hi ive been looking round trying to find info on my 2002 A4 B6 1.9TDI quattro. i thought all quattros were the haldex system but now i find theres a torsen system too, but I can't find which version mine is. can anyone tell me haldex or torsen? i also thought it was a permanent 4wd but im reading some are 2wd with the 4wd kicking in when needed. aargh! sorry, very confused newbie!
