Folks, any help would be appreciated. Just bought a 2006 Jetta TDI and it occasionally will start then quickly stall. After about 15 minutes it starts just fine and stays running. This usually happens when it has been running fine, turned off then needing to be restarted a few minutes later (like the time it takes to run into a convenience store and come back out). I've checked other forums and it is a well know problem but no thread I've read gives me confidence anyone knows how to acurately diagnose and fix the problem the first time. Also, no two fixes I've read about have been the same. There must be a simpler and more reliable way to make this problem disappear. VW dealerships can't possible be as inept as the forum contributors make them out to be. Any thoughts on where to start? Anybody??
