The dsg gearbox on my edition 30 has developed a loud clunking sound when changing down from 3 to 2 gear, when the engine is de accelerating to come to a standstill.
And after this clunk has happened it takes a while to re engage before the car moves with properly, like a delay.
Its also jerky when the box is changing gear between first to second gear and to third sometimes, so im thinking there is a problem with the gearbox mechatronics but the car is out of warranty by four months.
Im also running revo stage 2+ and stage 2 dsg software, any ideas will be appreciated.

If you have VCDS (vag-com) or someone near you. You can try a DSG reset. Not that hard but all info can be found on ross-tech.com
It would pay to do a DSG gearbox flush too. IF it's still not better after that. I'm afraid you will be in for a replacement of a mechatronics unit.
so expect around £4000 ish I'm only guess at this stage. In New Zealand they are $10000NZ for an exchanged unit.

I would do as said try the reset/re-calibration and depending on distance since fluid service consider that as well since it will be a cheaper option. My next step in your case would be to go back to the revo dealer that did the dSG software and get them to try re-installing, or dropping to stage one or stock software before spending lots of money on a new mechatronic. And at 4 month out of warranty if you do have a mech issue I would be thiking of temporary return to standard and see what good will gesture VW will consider!!!
-
I might get someone with VDCS to do a dsg reset, but wont that effect the revo software in the gearbox mechatronics?
The fluid was changed by VW about 3 thousand miles ago and this did not happen before they changed the oil, so i might try them and see if they can do anything and say it dident do it before. I might have to put the car back to stock first then try them.
-
I would put the stock dsg software back on, to see if its the map causing it.
Basic settings on vcds is worth doing.
I very much doubt anything major mechanical is wrong with it.
Edit...... Just read your post above :signLOL:

I wish I could have said the same, but from February this year till may this year. VW installed 4 mechatronic unit's in my mk5 TDI. Only done 50000km's by the time I was fed up and told them where to stick the car. Now drive a manual 6spd GTI instead. (funny thing thou, I want a DSG GTI now)
-
doing the basic setting reset wont affect your DSG revo map, all it does it put the fuzzy logic back to blank forcing it to re-calibrate the clutch positions and shift points, and start re-learning.
Certinaly worth a go before you have to revert to stock and start having discussions with VW outside of warranty.

Thanks Rich i will get in touch with my revo dealer who also has vdcs and get him to do dsg reset, before i try my luck with vw.

having experienced similar issues in my old ed30, my advice would be to remove all mod's before you approach vw for help
i was still under warranty when my dsg went wrong but running alot of mod's with stage 2+ and stage 2 dsg and they refused to fix it saying it was my fault for putting too much power through the box. i took it to vw hq and was told the same.
in the end I returned the car back to standard and I must say the dsg felt noticeably smoother. then before i traded it, It went for its 40k service and dsg oil change and when I got the car back I had no complaints with the gear box
if you havent had the dsg oil change then do that before you start resetting via vagcom, as they should do it as part of the oil change

I just had a DSG reset and it didnt cure the surging on my ED30. The Mechatronics was replaced and the invoice was £900 but that was paid by VAG as it s still in warranty . £4k ??

Sounds almost certainly that the mechatronics unit has had it.
Have you had any luck with VW?
Certainly becomming more and more common especially with mapped cars.

I was guessing at price mate. Vw parts appear to cost approx 40% of NZ's pricing.
So I took it from what vw had to pay on my dsg. Many a times.
If they are only £900 here i might benefit from ordering and shipping them to new Zealand. Would so be worth my while.
-
Hi it was £900 including fitting , sorry if it apeared rude the way i posted it .
-
Any updates on this one?
-
Got the car booked in this week for a dsg reset so i will update if that's made any difference when that has been done.
But i have been driving the car around in manual mode, since mentioned by another member and it has relay improved the gear change in D mode, but the loud cluck is still there.
Will try VW if the noise is still present after the reset.
-
Mine is clunking from 3-2 and 5-6 just had a new mechatronic for this and its no better and its made the other issues worse to. yet another trip back to VW in the new yr, joy
Can anyway link the dsg reset page from ross-tech as i cant seem to find it. cheers

hello everybody, i have just found this old topic. i'm not a gti owner, my car is a gof VI, 1.6 mpi engine and DSG7 gearbox. although it is not a very powerful engine :smiley: , nothing remapped or something, i have the same problem when DSG changes from 3 to 2, deaccelerating and after, that lag when accelerating again. my car has still warranty and this problem begins to appear from about 5000Km (currently 11000). all the settings the technicians tried (adaptations, resets, sw upgrade) were not helped much. lastly, they did some settings (didn't want to tell me what :fighting:) who reduced the problems almost totally, but after a while i'm back to its original problems. i need your advice please, the only solution is to change the mechatronics? the technicians are very scared of this operation, and I saw some other resolutions from HQ that would be a normal operating state... this happens only in Romania, or everywhere else?
thank you, i appreciate any reply, sorry for my english :innocent:

Yeah replacement of Mechatronics is your answer. Sorry to report, (got info from VW head office in New Zealand) that the first gen 7spd DSG (2008-2009) where by far the worst for failing.
It appears most of the issue are actually heat related more than anything else.

Not all problems with the DSG are down to the Mech unit. indeed he has the newer version which is quite a bit different so it's wrong to make assumptions. Just take it to a garage that can fix the problem. If your garage is scared of changing one out then dont use them. :happy2:

Lol, yeah I know that. but as described above. that was happening on my DSG one of the 5 Mechatronics replacement units. Replacement was that issue's cure.
But yes, doing a DSG reset and or oil change can sometimes fix the issue's too.

This is all going wrong!!
If you have a fault with you dsg box or it makes noise doesn't mean its mechantronics is chuffed it,
The mechantronic part of the box works on valves and uses the fluid to Manover the box, the dsg system does "as mentioned" learn your driving, however as with all things the when the values exceed a limit (the feedback from the box to the mech) they sometimes loose sync and the box will sill operate however will be notchy as it's just engaging gears how it wants. The down side to this is that how the dsg box mech works (by firing oil using valves i small holes into the dsg box) can make things worse if you have other problems (like low fluid,filter clogged giving you surges of notchy changes)
The dsg reset should help and give you a starting point, my first point of call would be to just change the dsg oil and filter £169 at the moment, this does require us to use the 50/52 to run the box up to temp and tell us how much fluid is in there and it would make sense and it's already on a test plan to do basic settings on the box, irratic gear changes genrallg mean a deffo mech fault and the mechtronics is what starts the change :)
This may not sound to "explained" I allways find it hard to try to explain things like this
Cheers

thank you all for replying, in my first post i forgot to mention other sporadic symptoms: a couple of times driving on highway at 130/120 km/h, at about 3000/2800 rpm, in the D7 gear, suddenly it begins to switch D7-D6-D7-D6 ... for about about 15-20 seconds with a frequency of about two changes per second (rev counter indicates +/- 200 rpm), without anything changing, constantly accelerating, no sudden wind, without any slope or ramp. this kind of gear switching was happened another 2 times, after beginning to move from stand still, switching D1-D2 about the same rate, while slow accelerating, the car tends to stop. even though I seriously pressed the gas pedal to avoid disturbing traffic ...
again, sorry for my english :innocent:

Now this sounds mechatronic related, the best thing to do is get it booked in, take it in the night before so they can drive it from cold.

hello everybody, long time no post... but meanwhile nothing happened. except some mails exchanged with the factory. till now.
finally, the technicians changed my DSG7 gearbox (all of it, mechanics + mechatronics + clutch discs) with a new one, sent from the factory in the last month of warranty... but... surprise!!! the old MAIN problem is still there: when DSG changes from 3 to 2, deaccelerating, sometimes the car is clunking again! (my other problems described two posts ago seems to be soved for the moment, but time will tell)
do you have any ideas about this problem? could this be due to some engine problems? I am very confused and disappointed about VW...
thank you, i appreciate any reply, sorry for my english :innocent:

You could have problems with VW when they plug in and see that you have a DSG remap, may not touch it or overwrite your remap.
