Martin23 Posted October 22, 2020 Share Posted October 22, 2020 Hi all, I need some advice , I have terrible sound when my 3.0biTDI auto is a very low speeds or stopped with gearbox in drive or reverse. Car seems to perform ok other than this but I think It isn’t as fast when pushing. The grinding sound seems to be come through the air box on LHS of engine. I do need the injector seals done as well. I have not changed the gearbox oil as I was advised it was sealed for life. Car has 150k on it and is driven with spirit.

beemerboy9 Posted October 22, 2020 Share Posted October 22, 2020 ...and it does make this noise when stopped in neutral? Assuming no noise in neutral, then it might well be the clutches inside the gearbox. It might also be worth checking the engine mounts as well - if they are hydraulically damped, one might have leaked. Hopefully someone will be along with more suggestions.

Martin23 Posted October 23, 2020 Author Share Posted October 23, 2020 Hi there, yes it’s doesn’t happen in neutral, engine mounts I wouldn’t have considered I’ll check that out but I’m fearing the worst ! Quote Link to comment Share on other sites More sharing options...
beemerboy9 Posted October 23, 2020 Share Posted October 23, 2020 The reason I said engine mounts is that you said it smooths out as you go faster at which point the engine will not rock about so much. If it is gearbox, take it an ZF gearbox specialist. Quote Link to comment Share on other sites More sharing options...
