Hi i was looking into buying a b6 audi s4 and i was wondering what problems cpuld i possibly run into since ive heard that these have problems with using up oil and problems replacing the timing chain.
its not just the timing chain, its the internal parts that hold the chain too. audi went cheap and used organic parts that decompose after a while and that's really what causes the timing chain to fail.
other than that, a lot of oil leaks/burning excessive oil/terrible gas mileage
MAF sensor usually gets dirty, that throws random CELS's...
the catalytic converters go bad in time too, especially if your running lean.
