Just would like to know if anybody has had a similar problem
Car was serviced about 6 weeks ago by VAGtech and I had the tiptronic gearbox oil changed at the same time (first time it's been done)
Since then the gear changes in Auto/Drive have been much smoother and consistent. However in Tiptronic mode it’s sometimes getting itself into a bit of a pickle.
If I drive relatively sedately changing using the tiptronic all is fine, but if I push on a bit with higher throttle and changing at around 3500 RPM it will go through 1st – 2nd and 3rd through to 4th with no problem but then when going from 4th to 5th it won’t hold 5th gear and immediately drops down to 4th indicated on the DIS, although it’s not actually in 4th but sounds like it’s running via the torque converter (revs too high for 4th at indicated road speed) if I try to change up again to 5th it won’t do it – DIS goes to 5 and then immediately drops back to 4. The only way to stop it doing this is to put it back into D and slow right down and it then seems to sort itself out.
I've booked it in with VAGtech next Thursday but just wondered if anybody knows what this could be and am I going to be looking at a large bill ?
I've had the car 8 years now and we love it but the last 18 months it has cost over £4,500 in repairs. A 3-4 year old 3.0 TDI quatttro avant C6 is looking more and more appealing...............
