is the filter I got:
