“I own a 1998 Audi A6 quattro (2.8 liter engine). Last winter during a cold spell some part in the pcv valve froze suddenly while driving. This caused the throttle to be stuck at about 4,000 RPM and the car turned into a rocket. Fortunately, I could bring the car to a stop and nobody was hurt. It was quite an experience though, especially since the roads were snowy and icy that day. When I brought the car to the Audi dealer I was told that it may take a week because we are swamped with many other Audi A6, all with the same problem. …”
