Strange Steering Problem
 

I've had my 2005 A6 3.2 Quarto for 6-months. Due to bad weather I didn't get a chance to drive it too much on freeway as most of my commute in on streets. Lately I am noticing a sporadic strange steering pull when on freeway at 60 MPH on dry pavement. It feels like the car wants to change lane by itself all of a sudden! I checked the tire pressure and lugs and all seems to be fine. Has anyone else experienced anything like this? I don't even know where to start. My Audi dealer is completely useless and unless it happens in front of them or some problem light is on, they will not do anything or even any investigation.

have you had it aligned lately, that's were I would take it.
