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.

2001 Audi A4 Owner Comments

problem #4

Jan 042006

A4 4-cyl

  • Manual transmission
  • 89,000 miles


I have an Audi A4 1.8 T and the hydraulic timing belt tensioner lost its pressure witch made the timing belt slip, forcing the pistons into the valves and bending them, causing the engine to basically self destruct after only 89000 miles when the owner's manual only recommended changing the timing belt after 120000 miles. I called Audi, and they told me they would fix it for $5,000 and don't feel I should be the one paying for this when there was nothing I could have done to prevent this problem.
