    my s3 has been chipped, it used to feel quick but now it doesnt i mean itsnot where i got used to it it feels and is nt as quick up against over car like bmw 330i, ive had a quick look at the hose,s and everythink looks ok no splits or any thing, the only problem is i have dirt/oil build up around the dump valve the two hoses that are the same size.

    I'd replace the dump valve (if standard and service if not) and if you can get the MAF sensor checked using VAG Com or just replace it anyway if it's old and see if that helps.

    If there is a lot of oil in the pipes going to / from the DV that could indicate a serious problem with the engine / turbo, as long as it's not much though I wouldn't worry.

    have you taken the pipes off the dv and checked if there is oil in the pipes? it could possibly be the oil seals and bearings in the turbo are shagged

    The MAF is around £80 from Audi on an exhance basis from memory, for VAG Com I'd get the cable off ebay and have a play with the free software to start with.

    The oil may not be from the Turbo, so before you start spending money if there is excessive oil present make sure you find the correct cause, I think a little oil is always to be expected in the whole of loop from the turbo back to the intake to be honest.
