Ive seen this audi on craigslist for quite sometime. Funny I am reading about it here on the forums..

hahahha...
so if i got 160 to 170 on compression test ,am good.....how can i be sure that my turbo its leaking ,the guy said he had just replaced it a month a go

OMG dude. CHECK YOUR PIPING FOR OIL!!!!!!! If there is oil in there, then your turbo oil seals are no good.

i check my pipe and there was a lot of oil where can i buy a turbo

get a used K03/K04 from a part out

for some reason my car stopped smoking .no more oil residue inside the exhaust,the only thing i did was to clean the fmic

never mine started smoking again after a long trip....i guess am gonna have to look for new turbo

You're knowledge isn't sharp enough to keep going on like this. You need to use the google button and research how turbo chargers work (and engines for that matter) after you learn whats going on you can ask what you're doing wrong. However chances are if you take the time to learn the system you won't need our help.
This is BASIC stuff you're talking about.
