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.

2004 Audi A6 Owner Comments

I am writing about my 2004 A6 avant, which has 78,000 miles. At a recent oil service at an independent garage, it was suggested that there was a problem with the catalytic converters. Exhaust was leaking from both sides, I was told. I took the car to my Audi dealer, where they checked the exhaust system. The mechanic who examined the car concurred that the catalytic converters needed to be replaced. Under a federally mandated warranty, the catalytic converters are covered for eight years or 80,000 miles. Yet the dealer has declined to cover replacement because the "check engine" light was not on. I was given a repair estimate of $2,400.
