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.

After turning my car on a gearbox malfunction warning appeared but said I could continue driving. After driving the message and service light eventually went off with everything going back to normal. The car appears to have a very common mechatronic unit issue that is part of the faulty dsg that Audi has put in the B8 S4 model.
