CC turn off while driving.

[chicositos]

Hi,
I have a problem with my CC 2011 with 18,000 miles. (2.0 T DSG)
It happens 3 times, while I´m driving like at 18 mph, it turns off sporadically.
I already scan the car, and non error registered. Has anyone has the same problem??
What could it be?
I still have warranty, but I want first a diagnostic before I left the car at the dealer, because sincerely I don´t trust them at all.
Thank you for your help.

Did you use a quality scan tool like VCDS (Ross-Tech) vs. a generic OBDII scanner?
This'll be a tough one for the dealer to diagnose if nothing is flagged in the control modules and they have nothing to go on

Yes I did use VCDS 10.8

I had something like this happen when I didn't get the hose clamp back on correctly after installing a CAI. The clamp behind the MAF was loose and the MAF was basically throwing its hands in the air. Car would go dead when I came off the gas.

Thank you, but I don´t think is that, your check engine was lighting?
It feels, like when you release the clutch.
I feel it maybe be 3 things:
Alternator
Crankshaft sensor
DSG mechatronics
I hope is not the mechatronics, because it shifts perfectly, and I don´t have any error at the scan.
HELPP!!!

There is a recall on the ignition module. Have the dealer check your VIN to see if it qualifies.

No check engine light in my situation. But it's an easy thing to check to make sure there's nothing interfering with the MAF. So I figured I'd mention it.

i had the same thing happen to my CC. I have a 2011 2.0 DSG. It happens to me when im in heavy stop and go traffic. As im slowing down to a stop the engine stalls and the parking brake engages. i have to shift to P, restart the engine and release the parking brake. All in the middle of traffic.

I took it to the dealer and they said they reflashed the tranny. Drove it out of the dealer and it happened again.

I took it back to the dealer but they couldnt replicate the problem so they didnt know what to fix. but they happened to find something wrong with the fuel pump so they replaced that.

i havent driven in stop and go traffic since then so i dont know if its fixed. it only occurs in heavy traffic with the a/c on.

hope this helps

by the way the dealer said there were no hard codes and i never got a CEL.

I would say it is the alternator, or a huge vacuum leak. How does it die? Does it just cut out, or does it putter into a stall?

[dasautocc]

motor stalls completly like a manual transmission car when you dont push the clutch to stop.

[Abide]

I have had some horrendous vacuum leaks that have caused this to happen - boost gauge will show this, but this is doubtful. I am not familiar much with the DSG, but mine has already done some strange things.

I would test this by driving in tiptronic mode, or whatever the VW term, if that is incorrect.

Edit:
I have read that the mechatronic unit can cause false neutrals and jerking shifting. I am up against the dealer on the jerking and lurching. Hoping to get that replaced.

Thanks for your replys,
I think is not going to be easy to find the problem, at least is happens like once in a week, but on friday I have my appointment at the dealer to check out what it is, I hope they can fix it.
I let you know the advance.

happened again yesterday in traffic i guess its back to the dealer for the third time...

[chicositos]

Well, here are the updates.
I took my car to the dealer, and guess what, they didn´t find anything!!
In the last days, I made the basic setting to the DSG, and after that it seems to works perfectly.
Any advance I let you know.
