What owners wrote
Ignition coil failed on highway. Car "shook" violently until stopped in parking lot. Once car was off the road, the coil housing caught fire. The fire ultimately burned itself out, and the car was towed to the local dealership for repair. The dealership notified audi USA of the defect and recommended vehicle replacement. Audi USA elected to repair car under warranty. Multiple failures have occurred since (see list). Ts
I am one of the many audi owners that have experienced a problem relating to the ignition coils of my 2002 a4 quattro. Like other drivers, I was operating my vehicle on an interstate highway when my engine began to loose power, while simultaneously the entire care began vibrating vigorously. After one flatbed trip to the local dealer, and I was informed of a malfunction of one of the four ignition coils on my car with a total of 12,000 miles of use.
