Mk7 Golf DSG Gearbox Issues, Questions and Discussion

[fung9420]

It happens to my s3 after apr stage1. More noticeable in S. I found that the lagging or pause become less noticeable or minimal with completely turning off ESC.
Have a try and share how u go please.

I notice this too with Revo Stage 2. Sometimes it hits the limiter, but mostly it just hangs. I think a DSG tune would be required. I think the engine is spinning up faster than the gearbox is expecting. Will try the traction off-off and see if it helps

Update: I fiddled around with the settings in the JB1 Map 6 by reducing boost levels above 5500rpm - and it has stopped the hang.

GTI DSG rough shift in manual mode 1st to 2nd

Hi all,

Just about to click over 5000km on the GTI Performance, and it's been great so far - I'd never have expected it to be such a big step up from the mk6.

One thing that has me perplexed - in manual mode from a standing start, about 1 in 15 (or so) shifts from 1st to 2nd jolt or clunk quite heavily during the change - it's audible through the chassis. This tends to happen at mid throttle positions - not launching it by any means.

It's only first to second, only in manual mode, and tends to happen at mid rev / mid throttle range (2000 - 3500 rpm). It's not traction related, and also doesn't seem to feel engine mount related (I have experienced the shuddering / tramp caused by launching the mk6 - it's not that).

It feels much like the clutch packs are switching too quickly, or the computer isn't reducing the engine revs to match 2nd gear - a bit like hard changing a manual without the clutch.

Any ideas?

I know the Mk5 and MK6 suffered quite badly from the soft engine mounts (in particular the mount under the engine) allowing alot of movement and transferring this into the cabin. Every tuning company was quick to release a engine mount poly insert to stop alot of the movement. This could quite possibly be the case on your car (there are several engine mount inserts on the market for the Mk7 already) and you are noticing it at those revs/throttle position as the car is creating a fair bit of torque at those revs.

Thanks for the response Lucas - I'm not convinced that it's mechanical. I expect it would have the issue every time at that load level, but it's only doing it once every 10 or 15 changes (maybe more), the other 14 are silky smooth as expected - the difference is chalk and cheese.

My Mk5 Jetta DSG turbo and Mk6 GTI DSG never had the issue I'm describing here, although they did have that tramp / shudder when really launching the cars at the edge of traction.

I've got the same issue on my car, MY16 GTI Performance. Same as what you explained and for me occurs about every 10 shifts in manual mode. Sometimes it happens twice in a row too. I've got a 034 torque mount I'm waiting to install so when I do I'll let you know if it changes anything.

Thanks Mike, I'll be keen to know. Have you spoken to VW about it?

[Danoman]

Sorry to hear about the issues. Have you tried taking it back to the dealer to check?

If I recall correctly, my MY16 GTI would do the same from 1st to 2nd very early on... Drove me insane! After trying various things, I managed to replicate the issue. Basically, if auto stop-start was activated + the engine turns off while you're at a stand still, on restarting the shift would be harsh - guaranteed. The solution was to make sure stop-start was deactivated when in manual mode. Never had that problem since.

Not sure if it's the same issue you guys are experiencing but I thoughts it's worth sharing

Just got back from a drive and experienced it again, I can confirm it does happen after the engine stops and then starts while in manual; shifting between 1st and 2nd. Haven't driven long enough to see if it happens with stop-start off though. Strange that this happens. Has VW released anything on this at all? Or is it just something expected for our vehicles?

[mjgriffo]

Thanks guys, I'll give it a try. If it's 100% replicable it's probably worth taking to VW.

Oh, and thanks mods for merging my new topic with this one.

[mjgriffo]

So, I can confirm what Danoman and Mikeau described, it happens after a restart from the stop - start system, and happens about 90% of the time in that circumstance.

Has anyone had any luck discussing this with VW?

MY15 to MY16 DGS Changes?

Hi guys,

Just drove a MY16 golf 92TSI DSG and found it was a completely different drive to my existing MY15 golf. It provided a smoother drive, was less clunky, had a lot less engine braking when applying brakes going downhill and also a lot less vibration at lower speed.
Have there been any changes between the DSG in the MY15 to the MY16? I've heard a rumor that they changed to wet clutches in the MY16 but I haven't seen that written/referenced anywhere. Have most of the DSG issues been ironed out in the MY16/MY17 models?

Thanks

The 92TSI still uses the same 7-speed dry clutch DSG it did before. Although there may have been minor changes to part numbers and software/firmware versions of controllers, the gearboxes themselves should be otherwise identical. What you're describing is not unusual of the DSG - it can be quite susceptible to 'bad behaviour' depending on how it's driven/treated and can become recalcitrant over time. If you've having issues with yours (inc clutch vibration), check out http://www.vwwatercooled.com/forums/...ad-112515.html.
