2003 Audi A6. Consumer seeks reply for request for reimbursement the check engine light illuminated. The consumer took the vehicle to a nearby reputable mechanic who replaced the ignition coil. The consumer is seeking reimbursement, since Audi issued a voluntary campaign stating they would replace for free if needed.

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. 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.

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.
