Thanks for replying. So I believe that it was the ECM (Electronic Control Module) that was replaced a couple months back that has reduced the severity of the symptoms we're both experiencing. I'm bummed that it still happens because it seems like it should be so simple for them to fix.
I have a 2010, I noticed that yours is a 2011. The only reason I mention this is because I noted in the service records after the ECM was replaced the old ECM had a level of 3 or 4 and the new ECM had a level of 7.
I really don't know what this means but I'm convinced that it has something to do with cars software. I believe this because the symptoms started right after a computer update occurred during the 20K maintenance.
I was lucky enough to run into a VW head tech who now runs is own shop in the area. After describing the symptoms and having him review the service notes he too believes that it is a software issue that VW has not yet solved. He was nice enough to email some of his colleagues in VW at the regional and national level, but unfortunately I have not heard anything back from him.
I keep you posted if I hear anything more.
It's difficult because I can't get the vehicle to display the symptom upon demand so when I try to display the symptom to VW it doesn't necessarily happen.
I guess that VW needs to admit the problem and attempt to fix it three separate times prior to any lemon law action.
In any case, the advice to simply press on the accelerator to resolve the issue hardly carries any merit.

I have a 2010 Jetta Sportswagon TDI with an automatic transmission that is experiencing the same problem and wanted to know if you are also experiencing a hesitation when making a quick stop at stop signs? Would also appreciate any updates on possible fixes.

Thanks northeasttdi for describing this problem, exactly. Your's is not the only manual TDI that has this hiccup problem. Mine is also a 2010 Jetta Sportwagon with manual transmission and does exactly as you describe: it hesitates only for a split second, typically in third gear around 35 mph, but sometimes in 4th, and it always occurs when the engine/transmission is under very light load, such as on a slight downhill grade with no acceleration. It happens both when the engine is hot and when it's cold. This has been happening since we bought the car new in 2010, and it now has 22,000 miles. No dummy-lights have ever come on, period, and I got a similar response from my local dealer...they even suggested I might not be buying the best quality diesel fuel. I was so mad I almost lost it.
I have not really experienced the hesitation at highway speeds (never beyond 50 mph), and I've never had a problem at stop signs or initial take-off. Some of those problems almost sound like automatic transmission issues that I've heard described elsewhere about VW automatic transmissions. Some people may be experiencing two different problems with this car.
In any event, VW has a problem with this engine or transmission. I don't know which it is, but they have to know about it. I intend to take your post back to VW and say "look, I'm not the only one". Please keep pushing on your end and let us know if you achieve satisfaction. Thanks again for getting the issue posted.

I don't experience our issue at stop signs or lights either - I hope that you catch this chris arm. Chris arm, does it happen when you are stopping or when you are starting again?
I'm both relieved to read there's another vehicle of the same vintage demonstrating identical symptoms, but bummed that you too are suffering the issue.
You bring up a a good point that the engine/transmission is under light load when it happens at slower speeds. Recently, I've noticed it in 4th gear too, but mostly in 3rd at about 35. I've tried to isolate the issue to the engine temperature. It seems to happen more when cold, but also happens after having warmed up.
I'll keep you posted to any action taken by VW. I hope to take a ride with the CS manager at my local dealership soon. Let me know your dealerships reaction after you bring in my posting. Maybe we should have our dealerships talk, but then again, if they really are stuck then that wouldn't help us out at all.
#201 of 273 2002 jetta starting/ignition...oil issue
Nov 10, 2011 (9:20 pm)
I have a 2002 jetta 2.0 w/ automatic transmission. What only happened once in a while has now become a daily occurrence. If I leave the car alone for a few hours it's ok to start. But when you try to start the car within a few minutes of turning it off is when the real fun begins. It hesitates and when when it finally does start the rpm revs up to almost 2500-3000 and after about a minute it calms down. I've also noticed that it burns a lot of oil and I'm at the point where I check it every month and have to replenish it each time. I didn't have any leaks until last week when I noticed a few small spots underneath the car on my driveway. I'm not sure if the oil issue has something to with the start up problem. I read somewhere the it may be oil leaking onto the spark plug and the car works "extra" to burn that oil off at the start up. Not certain if that makes any sense........any information would be greatly appreciated:) thanks!

Ditto. I bought an automatic 2012 Jetta Sportwagen TDI at the end of September. I was leasing another car and that lease ended on November 1st. Until November 1st, I didn't drive the Jetta. However, I've now driven it for a little over one week and I've been having the "hiccup" or "lurchu" or, as the service gentleman put it, "like being a passenger in a standard car with a driver who is not an experienced manual transmission driver." I typically experience this when the car is cold and I'm going less than 35 mph. Once the car warms up, I don't experience the hiccup. However, I've noticed the car trying to find the right gear and revving extremely high. This happens when I'm in S on 2nd gear attempting to slow down from 35 to 30 or 30 to 25mph.
The service manager said that it is a "characteristic" of the DSG engine. This is my first VW (I just got out of a lease on an Infiniti G37S Coupe). I've driven the VW for a week. If the symptoms I've experienced this past week are a known "characterstic" of the car, I'll be trading out of it before the year's up and not purchasing another VW product again.

You asked for information... here it is:
I have been "inside" engines several times and I am not sure how oil can "get onto" sparkplug whilst it is not running. (virtually impossible)
It is possible for ANTIFREEZE to leak into combustion-chamber when hot engine is turned off and there is a leak in the head-gasket. The pressure in the cooling-system can push the antifreeze into the combustion-chamber.
This would make engine hard to start after it sits for awhile because the water in the combustion-chamber makes the engine "work harder" to keep itself running.
To check for this type of problem, check the exhaust-pipe when you initially start the engine, it will be blowing white smoke (steam) for a minute or so until the water is blown from the system.
As for your oil-consumption issue, the VW 2.0L engines are KNOWN to consume some oil (for 2000 - 2002 model-years) This is not damaging in any way as long as you keep some oil in the trunk so you can top it up when you get gasoline. That is FAR cheaper than paying to get it fixed.
Also, it would be wise to clean your snowscreen annually. On the MKIV VWs, it gets pretty plugged up after 12 months of driving.
You may also wish to clean your MAF (Mas AirFlow) sensor.

Did you ever get this problem fixed??
My 2001 VW Jetta is doing the same exact thing. It will run fine for a week or a could days then all the lights will flash on dash and the car will eventually lose all power and shut off. I had my car towed to my dad's house and he looked at it first assuming it was the alternator but he had my car running and then unplugged the battery and car stayed running. He re-routed some of the wires in the little black box on top of my battery, but we still haven't figured anything out.

Thank you very much. After reading this I'm starting to get the feeling it has something to do with the Mas Airflow sensor. Going to try to clean that and the snowscreen this weekend.
