Hello,

Been having non stop problems with my 2006 A3. Only happens when I've been driving for about an hour or so with the AC on. When i come to a stop and then take off again, my car "stalls" or looses power like its shutting off and then suddenly kicks in and runs fine until I stop and go again. This only happens after I have been driving around for a few with the AC on. The check engine light comes on temporarily and then shuts off. I keep taking it in but because there is no check engine light on they are unable to get a hard code. I'm loosing it here!

 

Hey,

I never the issue with my Audi, but had the same issue with a Dodge car i once owned and seems like camshaft sensor. Have the car scanned for the error codes.

Drewlocks,

 

Mine did the same. It was actually the sensor on the HPFP. I thought it would be the pump itself or the cam follower but it was just the sensor that was bad. Very simple repair and cheap as well.
