DSG jumping out of gear on take off

[logoris]

Read the entire post had the same issue as OP, Had it at the dealer numerous times, nothing came of it was told it was normal operation, finally tuned the trans to try to fix it my self, thinking maybe more clamping pressure might help, but obviously not, the display going from d1 to d to d1 and the pedal briefly unresponsive finally gave me something to go off of. This issue would also happen no matter how gentle I was letting off the brake

finally got fed-up with it after having my 19 gsw for almost 4 years and it doing it for 3. I had found a known good transmission of a local guy that swapped his alltrack to manual and didn't have this issue.

I took it into a local performance shop Pfaff tuning, when they first felt it and saw the video they said that it 100% is not supposed to happen. It is certainly a mechatronics unit issue.

As I had a whole transmission to put in that had lower miles on it, we decided to put the whole thing in, flywheel and trans fully assembled, they are actually testing it one more time in the morning , but they say its driving like factory again, and they cannot replicate it any more.

I'm confused. Did you buy a new DSG and Pfaff installed it for you? You're probably out of warranty now so it's not cheap.

VW wasn't helping, so I started looking for a trans then found this guy that had the whole dq250, with the bevel box and flywheel for $1200. it seemed like a good deal. For the install of supplied trans was only 2100 including fluid and hardware

PFAFF did some diag first and determined that the mechatronics was going, so we decided to put the whole trans in instead of trying just the mechatronics unit.

Had extended warranty but since vw wasn't helping and I tuned it to try to fix it before I knew what the real issue was, but the upside is it did not flag so I may actually have powertrain with the new trans.

Pfaff is doing final test drive today so hopefully I will have it back today, They told me yesterday that the issue seems to be gone, they just need to test a couple more times.

Fwiw, the mk6 dsg failures were all mechatronics related, and the issue was more prevalent in Europe it seems. They typically swapped the control module to resolve. Their symptoms were different though, with failure to fully engage and several shifts being very hard (not just off the line).

Got the car back, it honestly feels like new, will update as I get mileage on it

If this turns out to be mechatronics related like the mk6, it makes a good argument against dsg. The module swap would still have been easier than the trans swap.

I jumped ship to a different platform, and the dsg was one of the bigger reasons why. It was great most of the time, and fast, but at times it was incredibly annoying for city driving. With two kids, in the back it was no longer worth the hassle. I still miss that car though.

Mechatronic issues are rare on the MK7 but definitely still possible. Unfortunately mine also has the issue and we never fixed it because the dealers couldn't replicate the problem while my car was under warranty. I knew a dealer mechanic who said he could fix it for me under warranty but for whatever reason, I never reached out to him again.

I would check with pfaff tuning, I did leave it there for about a week before it acted up infront of them, and after that they were able to replicate it often, specailly if you take it in the near future they will still remember the issue.

down side their rentals arnt cheap, it was about $50 a day and so all in it came out to about $900 in rental.

but the installation of the trans was only $2160+tax and for a mech unit swap was $1000 + the part

I don't have warranty anymore and I'm not interested in paying $5k for a new DSG as I wouldn't buy a used transmission. The D1-D-D1 issue hasn't gotten worse over the past couple years so I doubt my transmission is blowing up anytime soon, especially since I track it and it's still working fine.

That is fair, mine was getting pretty bad, my girlfriend had it happen every day to and from work and it would be unresponsive for almost 2-3 seconds each time. Now with it fixed, it feels like some was seriously wrong before

That's a daily occurrence with mine, especially with engine start/stop.

One thing in this now v. long thread....not eveyrone is having the same issue even if the symptoms are similar. After 6 years/110K mi/beating on mine, this issue has been basically hit/miss/rare so a failed mech is not why my issue is happening. If this is every single time you take off, sure, you have something going on.

It wasnt every single time, but when it is cool out it is super predictable, it would show d1>d>d1 and the throttle goes unresponsive in the this moment, I have been able to stomp the gas pedal 4 to 5 times on a bad day before it would react again. during the summer for me it is almost completely gone but when its cooler out still above frost it happens, it never happens when its up to operating temperature, its been happening for us winter fall and spring for almost 70k km.

what you described in the first post is exactly what happened, just we didnt have a tune until I thought more clamping pressure would help but it did give me the gear indicator to show it changing. Which obviously didnt help, I also replaced the brake switch as it seems related to the brake pedal.

When they were working on it, they said it would mech unit getting incorrect data or adapting data incorrectly, so your thought of it being a brief safe mode to stop a stall, is still accurate, something is happening that it doesnt like and it seems like a panic.

I just get this so rarely anymore, once in a while and I find when that happens it will do it more than once on that drivce. I also have likely done a bit of muscle memory training to always move off the brake a tiny tiny bit first for the clutch to grab then release it.
