Since there is no ignition-system on a diesel engine, there is only 2 ways it can 'stall'
1) No air
2) No fuel
To lose air, since there is no throttlebody, the only way that can happen is if the overrun-protector somehow closes.
To lose fuel, there are several ways this can happen and is most likely the reason a diesel engine stalls out.
Using logic, I have pretty much narrowed down the problem.
The CTS on the 2.0L engine is VERY easy to change. First, you should open the hood and look at it. The new-improved one is GREEEN. If yours is not green, then replace it.
It is trivial to replace, I changed the CTS on my daughters 2001 2.0L in the dark while she held a flashlight. It took about 10 minutes.
The CTS is under $20 including O-ring and spare clip (incase you break the existing one)
Of course, troubleshooting a problem online has inherent inaccuracies. Your problem may be something else.
At this point, I'm wondering if I should just have the dealer buy the car back. I LOVE it otherwise and am so disappointed I'm having these issues but am worried about it leaving me sitting. Is this going to be one of those situations that I'm constantly having to get the car looked at, worked on, etc.? Suggestions, feedback, advice? Thanks so much!!!
It would not hurt to try another treatment to see if you get any more improvement.
Also, did you clean the snowscreen? (I clean mine annually and it is pretty plugged each time)
My uncle has driven the car on road trips from Connecticut to Boston without any problems and has never faced this issue, it only happens to me. Could I be slamming on the brakes too abruptly or confusing the car?
MAF or ECT may be suspect.
MAF = Mass AirFlow sensor
ECT = Engine Coolant Temperature sensor.
I agree with the mechanic... It is very likely that the TB is off by a tooth which can really mess up the engine. (bent valves...etc) You may get lucky and after re-timing the TB, your engine will be OK.
I am concerned that you suggest that the pullies and TB are not even moving when you crank the engine... this is IMPOSSIBLE!! (The crankshaft pulley *is* the engine)
As for the 'overheating' issue - did you perform a bleeddown test? This would tell you the condition of the head-gaskets. Leaking head-gasket can cause overheating.
When you initially turn the key to ON (before cranking engine) you should hear the fuel-pump run for a few seconds.. .it is mounted INSIDE the gastank and sounds sorta like a 'rumble' near the rear of the vehicle.
You drive the vehicle for a week or so and get the problem to occor. (you can push a button on the gizmo to "mark" when the problem happened.)
The dealership simply uploads the data from the "recodrer" to the factory reps and they can diagnose EXACTLY what happened....and propose a proper repair action for the dealership to take.
I have done similar things using my laptop computer connected to the port under the dash of several VWs.... Anyone can do it with any laptop and this software
I'm really disappointed that the recall only dampened the coinciding frequency problem, rather than eliminating it, and that VW didn't address it sooner. However, I'm very happy to have it essentially resolved.
My daughter has the same car, same problem!
Really scary when it happens during a shift and car stalls in an intersection!
Dealer totally unhelpful - "We cannot put any more time into this.' "We cannot throw parts at a car (because VW will not reimburse us for the repair)." "The car is operating according to specifications."
Dealer had car for 3 weeks, did not get the problem to repeat because they did not do what I told them would get the problem to repeat.
I am totally frustrated and ticked off at being stonewalled by VW.

Does anyone have a clue to what is going on with my car? Please HELP!!!
I told the dealer you no about the problem and if something bad happens I will own your dealership and walked with the whole waiting room sitting there with mouths wide open.
ANYONE ELSE OUT THERE WITH THIS TO
For a much longer period, the car will shake like it is going to stall when I come to a stop. It never has, but it feels like it is choking for air or fuel. I drove a 1995 E300D Benz from new until 2010 and put 300K+ miles on it and it never stalled, so this is frustrating. Scared to put my daughter in the car now. My local dealer won't return my calls either. Frustrating.
I called the service dept right away (the car is still under warranty) and was told just to restart the car. They said not to bring it in for service unless it happens again. But there was no reason whatsoever for the car to stall. I was just fortunate that I was in a parking lot when it happened. Is there a way to report this problem to Volkswagen corporate, rather than the local service department? I checked the NHTSA website, but couldn't find anything there. But we should find a way of submitting these problems in the aggregate to both VW and the NHTSA.
So are you still having issues?
I was so ticked off, I traded in the car on a 2012. I told the finance manager right then and there, if this 2012 TDI does it too, it is all over! VW is going to have to step up - this is their problem, not my problem. Well, trade in was a bad move, should have turned it in as a LEMON and gotten a new car pretty much for free. Because, guess what?? The 2012 does it too!! I could scream. As of my 5000 mile checkup, I have put the finance manager on notice and have given them 3 weeks to get back to me as to what VW is going to do about it. Time is up. I am on this later today.
Good luck, VW is stonewalling, just like Toyota did with those surging problems.
What was the ultimate cause of your problem in your post of 7/11/11? I bought a used 2007 Jetta for my daughter last summer and she had some problems with it - had a lot of warranty/recall work performed, including replacement of the coils (I think). Recently, my other daughter drove it to the door of her apartment at college and it died and I can't get it to start at all. The gas gauge said past empty so I added gas just to make sure she hadn't run it to empty. The battery only clicked, as it does when the battery is about dead. I jumped it and the starter cranked energetically but endlessly without the engine ever kicking over - even a single surge. It's as if it has either no fuel or no air, or some other mixture problem. What did you learn from your bad experience from 2011?
When I turned it back on, not only did the glow plug light come back on but so did the "check engine" light. We had it towed to the dealership where they looked at it and told me there had been a "failure in the fuel pump which caused." (& I'm quoting here) "shards of metal to spray throughout my engine." Sounds great, right?
I bought this car brand new in 2010 with only 30 miles on it. I had noticed a bit of a hiccup every once in a while which reminded me of how it felt when my old car would have bad gas or something in it - like it just wasn't getting the right fuel for a second and then it would go again. Aside from that hesitation, we never stalled, never had trouble starting in the morning, never had any signs that anything was wrong and then one day...BOOM! You have shards of metal in your engine.
I'm glad we purchased the extended warranty but after waiting over a week (I'm trying to be patient because it's the week before and now Christmas) to hear from them to see if my issue is "covered" I started reading reviews of the company and it's made me nauseated. I came on here to see if anyone had any sort of similar problem to mine and your thread was the closest I could find when it came to mentioning the fuel pump.
I'll keep you updated as I learn more. :confuse:
8 months into this lease this morning my car hesitated to start then idled so low that I tought the car was going to stall. The stalling sound was making the car move like it was bucking but never stalling out. Check engine light came on. Was bucking down the road luckily to make it to work that is only a mile away.
Called the dealer, it's going there tonight and I told them I don't want it back until it's fixed. I will be calling VW customer care tonight to list these problems. I'm so frustraited, a 3 year lease is too long for this piece of crap. They don't make VW like they used to. JUNK! :mad:
Thanks!
