Has anyone else experienced the following problem that doesn't always show it's self but I think it could be getting worse. When I pull away in 1st (Auto or manual mode) sometimes the clutch feels like it engages to harshly and nearly stalls the engine. Then the car sort of lurches forward a bit like a learner driver in a manual car. As I said it does not always happen but is annoying when it does and sounds harsh on the transmission. The gearbox was serviced at 40k by VW so the oil should be good.

All other operation of the box is smooth and just like the one my wife has in her GT tdi and I can't fault it.

My car is also experiencing similar problems. I recently took it to the dealer twice! and they claimed the issue was with the Mechatronics unit. First time they changed the unit (no improvements), so the second time they "flashed" the unit to update the timing but with no real improvements again! So now I'm trying to find a manual gearbox or file a claim for them to give me a new dsg gearbox under warranty.

The issue usually occurs around 2-4k rpms with mild throttle. There is a hard thump and pop into the next gear, only really discernible in 1st-2nd-3rd gears.

Speaking of which if anyone in Europe (or UK) can give me the part number for the Manual gearbox, i would appreciate it! :help:

My guess is the clutch packs. engine/trans mounts need replacing, but somehow the service people are being hard asses and do not feel the need to do the repairs.

I assume you have already gone through the full DSG reset\basic settings and re-learn procedure a set out in Vag Com\VCDS?If not then that is one sure to do.

My DSG is quite harsh when the engine and gear box are cold, if I go to fast straight off the gear changers are harsh, but when its warmed up there are no further issues, its been like that in the 4 years ive had the car and the gear box has been serviced twice in that time.

Does it have hill-hold? Sometimes mine a bit jerky to release the brakes when just setting off on a hill. If you wait the 2 secs for the brakes to release on their own then it'll pull away smoothly.

Guess its for all DSG boxes, mines the same when cold, worse when stone cold. Also it feels sluggish too.

Once warmed, no harshness at all.

It's all in the technique - release your foot slowly off the brake and as soon as it bites nail it!

I haven't but will do some research and then plug in thanks for the tip.

The problem seems worse when the gearbox is warm to hot and when cold its faultless. To me the fault feels like the clutch for first is more worn and the gearbox loses the reference for biting point so when it engages it dumps the clutch almost stalling the engine.

I have a very similar jerky-ness with mine, it's fine until it gets driven hard for a while when the engines warm, jerks in gear changes & also when I'm stationary & put it in drive. Any ideas what this could be, is it mechatronic unit issues?

Tried all sorts of things to try and understand the cause. Foot slowly off the brake, gas it, left foot brake and increase rpm etc. nothing cures it when it happens. Even when warm it's not guaranteed that it will happen. :(

CCT, where are you based mate? I'd be willing to do the DSG reset and calibration for you if you fancy trying it.

I'm in Huddersfield.

I'm in Nottingham but do have a full copy of vag com. Just never done it before and don't want to screw something up. I'll give it a go on Saturday probably cod I'm away this week.

After having my mechatronics unit replaced twice, the VW service center replaced the clutch packs and now it grabs a lot better. Also the Transmission mount was changed and that fixed the engine rocking sensation.

Mind you, if you do not have extended warranty, just sale the car. Its not worth the cost to fix it with your own money. Clutch packs alone would have been 1200 US$ and another 1000 for labor. FFFFFFFFFUUKKKKKKK THATTTT :rolleyes:
