Hi,
I've owned my 2008 GTi for over 2 years now and bought it with around 39k on the clock. It's now done 76k.
I had the DSG service done when I bought it so at the correct interval. It's been great, mostly smooth and quiet and very well behaved.
Just recently over the last couple of months when the car has been stuck in slow moving traffic for a while and the engine is nice and hot it gets a bit jerky when setting off in first. It goes with a jerk/clunk and then feels like the clutch hunts for the biting point a couple of times before it gets to grips with itself and then its fine. Once on the move its fine and changes are smooth as butter. When it's cold it's really smooth taking off even crawling from a standstill it has nice clutch control and no jerking.
Since I noticed this I had the 80k service done a bit early and included the DSG box oil change. Didn't make any difference.
I then did the box calibration with VAGCOM as per this
http://wiki.ross-tech.com/wiki/index.php/6-Speed_Direct_Shift_Gearbox_(DSG/02E) (http://wiki.ross-tech.com/wiki/index.php/6-Speed_Direct_Shift_Gearbox_(DSG/02E))
again, no difference. Still plays up like a learner driver setting off in first when it's all hot.
I'm going to try the gearbox reset / calibration again tonight but am wondering if there are any parameters I could log to see if I can check whats going on with the gearbox when it's hot. I was thinking about clutch pressure being a good one to check but I'm more concerned about the clunk.
Could the clunk be mechanical wear of some kind and the hunting clutch just be a consequence? I'm thinking maybe gearbox mount or gearbox internal wear but I'm not sure how common these are on the GTi.
For what it's worth the gearbox whines a bit in first and second, you can't hear it normally but if you drive in an underground carpark with the window down it's quite noticeable. A forum search shows this is fairly normal.
Any ideas where to go next, the car is perfectly driveable but it's a bit annoying if I'm in real heavy traffic with passengers.
Ideally I don't want to send off the mechatronics unit only for it to come back with no fault found.
-
I assume the selection shows the fault only when going down from second to first and up from first to second with the second to first being the most noticeable for harshness?
If this is the case it will be faultless at normal temperature for up to two hours of driving then it changes to the rough selection mode.
-
Not in my case, selection between gears is fine.
The problem is setting off from a standstill, all the other selections are fine. No warning lights or fault codes either.
I've tried in D, S and Manual and its the same in all.
-
Since you've cleared that up its not one I've had so can't help you :happy2:
-
Could it be a sticking caliper?
-
Could it be a sticking caliper?
That's a possibility I hadn't thought of! I'll check them but I did change the pads and discs all round myself not so long back and the calipers were in great shape. Worth a look.
I've done the DSG reset again just now but it's fairly late here so no traffic to get stuck in. All behaved well on the half hour drive afterwards.
If anyone else has VAG COM could they check the output of the brake pressure sensor for me (under ABS measurement blocks). Mine sits at .5 ish bar when my foot is off the brake pedal and i'm not sure if that is normal or not.
-
Did you do the defined drive after as said on wiki? Then it can learn the adaptations and clutch pressures. Don't have to do it as will learn over a period of time but best time do it in one go.

I did, when I did the adaptation last night I followed it with the defined test drive exactly to the letter of the wiki. Thanks for the suggestion. I'm keeping my fingers crossed this 2nd adaptation run will cure it.
If anyone does get a chance to check their brake pressure with foot off the pedal I'd appreciate it though, here's a screenshot of mine.

Correct me if I'm wrong but I'm sure iirc the brakes were off when no pressure is applied and when you apply the brake you get a reading as I was messing around with vagcom not long back and checking abs brakes dsg in trans and the rest associated with out car.
-
Thanks, that's what I was expecting. The reading does go up if I step on the brake pedal but I was expecting to see zero rather than this reading when the brakes are off.
Anyway, drove it all day today with no issues so maybe the second attempt at the DSG reset has worked - fingers crossed :phew:
-
Good luck :smiley:

Hi Mate,
Just wondering how your DSG has behaved since? I have the exact issue with my 58 Leon FR Tsfi. I changed the oil thinking the consistency was affected when heated up, but made no change. The brakes sticking was a very interesting theory, so will be checking the resistance both before startup and Hot today. It drives perfectly if only short drive.
Thanks in advance!

No luck I'm afraid. I've driven it a fair bit this week and it's still playing up when it's been stuck in traffic for a while.
I'm looking to get it booked in somewhere for a proper look over before something goes bang. The gearbox whine in 1st and 2nd may be related, perhaps it is a mechanical issue with the box rather than a mechatronic or control issue and the jerking is just a symptom.
I'll get in touch with these chaps and see what they think, just need to sort some time to get it booked in. I've heard good things about them.
http://www.gearboxnottingham.co.uk/gearbox-dsg-repair (http://www.gearboxnottingham.co.uk/gearbox-dsg-repair)
Also just waiting to hear back from these chaps as they're a lot closer to me, although I've not heard any reviews about them.
http://www.staautogearbox.co.uk/home (http://www.staautogearbox.co.uk/home)
Other than that, I might sneak it in for another fluid change just in case the main dealer missed something or didn't do it properly a few weeks ago.
-
Oh and I've checked the brakes, not seized or grabbing hot or cold. Shame, it was a good shout.
-
Gutter. Mine seems identical to yours. It's been jerky when hot since I purchased 14 months ago. Was noted on test drive as didn't get to hot. It seems to have got worse now tho and does have a quiet whine. One other thought I had was the idle rpm, as that's higher when cold.

Thats the place i took mine with the same symptoms and straight away said it was mechatronics. They can refurb them for £850.
Mine got a brandnew one though through warranty think it was just shy of £1400. Good luck
-
I'm having similar symptoms with mine. car feels like it's misfiring after 40miles into driving and feels sluggish. going to do a runner flap reset and if that doesn't help then delete the fecker.

Which place did you take it mate, the Nottingham one or the other one? Did a new Mech unit fix yours?

Nottingham one sorry, Slaters garage is who it is very good to deal with. Yeah it fixed it and its so much nicer to drive. No looking like your nearly stalling when taking off and it also holds on hill starts.
Mine also was really jerky in reverse. It was apparently somthing to do with valve side of the mechatronics. Good luck
-
Thanks, I appreciate it. The cars been good to me for the last 2 years so I don't mind forking out for a mech unit.
I'll post up when I eventually get it sorted.
-
Checked mine yesterday, the brake pressure sits at about 0.35bar without any pressure on the pedal

Thanks An0NyMOUs, that's really kind of you to check it out for me. :happy2:

Well, still no progress.
No response at all from the gearbox place nearest to me. Next plan is either to get a local place to remove the mech unit for me and I'll send it to ECU Testing for repair or try Gearbox Nottingham (although that's likely to be a £1k+ bill).
I've also found this place who are a bit nearer in Essex. Might try and get them to look at it for me.

It's one of those annoying faults that you can live with but is making the car less enjoyable when its hot. I'm also thinking it's not going to get better and maybe will get much worse? Need to pull my finger out this week.

Nottingham place is £850 to remove and refurb your mech unit and change the fluid. With a years warranty on it.

I highly recommend Bristol Gearbox Centre, they also do collection of the car with you too.

Go for the Bristol place
-
Thanks all, I'm popping over to the Bristol place for a chat next week. Great info, I didn't know about them before.

I've read about the Bristol place a lot ans they are highly recommended as one of our members used then a few weeks back and he had praises all the way :smiley:

Well, a huge thanks for recommending Bristol Gearbox Centre.
I dropped in for a chat and after a test drive and full explanation of the gearbox workings and the cause of my fault they offered to do the work there and then!
£700+Vat for the Mech Unit Valve body replacement inc fitting. Done and dusted in a couple of hours while waiting in their nice comfy waiting room, I just had to wait a half hour for a vehicle lift to come free. They then took me on the calibration/test drive and made sure I was happy. Not sure what software they used but it wasn't VAG COM, it moved on at each step once it was happy the driver had done the right amount of time in the right gear.
Have to say, it's a different car. Pulling away in 1st or reverse is silky smooth either creeping off throttle or light throttle or on a bit of power. Gearchanges, although good before, seem smoother too. Very happy bunny here!
The diagnosis was spot on and very different from the try it and see approach of another place I tried (would have wasted £1k on clutch pack change if I'd taken it there).
They have a nice setup with a clean workshop, 4 vehicle lifts and a lab/workshop where the repair ECU's and refurb the valve bodies.
There were another pair in the waiting room with their Audi A4 which was done while I was there, a broken link in their ECU was the cause and this was solder repaired under microscope rather than replacing the ECU. They showed the owner the fault and let him watch as they fixed it. Great service.
Can't recommend them highly enough, and they really are experts in DSG, S-Tronic and Multitronic.
One very happy bunny here :) Sounds like a lot of money but it's really been the only spend it's needed outside of routine maintenance in the 3 years I've had it. They also put my mind at rest about my recent VW DSG oil change, the oil that came out when they dropped it to remove the unit was lovely and fresh.

Great mate glad you got it all sorted. Mine was night and day after i got mine back aswell.

Finally, if anyone wants a real deep explanation of how the 6 speed DSG works I found this online when I was looking for fixes. Bit geeky but it explains it all

Hey doylebros. Sorry to bring up an old thread but I have the exact issue on a Mk6 gti I’ve just purchased. Can you tell me what the issue was with yours?
-
Hello I'm getting the same issue in which I have a jerky takeoff especially when hot in both reverse and drive no fault codes are stored in the ecu I have done the basic setting a couple times to no avail flywheel is good with 2 or 3 teeth freeplay gearbox level is correct and fluid is clean the car drives good with no slips or bangs its just the jerky takeoff from standstill is this the warning sign of a worn mechatronic unit?
