Hi, I have had this car since March 1, a little over 5.5K mi. Every once in a while, about 6 times total, I have been driving between 40-55 mph and the car stalls/hesitates. It is a very noticeable hesitation that is very short lived. I don't think it is just a fuel delivery problem since I have completely taken my foot off the pedal and then back on and it has a completely different reaction. Not as violent and it takes much longer. This car has the 6-speed manual and I usually keep it between 1400 and 1800 rpm.

Once my "03 Ford diesel pickup did this and it turned out to be a cam position sensor. Any chance this is the same problem?

BTW, other than this, the car is running really well. I did a run down to Logan, UT and back last week and averaged over 46 MPG

I have the same car and mine has never done that.

I have the 2011 Sportwagen TDI, 6 speed manual, and it does the same thing.

Not sure, but it wouldn't be the regen cycle running would it? I'm not sure if regen is noticeable or not while driving...

So how's Logan, UT doing? I lived there a few years ago. I miss the Mountains.

Logan was nice. Still tons of snow on the mountains. I cannot tell if a regen is going since there are no indicator lights. I don't think a regen itself could cause this abrupt of a transition in power delivery.

I 've had the same thing happen a couple times to be exact...2011 Jetta with 7950 mile. DSG.
My Ford Expediton had the same issue and turned out it was the fuel pump going bad. Let's cross our fingers and hope this isn't the same thing. I know...not comparing the Ford to the VW but same symptoms sometimes lead to similar issues.

These cars don't like to be driven with too light a foot all the time.

The vanes in the turbo need to be exercised every now and then.

Try a few blasts to 4500 rpm and see if your symptoms diminish. If so, great. If not, you need a diagnostic scan. This is not normal.

I have only experienced this twice on a cold start, but this hesitation has been experienced by MANY people to varying degrees and has been talked about ad nauseum. If you search for it here you will find hundreds if not thousands of posts on this. There doesn't seem to be immediately anything wrong with the car, it just seems to be some type of glitch in the software or in a sensor somewhere and beyond being somewhat startling doesn't seem to have much of an effect on driveability of the car.

PaulGiz, a diagnostic scan on a car that does this will yield nothing, unfortunately. Your advice about the keeping the VNT clear is important though, but it seems the hesitation that many experience seems to be unrelated to VNT issues (this is not my opinion, this is the general feel from what people have done though previous posts to try to figure out what causes this)

Fuel Pressure Regulator Failure

First time posting. Lots of great help in here...thanks!

My 2011 JSW (DSG transmission) with 28k miles stalled seconds after a DPF regen cycle while going under 5 mph in a parking lot.

Took it to the dealer and was told the fuel pressure regulator failed (and was replaced) but had nothing to do with the DPF regen cycle. They held my car for two days to get help from corporate to resolve the issue...I felt like I wasn't getting the entire story.

So far so good but not sure if this is just the beginning of future fuel-related issues. I otherwise love my car!

A stall and a hesitation are two completely different things. This has been an issue on many of the cars, however mine has not had this problem pronounced. Every now and again I feel a little something but I'd never say it is noticeable. It seems that the car can sense when you are changing from uphill to downhill combined with accelerating/decelerating and thats when it does it. I am confident this isnt a problem, just a quirk. Its definitely a little strange, but something to get used to and not worry about.
