I was driving on interstate 85 in south carolina returning to charlotte, n. C. When the engine of my 2004 Audi A4 started skipping severely. After pulling to the side of the road and letting the car sit for a while, I restarted the engine and the problem seemed to minimize somewhat. The following morning on the way to work the engine started skipping severely, and the vehicle seemed to be bucking heavily. I was able to get out of the traffic and pull to the side of the road. I called Audi of charlotte, and they advised to drive the car to there facility if it was drivable. I managed to get the car there driving at 25 mph with the motor skipping heavily. The problem was diagnosed as an ignition coil failure, and was repaired at a cost of $472. 04. This was the second major failure of a component of this vehicle in a time span of two months ( fuel pump-6/14/07 ), and as a female driver I am concerned that I'm going to be left on the side of the road at night.
