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.

2012 Audi A4 Owner Comments

problem #1

A4 4-cyl

  • 3,956 miles


At approximately 1000 miles on the odometer of my 2012 Audi A4 avant quattro, a strange noise began from the front area of the engine. The noise happens at the first startup of the engine regardless of ambient temperature. After about 2 minutes when the engine idles down the noise stops. Different Audi technicians at two dealerships have diagnosed the noise as 1) cam tensioners, 2) a bad bearing inside the cam case, 3) secondary blower motor and, 4) lash in the vvt system. None of the technicians have put a wrench on any of the named components because, according to the dealerships' service managers, Audi usa will not authorize repairs. According to Audi usa, the strange noise is a normal function even though Audi customer service cannot explain why the noise was not apparent for the first approximate 1000 miles of driving.
