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.

Electronic deficiency overriding speedometer and odometer on the car. When car is first started...three loud beeps occur and the ABS and brake warning lights start blinking on and off. Following the three loud beeps both the speedometer and odometer are disabled. When driving, the speedometer does not indicate the speed of the vehicle and the odometer does not indicate any mileage driven.

I was driving my 2004 Audi A4 (1.8, convertible) on a local road at approx 30mph, when the accelerator suddenly dropped from under my foot and the car accelerated very rapidly. It felt like the cruise control had come on by itself (the cruise control was completely off at the time). I put the car in neutral and pulled over. When I shut the car off, the gas pedal popped up and felt normal. When I turned the car back on several times, it continued to immediately accelerate all the way with the gas pedal dropping to the floor. The car is now being towed to a mechanic. Had I been in a tighter situation at the time, it could've been ugly.

The vehicle according to the Audi dealer has a bad automatic tcm transmission control module that causes the car to slip gears or not shift down when coming slowing down and then needing to accelerate. The vehicle will stay locked in 3rd gear and when pulling out on to the freeway or a busy street it makes it difficult to get up to speed. When parked on a slanted driveway or street the vehicle may not engage a gear once it has been selected and the car will roll down hill.

2004 Audi A4 1.8T engine sludge--complete engine failure. Audi absurdly refuses to honor their own extended warranty on the basis the car was run without oil. The engine failed internally because there was and is sludge blocking lubrication ports to the moving parts, I.e., failure. This is my executive synopsis, but I have volumes of supporting evidence, unbelievable as it is to think this could happen in America.

I own a 2004 Audi A4 and last year my passengers side headlight started to flicker and would even go out as I was driving! major safety hazard! I am on many Audi forums and there are pages and pages of the same issue! do you know how dangerous this is for me and my children! and last time I went to Audi to fix my right (drivers side) headlight it cost me over $1,000 dollars. I just do not have the money for that right now and I think it is ridiculous that Audi customers all have the same problems and the NHTSA or Audi are doing nothing to solve it. I keep this car up in immaculate condition with folder and folders of service pages so its not from neglect and everyone else is having the same problem! I don't know if you know how dangerous it is because the only way to turn my passenger side headlight back on when it goes out is to pull over shut my lights and turn them back on then it comes back on and will either stay on for a little bit and then start flickering again and go out again. I am taking my life in my hands driving this car and its my only car to commute with. This issue needs to be fixed very soon!

While driving the car, there was a pop, then the car started running poorly. I stopped the car and checked the gauges; the check engine light was on. I returned home and called the dealer who suggested I call for a tow truck and have it brought in. He said that the vehicle couldn't be driven in this condition. He told me it was probably the coil pack. I called a tow truck and it was taken to the dealer. They replaced the coil pack that had been recalled at no charge to me, it has run fine since.

2004 Audi A4 has had several repair problems. Consumer feels that the vehicle could be in an accident due to the problems. The consumer stated all of a sudden, the vehicle stopped running while in traffic. The dealer was unable to find any problems. Several months later, the engine wouldn't turn over. The battery was replaced as well as a bulb. The convertible top would not go down. An electrical part on the convertible was replaced, one of the headlights had burned out and the crank pulley was replaced.. the convertible top became stuck in the open position and had to be replaced. The convertible top replacement caused damaged to the headliner as well the drivers side window had a leak. Updated 02/07/11

I owe a 2004 Audi A4 convertible. In late February of 06, I started to experience problems when I put the gear on D (drive) or R (reverse) and gave gas; the car did not move at all. Dash board instrument was not responsive either. Initially I thought this was due to cold weather. On March 13, 06, I was running errands in a very busy area of northern Virginia. The car was warm as it has been running for a couple of hours. I approached a busy intersection to make a left turn. When the road was cleared, I attempted to move forward but the car was totally frozen - it would not move regardless of how much I pushed the gas pedal. I was now facing the oncoming traffic of three cars blowing their horns like crazy. I just could not move the car and was terrified that I would be hit by the oncoming traffic. The oncoming traffic came to an abrupt stop and after several attempts I was able to move the car. I was very scared and called the Audi of tysons corner (hbl) in vienna, Virginia immediately and took the car in that day. The next day (3/14) afternoon, I received a call from the service advisor indicating that they were not able to duplicate the problem and that nothing was wrong with my car. I insisted that they recheck as I experienced the problem several times and that the last incident was could have been fatal as I was stuck in the middle of the intersection. They agreed and kept the car for another day; however, the next day they called and said the same thing - nothing wrong with the car. I picked the car on March 16, 06. While waiting in the lobby, I saw another Audi A4 convertible driver. I approached her about my experience and asked if she experienced the same or similar problems. She said yes and that is why she brought her car in along with a regular service check. She received the same feedback from the Audi of tysons - nothing wrong with her car either. I have the name, phone number, etc., of the other driver if needed.

Vehicle heated up under the steering column, especially when driving 50 mph or greater. Consumer took vehicle to the dealer, and they test drove the vehicle for eight days and found the same flaw as the consumer. Manufacturer indicated that the vehicle was operating under normal range, and there was nothing they could do.
