Well recently my A4 1.8 TQ (150) B6 doesnt feel as nippy as it once did. Im a bit of a noob and just wondering what things I could check myself before taking it to the garage. Im thinking air filter and spark plugs. Would these effect performance? Also whats the best way to clean the MAF? I have a guide on cleaning it with a cotton earbud but read somewhere here about using brake cleaner, is that safe?
Something Ive noticed with this car is it seems quite noisy anywhere from 80mph+. Im not sure if this is engine noise or road noise or perhaps its just how the quattro sounds. Can anyone tell me what kind of RPMs I should be doing at 80mph.
Sorry if Ive asked any stupid questios above but like I said Im a bit a noob.
Cheers for the help.
