2003 audi a6 had problems with the engine light, smoking, and little to no acceleration. Consumer states that after a few repairs the problem is not solved and wants to be refunded her money. *nj the dealer informed the consumer the #1 and #3 coil needed to be replaced. The consumer drove less than a mile and the check engine light came back on blinking and the vehicle was moving very hard. When the consumer returned to the dealer, they diagnosed the vehicle again, the consumer was told the #6 ignition coil needed to be replaced. Because no one ever test drove the vehicle when it was suppose to be fixed the first time, the dealer replaced the #6 coil for free. The consumer left the dealership again only to have the engine light come again, but it wasn't blinking. The dealer diagnosed the failure and stated it was the torque converter clutch circuit performance.

The LED portion of the instrument cluster fades out on hot days making the gear selection indicator (prnd321) shown in the display unreadable. This is a safety issue because the driver needs to know what gear that transmission is in at all times and a fading display leads the driver to guess rather than know. This fading started three years ago and has gotten progressively worse with time. It only happens on hot days when the car is parked or driven in the sun. We have lots of sunny days in california!
I was driving my 2003 audi a6 3.0 quattro on thursday 04/03/2008 around 10:30pm. I was traveling 25mph on sylvan avenue in englewood cliffs, nj the check engine light illuminated on my dash board and started flashing, I immediately pulled over to the side of the road to diagnose the problem, when I pulled over I saw smoke coming out from under the hood of my car. I immediately turned of the vehicle and popped the hood to see what was going on... I popped the hood to find the ignition coil on the third cylinder (back left cylinder) had started on fire with about 12inches of flames. Thank god this all happened I about 30 seconds and I was able to get the fire out, otherwise the whole car would have burned to the ground. If I was stuck in traffic or on the highway this car would have most definitely burned to the ground. I feel very lucky my two year old daughter was not in the car with me. Nevertheless, the ignition coil is completely melted as well as the wiring harness. I always have done all the manufacturer recommendations on the vehicle and the car was just at the dealer service center on 04/01/2008 for maintenance, I had them look over the whole car and they said everything was fine. After speaking to service technicians at audi I have found this to be a commonly recurring problem with their ignition coils, specifically pertaining to the third cylinder, they claim it overheats because the design is to close to the catalytic converter. All I know is something should be done, I have pictures of the damage where you can clearly see some type of electrical malfunction that I would be more then willing to share. Please someone do something before a life is lost from this manufacturer error.!!!
Faulty ignition coils (so far 3 out of 6 cylinders went bad). On three occasions after starting and putting the car into the gear, shaking ensued and the "check engine" light turned on. The car had to be towed each time to the dealer where the faulty parts were replaced.
