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.

2009 Audi A5 Owner Comments

problem #1

The water pump broke causing the coolant to leak and the "stop engine" warning light to come on. This happened while I was driving. I was able to put some water in the empty coolant tank - but all of the liquid leaked through. Steam was coming from the engine bay. The dealer advised that I put water in the coolant tank and drive to the facility as soon as possible. (it was about two miles away.) they diagnosed the problem as a failed water pump, causing the coolant to leak due to the pressure. Apparently five other vehicles (Audi A5 and Q5) were brought in over the past two weeks. Replacement part is back ordered and vehicle is still immobilized at the dealership awaiting part from germany. This vehicle had its 5,000 mile service less than a week prior to the incident.
