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.

A6 6-cyl

Faulty ignition coils (so far 3 out of 6 cylinders went bad). On three occasions after starting and putting the car into the gear, shaking ensued and the "check engine" light turned on. The car had to be towed each time to the dealer where the faulty parts were replaced.
