Hi.
I have a 2005 Audi A3 2.0 FSI with tiptronic auto, which I have had from new, and now has 60,000 miles on the clock. It has caused me very little hassle but in the last couple of months it has developed the following problem:
After about 30 minutes of driving I get a significant ‘thud’ changing down through the gears, particularly from 5th to 4th and from 4th to 3rd, but occasionally in others. When very bad it also delays very slightly and then ‘thuds’ into gear when going from from neutral to 1st. There are no warning lights, and no other symptoms of any kind. It is so bad you and your passengers think you must have hit something.
Audi (Wimbledon) investigated and found nothing wrong, and initially suggested a gearbox oil and filter change which they did. This generally made the gear changes smoother but had no effect on the problem. They now tell me all they can suggest is a glycol test followed by a new gear box for £4,500.
A search of the forums comes up with lots of similar sounding problems deriving from the Mechatronic unit, but as I’ve not got a DSG I thought I don’t have one.
Does anyone have any thoughts? Any suggestions gratefully received.
Thanks,
Alex
