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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2006 Audi A6 Owner Comments

problem #1

Sep 212006

A6 6-cyl

  • Automatic transmission
  • 7,050 miles


I have a 2006 Audi A6 with VIN number waudh74F96nxxxxxx. On September 21st when I was driving the vehicle in my office parking lot, the transmission dropped dead when vehicle was in motion and I was unable to move the car. I stopped the ignition and restarted the car and it came back. I had the same issue on September 26th, after pulling off my driveway and after I was exiting my home the car died again luckily I was on local road and this time after starting the car, I started getting check engine light. I contacted Audi dealer and was able to get appointment on October 3rd. The dealer informed me that my car had engine oil sludge issue and they had to clean the engine and it would take at least a week before they could give me the car back. After a week dealer informed me that the vehicle was serviced but would not go above 20 miles and hour, dealer had never seen the problem before and was awaiting a fix from Audi engineering. Today is 16th and my car is at the dealer for almost 2 weeks now and I still do not have the vehicle. I contacted Audi and opened a case, case number 60373673, so far Audi is of no help. Dealer is doing excellent job of communicating with me but Audi needs to look at the issue as if this problem occurs on nations highway, people may get into serious accidents.
