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.

One day the low oil light came on, brought it to carousol Audi in golden valley mn and they informed me about the oil sludge problem and told me to get my oil receipts ready. I changed my own oil and don't have my oil receipts and am now being denied a warranty coverage. Was told that I would have a new engine put in if I had oil receipts but will cost at least 9000 without the warranty.
