So yesterday i was driving back from the dealer after getting new headlights put in...well first off the light they put in is facing up not to the ground FML
then i m driving on the highway doing like 85mph n next thing i know the car shuts off...FML
i slow down pull over to the side and start it back up and sit it n wait for a couple mins ...as before i had stated in a thread i started that my rpm would go up on its own when my car was sitting still and this occurred again as i waited.
Drove the car this morning ran pretty well.
Any suggestions on what it might be>?

Not sure... it's pretty strange why it would stall you are still driving.

Definitely bring it up to your dealer because it's a safety concern. I'm not sure if it has to do with valve spring recall that has been popping up on here.

Do you also hear noises when cold starting your engine?

send it back to the dealership, i'm wondering even though it didn't throw out CEL codes maybe they can check the ecu memory?

yea i hear alot of cranking when i cold start it n i dont go over 3k rpm when i start driving and i let it sit for 5min before i drive it usually

Maybe they forgot to plug something back in?

To me it sounds like some of the symptoms seen in the thread on carbon buildup.

How many miles on your car? Did it completely stall or go into limp mode?

Imnutz4jdm

the car has 56k on it n it fully stalled out ...pretty much it shut off

Sorry to hear about this!

My IS250 RWD has acted like its going to stall out or die (when going slow in like a parking lot) but never actually has. Happened maybe twice... wondering if i should take it to the dealer before i get caught on the highway like the OP. My car only has 23-24,000 miles on it though.

Correct me if I'm wrong, but I heard RS4's are notorious for carbon buildup issues.

ok thank you for the warning there we go thats out of question
haha

Could they possibly have disconnected the MAF sensor to reach the bulb for replacement?

a disconnected maf sensor will cause the car to start up and die instantly throwing cel codes immediately. It will start the second time around though.

I dont think thats the case here.

sounds like carbon build up. happend to my car before i bought it. i called the dealer to check if it had any problems when i was buying it and they said the exact same thing that u were describing but that it wasnt a big deal and they fixed it.
