On three separate occasions my 2003 A4 (1.8T) started shaking violently as I accelerated from a complete stop. Every time it happened the check engine light came on, the car lost most all of its power and was difficult to steer, and wouldn't get above 15 mph. And every time it happened I was stranded in the middle of traffic, having to coax the car over to the side of the road and out of harm's way. The car was towed each time to the dealership where I was told that an ignition coil (or two) had blown. All 4 coil packs had to be replaced within a year at a cost of over $900. Audi knows they produced cars with faulty ignition coils in A4 cars equipped with 1.8 liter engines in the 2001, 2002, and early production 2003 model years. In February 2003 they announced that they would replace these coils free of charge to the vehicle owners. Although my car is an early production 2003 model, Audi usa told me that my car was produced very soon after the range of cars covered in the replacement. Meaning that I was responsible for the cost of all repairs. I do not believe Audi is certain their replacement action covered all defective coils, especially as my car was produced in the same time frame as those that were part of the replacement. Faulty ignition coils exist in a far greater number of cars than what Audi recognizes and covers in their 2003 replacement action.

Audi A4 6-cyl 3.0L avant 2003 model year. Coil pack #2 failed on Sep 28th 2007. Audi has had a recall for the 2003 A4 4-cyl 1.8L engines but not for the 3.0L engines. The vehicle only has 37K miles on the odometer. It's likely that there will be more cp failures, until I have all of them replaced. There should have been a recall for the 3.0L engine as well.

I purchased this car on 1/24/07 with 22,422 miles on it. Six days later the engine light was flashing, it was shaking unbelievable, would not run properly, go over 20 mph. I returned it to the dealership I purchased it from, they replaced a coil pack. Within a short time, on February 14, 2007, the engine light had come back on. At that point I brought it to the nearest Audi dealer. It needed a turbo bypass valve replaced. Friday, March 9, 2007 the engine light had come on again. I brought it to the Audi dealer once again. They reset the engine codes and say it has had a random misfire. Today, March 11, 2007 the engine light is flashing again, and will not drive over 20 mph. I am having it towed to the dealer in the morning, today is Sunday and they are not open for business. I drive about 1,000 miles a week and I need my car operational. I worry each time I drive this car, I have to return it to the dealer almost weekly. It has low miles. Carfax states this automobile has a clean history and is under factory warranty until 6/07. The booklet obtained with the purchase of this car states the 4 yr/50,000 mi warranty became effective 6/03 which would leave the remainder of the fully transferable factory warranty valid until 6/07. The Audi dealership will not honor the warranty, saying that it expired 1/31/07. The car now has 29, xxx miles on it and I have had nothing but trouble with it. The sunroof motor also needs to be replaced, as I am told by the dealer, who then told me the motor is $501.

On November 14th my A4 1.8 stalled, was towed to the dealer, a coil was replaced...when I drove the car home it would thump and jerk up around 60 mph. I returned it to the dealer who stated that it could again be another coil but were not permitted to replace all the coils the day before because manufacturer wouldn't pay for anything more than the faulty coil...even though they figured more might fail...well, it turns out it was the "throttle" - they reset it and I picked up the car and started driving home when it thumped and jerked again...turned around and returned it to the dealer...this all happened on the 15th...it is now the 18th and after working with their engineers, they fear they may now need to replace the entire transmission...I am just glad that I have a loaner car and that I have 5K more miles on my warranty...I think I am going to by the extended since this is 3 huge problems in 5 weeks time!

On October 11th my fuel filter and pump were replaced and a road test was completed...on November 14th (5 weeks later) my A4 began to shake and the mil came on. I pulled vehicle to side of the road and had it towed to dealer. Dealer informed me that ingnition coil failed and had started to affect the spark plugs and was only running on 3 cylinders as a result. They replaced the coil and completed a road test - however they had completed a road test 5 weeks ago too - so I am feeling lest confident when I drive...fearful of driving in less familiar locations or in any lane except the slow lane in case I need to pull over.

The contact states while driving at 10-15 mph the engine began to stall, followed by the check engine light. There had been no prior incidents. The vehicle would not accelerate beyond 20 mph. There was the distinct odor of something burning coming from the engine compartment but no smoke. He pulled over to inspect the vehicle. He could not determine the problem and the vehicle towed to a dealer. The dealer said there was a faulty ignition coil in cylinder three. This was replaced under warranty. The same symptoms later returned at a speed of 55 mph. There was a significant loss of power and he immediately pulled over. The vehicle was towed back to the dealership. The dealer replaced the ignition coil in cylinder one. He offered no explanation of this ongoing problem. Updated 01/19/06.

My 2003 Audi A4 failed to start on December 24th, 2002 and May 2nd, 2003. Both times I was left stranded. The first time they replaced the steering lock, ignition cylinder, and steering column. After the problem occured a second time, they replaced the instrument cluster. This problem occurred at 5,000 and 11,000 miles and should not happen to a new car. It is a safety issue because it has left me stranded 2 times.
