Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2003 Audi A4 Owner Comments

A4 4-cyl

  • Automatic transmission

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.

The Audi A4 1.8T that I purchased in Dec 2002 has a sunroof/moonroof assembly. A few times I have noticed that the sunroof opens and closes on its own while the car is in motion.

The sun roof on our Audi spontaneously shattered while we were driving on the highway. It more or less exploded. Glass covered the inside of the car. No one was injured but we almost caused an accident due to the fact this occured during rush hour traffic at 65 mph. Four to five inch diameter pieces of glass fell into our daughters child seat in the back seat. We had had problems with the window opening and closing on it's own and Audi had worked on the window prior to the incident. The window had once again opened on it's own and it was closing when it exploded. It seemed to explode at the end of closing when the window raises upward to seal. Audi claims that the incident could not have happened the way I have stated. I found several other incidents reported on the internet of sunroof explosions on BMW, Volvo, Toyota and Lexus automobiles. Although no one was injured I feel as though we were lucky. If my daughter had been in the car at the time she would have been hit by large pices of glass or an accident could have occured as a result of the glass falling into the drivers eyes. My hair was full of glass. I would like to know how many cases of similar incidents have been reported to your Agency. I tried to look it up on the internet but the search is specific to year, make and model of the car. I would appreciate any information you could provide on sunroof breakage on all other automobiles as well. The window has been replaced but Audi refuses to cover the window under the warranty. I was quite surprised to find that a sunroof is not shatterproof glass.
