It's happening more and more often - almost 2 times a day now. Coming out of a turn, usually in 3rd or 4th gear, the car revs, but doesn't move. Almost got into an accident today because the car just sits there for a couple seconds..

Going to Audi with it - but who knows what will come out of that.

Anyone ever get this? Stats - 2011 dsg, apr stg 2 V2, ect.

Probably something wrong with clutch acutation. Mechatronics maybe?

Sounds like the clutch packs are slipping . I've seen this on Evo's with the dual clutch trannies and the torque is too much for the tranny to handle.

I had this issue...Audi ended up replacing the mechatronics. All good since.

I had this issue...started out like yours Fonzie then got progressively worse, to the point where I had no acceleration at all. It would rev up but wouldn't move. Took it in and the clutches were running way too hot. Audi ended up replacing the mechatronics - 2 weeks in since replacement and all has been good.

If your clutches are slipping, shouldn't it be consistent? Not just occasionally under specific conditions? Given how complicated the controls on the DSG are, it could be a SW issue.

Definitely would like to hear the Audi position on this one given your state of tune. Your car is the poster child for TD1. Let us know what they say.

Issue with Mechatronics, (Sometimes it just does not shift or engage); http://www.audizine.com/forum/showthread.php/348999-DSG-Gearbox-Malfunction?p=5004373&viewfull=1#post5004373

Fonz,Similar situation. I have DSG, and had 2 incidents.
1- Downshifted 4-3 in a turn, lost power and stalled.
2- Downshifted 4-3 making turn, go to step on throttle, nothing. Revs to 3k and nothing. I'm now coasting from turn. Depress accelerator multiple times before it wakes up and resumes as if nothing happened.
Dealer found 2 fault codes for G71 Pressure Sensor. Opened tech case and was authorized to replace G71 Upstream Pressure Sensor. Happened with 12,500 on odometer, now at 22,500 with no issues.
Of note, never had cel from these 2 incidents.
Good luck w it, keep us posted Fonz

I had a Multitronic B6 A4 a few years back and had nothing but problems with it. I'll always buy a manual whilst they still make them.

I hope you get it sorted. Does sound clutch pack related...

There aren't a lot of issues with the DSG in these cars. Most of the "issues" are normal behavior that people don't like sometimes. For example jerking when coming to a stop or the tachometer not reaching redline during hard acceleration.

No point in waiting really.. if you're going to get TD1, it'll happen regardless of when you go to service. I don't think the tuners will be releasing a fix anytime soon, since they'd mention it if that was the case.

If your car does indeed have an issue, you run the risk of causing more damage not repairing it.

Goodluck[up]

Has only happened three time and I might just ship my ECU back to get it's original flash back on it. Just waiting for free time.

The problem the OP is having (as well as others on this thread) are not those mentioned by you. I've read several threads about problems with the tranny that is not the quirks of a dual clutch but actual warantee claims and issues. I really don't feel like going through all the threads and posting them here either... but I konw I've read them.

Any APR dealer can flash you back to stock. No need to pull the ECU

Fonzie are you still under warranty? And still have the tune? If so, please report back as to how the dealer handles your situation.

This little DSG gremlin is the only thing that gives me some concern about TD1 right now. I'd hate to have to pay for a new mechatronics when this is clearly an issue even with stock cars.

I think you are possibly mixing this up with the common DSG problem of sometimes it doesn't know to go up a gear rather than down so it may take a second to get into gear. This is a whole different issue but it is part of the DSG characteristic. The difference here is Fonzie is already in gear and it is slipping. The other issues mostly when you brake going into a corner or slowing down then suddenly accelerate, the transmission is preparing to go down a gear but now that you want to accelerate the DSG tranny will get confused and it will take a second or so to make the change. In the mean time you accelerate and all you get is noise but the car is not in gear yet.

Not if you are V 1.0. And after it is back to stock I will need to send it back to them to get V 2.0 put on it.

The ECU will allow the stock file to be flashed even if it is locked because the signatures check out / match indicating it is a legitimate Audi file that the ECU should allow.

Wrong. You can have it port flashed to stock at any APR dealer even if you are V1.0. Since it is a stock Audi flash with the proper keys, the ECU doesn't need to be unlocked to flash it. I've seen it done. You do have to send it in to get any tune put back on, though.

I'd estimate the part alone in the $900-$1000 range. Labor, that's a whole other story.

So, the other issue of the transmission failing to get into gear and just revving up when you hit the accelerator is a known, normal issue that doesn't have a fix?

Man oh man,this makes me kinda weary in getting a (non Stasis)tune as I have a stock ECU and every once in a while I get a THUD or clunk when coming to a stop from the DSG 2-1 downshift[:|].Hope you don"t get this TD1 flag I keep hearing about as this would suck royally to pay out of pocket for this.

I'd say it's fairly well known. It has happened to me. Here's a similar thread:

http://www.audizine.com/forum/showthread.php/476369-Caught-DSG-in-neutral-while-driving-anyone-else-with-this-issue

Seems that for most people it doesn't develop (or hasn't yet developed) into something requiring a repair, but some have had to get a new mechatronics.

That's exactly what I just did. Reflashed back to Stock, dropped the car off for a final diagnosis. If they fix it under warranty, wonderful. If they refuse, I'll be GT-R shopping in a week. (half kidding..)

I too have ran it no problem for a couple weeks. It's the opposite that is bad - running stage II with the stock pulley. Well, not bad, but you won't meet requested load if you go WOT. This will be especially likely to throw a code on any 'V2' where REVO and APR are requesting a little more than maximum achievable load at WOT (GIAC seemed to be opening the J808 blower bypass valve in the logs I saw).

where did you go to braman or audi coral springs?

Fonzie@DipYourCar
06-07-2012, 02:27 PM
I didn't go to Braman.

So here's the update:

They didn't see any fault codes for Mechatronics - or anything tranny related for that matter. With that, they can't do any work on the tranny. They reflashed my engine, tranny and sport diff softwares. From what he said, it seems as if there were updates for all three (I was an early 2011 car). Instructions now are to run in stock mode for 2 weeks, and see if it continues. They were able to see that I was chipped/modded not from the ECU flash, but from the logs and memory of the car.

Now going to run in stock mode for a couple weeks and see if it continues. One good note is that my car right now (in stock mode) is still short shifting in manual mode in 3rd gear under full throttle - so it's good to finally know that isn't APR or power related.. it's just my breed of DSG.

Updates to follow.

It's interesting that you apparently didn't get TD1. So maybe the flash back to stock prevented that. But this "logs and memory" stuff seems to confirm what yourownhero was told by AoA in his thread on the T10 code. Ugh.

Had my 15k service done today and I told them I had aftermarket software so no ecu flashes please. They thanked me for telling them in advance so not to "write over my investment". I was like huh? I was expecting them to yell at me. No mention of warranty denial or any T codes anywhere. The tech said it wasn't a big deal at all. Maybe they were clueless.

The funny thing is he said all my previous VAG codes were erased when they updated all my software.. but when I got the car back - they were still there. Not sure what happened there. The car right now was running ok - it's still shortshifting in M mode (even in stock mode) which bums me out - but the DSG hasn't slipped yet.

The car is back at the exhaust shop, which some people may want to see the results from. I'm having an x-pipe built in DIRECTLY after the test pipes. Not down the stream like most or old x pipe placement, actually between the front center muffler and the test pipes. I'll post pics - this should be a really interesting option for those of us with test pipes/headers or who want the x pipe up close where it's most effective.

Will keep updated about the DSG

I just dropped off my 2010 for DSG issues. This is my first post (Hi Everybody!) and figured I would chime in on the issue. Here's the details:
Car: 2010 S4 DSG
10.5k miles
Purchased CPO May 2012.

Symptoms: When car was fully warmed up, the 2-1 downshift would come very late and wayyy too harsh when coming to a stop. It felt as though you were being rear-ended. This got progressively worse as the vehicle got hotter, until it would actually BANG into gear. Coasting through the downshift and never coming to a complete stop would slightly remedy this, but you could still feel it. Also, severe lurching when taking off from a stop under light throttle, forward or reverse. Again, would only happen when vehicle was warm. Lastly, sporadic short shift in manual or sport mode on 1-2 upshift.

I took it in last week to get checked out, knowing full well the Mechatronic units were problematic, especially on Audi/VW units built between 2007 and 2010. But I didn't mention it to the service rep, as I wanted them to perform their regular diagnostics from scratch without any fore-thought. They couldn't reproduce my problem during their test drives, so I went on one with the tech that was assigned my complaint. After ~20 minutes of stop and go, all of the above problems started presenting themselves, and the tech and service rep told me they would get back to ASAP with what they found. Fast forward about 15 MINUTES, and I get a call form the rep stating they were going to replace the Mechatronic unit and the clutches. I was silently thrilled. They said it would take about three days to receive the unit, and another to swap it.

I'll update as soon as I get the car back. I really hope this is a one time fix, and I can't wait to feel what a properly working DSG feels like (if that even exists lol)
