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.

My vehicle didn't start after 12 days of sitting, it also had a rough start (no start followed by driver assisted start) after sitting for about 9 hours. I believe the rough start was a related to the no start. Date of no start: 12/29/10 location: Philadelphia offsite airport lot mileage: > 20,000 got my 20K service two days prior to parking it on Dec. 17. it snowed 22" on the 19th and then throughout the rest of the days it would thaw, freeze, rain etc. It rained approximately 3" during that time. Got back Dec. 29th at night. The engine tried to crank once and then didn't do much afterward. Had it towed to the dealer (VW of langhorne) and they found water in the cylinders by removing the glow plugs and manually cranking the engine. After a couple of days messing with the dealer they finally dried out the engine and found water in the intercooler lines. Ran fine until 2/1/10. Dealer had me pay for their time because "the only way this could happen is if I drove through a puddle or if it was in a flood". they are wrong. The parking lot is not valet (I kept my keys) and they have a snow removal service. Snow was not plowed into or on top of my car. No other water damage was seen in or on the vehicle anywhere else. Date of no start: 2/01/10 location: Northeast of philadelphia mileage: 21,000 codes: None known significant weather before no start: Cold, dry took to dealer (what was done): No ambient air temps: High 36 (F) low 21 (F) Jetta started fine in the morning 6:30am. Left work at 6:00pm and did not start. The sequence: 1) crank but didn't turn over 2) got it to turn over and start about 1 min later, no message on mfd 3) kept foot on accelerator in neutral at about 1300 RPM for 30-60 sec. 4) ran fine on 30 min drive home this is an unsafe condition that could result in significant problems if it takes a long time to get a tow in the winter.

I bought my brand new 2009 Jetta tdi on 5/28/2009 and 2 days later after I had only driven the car for 200 miles, the air conditioning stopped working when the car was sitting still. I opened the hood after I got to my destination to realize that the cooling fans were not working at all. They would not even come on to cool the engine. This occurred on a Saturday, and the VW dealer where I bought it was closing in an hour. Their master tech agreed to stay until I got there and he ran some tests on it, and told me he simulated a severe engine overheat and the fans still did not come on. He said the car could not be driven and it would have to stay at the dealer. He said the fan relay was faulty and would have to be replaced. Then Monday morning the service manager whom did not believe the master tech decided to drive my car with a non-functioning cooling system to see if he could replicate the problem. He called me to discuss the fact that the air conditioning worked while he was driving to which I said it will when you drive it, however, it does not work when your come to a stop because the fans do not turn on. He finally decided after a day of wasted tests to order the part. I finally got my car back today after they had it for 5 days of the first week I owned it. I am so glad I purchased the 100,000 mile warranty, because that sort of problem after 2 days of ownership does not say much for VW. Everything was covered under warranty, but I was still without my car for just shy of a week. Diagnosed part= cooling fan module failure.
