Hi all new to this page so sorry if there's already loads of threads about this iv had a search and can't find any... Anyway just got myself an a4 avant b7 2.0 tfsi and at first it was beautiful to drive no issues at all but as iv had it a little longer iv started getting a bit more braver putting my foot down and when doing this I'm noticing some crunching through the gears it's got full service history and always had gearbox oiled so iv ticked that off list so now I'm thinking it's synchro just wondering what costs and best paces to get parts thanks
