Gearbox or Flywheel issue???

[Louis of London]

Hi guys, i've just purchased and Audi A3 S Line 2L TFSI 2008 with a DSG box at 62,000. The car drives great but when moving off the breaks from stationary at creeping speeds, there is a judder/shake until I apply throttle to roughly 5mph. I have just fully serviced the car and gearbox at an Audi specialist garage but this issue still occurs. The Audi specialist garage say it's a suspected flywheel issue but not certain. My local mechanic garage thinks the whole gearbox needs replacing just by driving it 5 metres backwards and forwards.

Has anyone else had this issue? And does anyone have any idea how much the potential repair would cost?

Thanks!

A little searching would have revealed this topic from just yesterday.

HAHA! This is my brother who actually recommended me to this website. His is a manual as mine is auto and a different gearbox. would you seem to think that it is the DMF then too?

Ah, I missed the fact it is automatic, which does not have the dual mass flywheel. My own automatic A3 suffered what I describe as clutch snatching when starting from rest. Audi would not even admit the problem existed, claiming the take off to be normal when they tested it, and could only suggest a new gearbox, an expense I was not prepared to even consider.

My own internet research indicated the fault lies in the Mechatronic unit which controls the gear changing and which would have to be overhauled or renewed at great expense, so I tolerated the fault until I got rid of the car some years later. The general suspicion is that it is a design or manufacturing fault by Audi in early DSGs, hence their reluctance admit the problem's existence.

Sorry to be the bearer of bad news, but your options are limited. The best I can suggest is you consult a gearbox specialist who might know how to deal with the Mechatronic and only charge a small fortune, rather than the large fortune that Audi will want.

Hi you mentioned yours is auto yes it has a DMF and yes you can get the mechatronics unit refurbished for not to much money at ECU testing.

Cheers guys. Couple of questions... Cliff, how long did you manage to drive the car with this issue? did it not need instant attention?

Stevey, could you please elaborate what you mean by "ECU testing"? I googled it and many different things have come up.

I put up with the fault for the whole time I had the car, which would have been perhaps five years. My wife refused to drive the car because of it, whereas I tolerated the problem by adapting my driving. At the time it was too good a car in other respects to get rid of, yet not worth spending a lot of money to repair. Nevertheless it was a constant irritation and I am glad I no longer have to concern myself with clutches and gearboxes. Eventually it was the imminent need of gearbox repair and the price of diesel that prompted me to sell it.

If it is the clutch the bill will be quite steep, its not the parts its the labour,

Hi Steve, is ECU testing based in London? 

I took the car to a gearbox specialist yesterday and he said because the gearbox has just been serviced give it a couple of weeks for the new oils to work and see how it gets. He also said it could be the DMF on it's way out or it could be the clutch. My uncle said to try and see if it needs retuning to check if the correct amount of gas is naturally being applied without a peddle when in 1st gear or reverse. I have so many suggestions now and i'm just a bit lost lol. If you happen to be within an hours drive I'd happily drive to you and maybe you could give some form of diagnosis? i'm based in north London. Would that be an option?

Hi  I have found from experience that changing the oil and filters can turn the box into wonderful again or throw in age related faults, I agree with what the gearbox guy said as vary rarely the new oil can dislodge bits of matter inside the casing which will take time to settle again, in saying that even though you have lowish milage things deteriorate with age and with that in mind metal fatigue on the moving parts of the clutch on your vehicle is a real possibility which the previous owner was well aware of, thank you for the offer of travel to me but it would be an exercise in futility as unless I can get inside the box to measure the float tolerances on the flywheel I can only tell you what you already know, my honest opinion is that the clutch is the problem but common sense says you will have to replace the flywheel as well as they wear as a set.
