car stalls out while driving??

is your check engine light on? my guess is the usual common ones:

MAF, idle control valve, throttle adaptation, clogged injector?

No idle control valve on the 1.8t.

I would look at the Maf or maybe even a bad 02 sensor, both will cause the car to stall or cause bye making the ecu think it is running too lean or less air is coming in. Also look for leaks.

fuel filter? air filter? you vag it?

BAD ECU...thats what happened to me...it just died out while i was driving. turns out it was the chip in my car...bad ecu.

[808a41.8t]

im not throwing a cel... i think i'll go have it checked out next week. thanks for the info

is there any RPM that it seems to die out at? does it die at idle or any rpm?

[Quattrocket]

vacuum line mabey? I had one pop off the bottom of my intake mani and caused it to stall.

[Chillmode]

MY VACUUM HOSE CAME OFF AND WOULD STALL... THAT MIGHT JUST BE THE PROBLEM.

Maybe the Camshaft postion sensor, Had one at work last week that kept dieing randomly while driving, but it did throw a CEL

sorry to bring this back up from the dead. school has been killing me so i havent had a time to get it checked but the car seems to be dying out whenever im in a higher rpm. i usually shift around 3k and its been fine. but occasionaly i'll punch the gas in first and thats when it seems to die out. it has also happened in third gear...

maybe you should address some of the earlier suggestions....did they help?

same thing happened to me, cleaned the MAF with carb cleaner and let it dry it naturally. problem solved! may not work as easy for you but i'd give it a try before changing a 180$ O2 sensor and it's a 20 minute DIY.

[TurbousMaximus]

$180 o2 sensor? MY2000's use the wv o2 sensor for about 26 bucks. Just bought one and install took 10 mins it works flawlessly.

[Crisqo]

hmm..
what's the part # for that VW $26 O2 sensor??

are they the same for pre-99.5 O2 sensors?

[$teady$upreme]

bad solder of a chip in ur ecu, or intake hose is off?

[TheGreenAudit]

so I am having similar user 808a41.8t while my Audi A4 2.8 would stall while driving only after I fill in gas? Do any one know what could be the problem.

I second this, but used a electronics cleaner from radio shak that was recommended on passatworld. Additionally, I cleaned my throttle body at the same time so I couldn't tell you what cause my car to stall. Check both and do all the easy stuff you can before sourcing costly help.
