I have a 2001 VW Jetta Wolfsburg, second-hand. I now have 134,000 miles on it and need to take it in for service and probably to replace the timing belt. The previous owner gave me partial service records and incomplete receipts.

I had the infamous check engine light come on for catalytic trouble. Horrible VW dealer said I needed to replace the whole catalytic converter for $500 + labor. I didn't have the money so I had a friend clear the code before my emissions test. Luckily, it passed, no problem. So my mechanic friend figured it wasn't the cat and changed one of the O2 sensors. He says they are maintenance items anyway. Much cheaper at $70. It got rid of the check engine light... and I'll never trust the dealer again.

Now onto the new check engine light. Misfiring of cylinders. I changed all the ignition coils out a year ago to the new ones (I think they were round "T") and also the spark plugs. Any ideas?

FYI- generic autozone sparkplugs for this model are not calibrated correctly. Buy from the dealer!

"FYI- generic autozone sparkplugs for this model are not calibrated correctly. Buy from the dealer!"

2nd to that, I did the same thing, caused me to do exactly what you did.

What are the symptoms around the misfiring? Just the code is never enough to troubleshoot these cars. Could me an air leak, MAF or other fuel/air mixture related issues.

My 01 Jetta is 92 miles is having the same problems, so here is the list of things I have changed:

Speed sensor

Turbo sensor

Coil packs

Battery 2 times


Spark plugs

The car runs fine, but when I get to a stop or hard turn, the car stalls and the battery light comes on, and when I restart the car APC light and misfires until stall.

Also I found out if I remove the ECU and put it back, the car will run OK until stalling again.

So my last try will be the ECU; dealer wants 580 for it. Does anyone know if this will fix the problem??

Please help, I had to put a lot of money into it and times are hard.

Just had mine in about 2 weeks ago, had done all the things you mentioned and was fed up. Anyway, looks like the throttle body was my issue. Dealer said it was 6-700 to replace it, but wanted to clean it out first see if that solved my issue. Well the stalling stopped and the check engine light went off, it recently came back on but the stalling at least has not come back so the light may be for something else. My suggestion, try having them clean out the throttle body, relatively cheap before doing anything else.

I too am having issues with my 2001 Jetta 1.8. I bought the darn thing 1.5 yrs ago from a dealer and since then have spent over $3000 in repairs. Just recently I replaced the timing belt and water pump, and just last week replaced the back exhaust including the catalytic converter and both sensors. So here we are this week and yesterday my car stalled when coming to a stop at an intersection. It wouldn't start right away, kept turning over and over, I had it pushed to the side of the road and after a couple of minutes it started back up. Drove it back home and it stalled again at another intersection, and wouldn't start for another 5 minutes or so... any ideas?

I have a VW Wolfsburg myself. For the stalling when starting the car: you should let the RPM go under 1000, let the oil flow into the engine; even more important after a very cold night. It takes a minute or two and will solve that problem, and is better for the car (not just VW, you should do it with any car). The rest of the problems you had are linked to the dealership giving a poor service, and is unfortunate since I had similar issues.

I agree the car is expensive to maintain, but the quality of the ride is worth it and most of the problems happen only once, fix it correctly (I do it myself) and you're fine.

I have a 2001 1.8T Wolfsburg edition, bought used. Remind me never to go near a VW again.

I have the same stalling issues as the rest of you. Engines stalls at every stop. I can get it to start again either by engaging the clutch or by using the starter, but this is not a permanent solution. The engine diagnostic indicates that Bank 1 O2 sensor is bad, but I have no idea why that would lead to such consistent stalling. I may disconnect the sensor to see if that improves the situation.

Did I mention, I WILL NOT buy a VW again.

I got a used VW Jetta 01 1.8T Wolfsburg recently, and have also had many issues ranging from annoying to severe. Needed new sparkplugs, new timing belt. Recurring system rich bank 1 check engine, got 02 sensors replaced, air flow sensor cleaned, leaky valve fixed, light still comes on. Have decided to ignore system rich, and accept perpetual check engine light.

The car often had trouble starting (revs jumped between 500 and 1000 repeatedly, then stalled), then drove poorly, when cold. Read up online and discovered needed new Engine Coolant Temperature sensor. At least fixed that problem. Then started the car one day and it shook violently, had very low power, and check engine light flashed when touched gas. Needed new engine coils.

Fun to drive, but very unreliable car that requires frequent maintenance. To add to all that, plus the annoyance of always seeing check engine light, the driver door has a slight leak, the driver door doesn't register when I open it so the alarm re-arms, thinking I haven't opened any doors, the AM reception is lousy, and the center armrest falls onto the handbrake.

My 2007 Wolfsburg Jetta just stalled on me last night. The ESC lights came on, then the battery light came on, and then the engine died. I lost all power and coasted off to the side of the road. I thought it was the battery, but all my lights, radio, headlights worked. I tried to start it, but the red steering light came on too. I got it towed to the dealership because it should still be under warranty (<4 years, <40,000 miles).

Has anyone had this problem? Did they figure out the issue? Recently the NHTSA is looking into 2009 VW Jetta TDI stalling issues - would this apply to non-TDI's too?

Any info and advice is appreciated.

I have a 2001 VW jetta Wolfsburg Edition 1.8t.

I was having the stalling and hard idle issues as well. I did see one post about removing the throttle body and cleaning it with alcohol. I did just that, and I cleaned all the carbon from the inside with a Brillo pad.

I did change one O2 sensor. The one closest to catalytic converter, but that was month ago. I opened the sealed part of the throttle body as well, and wiped the inside with alcohol. I also carefully bent the fine metal brushes up a little more to secure a firm contact on the PCB.

My car has not stalled or idle rough since the cleaning. In fact it's now hard to tell whether or not my car is even on. My acceleration has returned as well. I can gun it at the green light without jerking to a stall.

Thanks for the throttle body tip. I forgot who posted it, but I love you man.

This car is a blessing because it's forcing me to learn to DIY. Now to fix my speedometer and failing fuel level sensor. If you have any tips for that, please post them. Thanks.

Did they ever figure it out?
