I have a 2006 TDI Special Edition and have had 2 recent situations with my car stalling on me. The first time was driving through a very wet snow storm near East Glacier, MT. My car suddenly stalled as I was traveling at approximately 60 MPH. I was able to pull off the road onto a Farmer's access road to his ranch. I tried a few times to restart the vehicle and it just sounded like it was not getting any fuel. I then called my mechanic, John at Celtic Motors in Kalispell, MT and he advised waiting for a little while longer to see if it may start again due to the wet conditions. In the meantime, I started making calls to arrange for a tow truck to pick me up. As I was waiting for the tow truck to call me back to confirm my location, I attempted to start the car again. It would start and run for a short time (5-20 seconds at most) then stall again. After approximately 30 minutes since I had to turn off the road, it had finally started and I let it idle for at least 10 minutes without the car stalling that I felt it may be fine to start driving again. I called John at Celtic Motors back and discussed what had transpired since my last conversation with him 40 minutes prior. He stated it should be fine and it was totally fine until I recently stopped at the car wash to wash some of the sand and hydro chloride off that the MT HWY's are always covered with. I used the Engine cleaner which is a very light green spray and then rinsed it quickly with the high pressure rinse. The car started immediately after I was done washing but was only able to get a 1/4 mile from the car wash when the exact same symptoms appeared as I was driving through a wet snow storm. The car started to stall and eventually was able to coast into a farmer's entrance to a field. I waited for at least 30-40 minutes trying to restart every 10 minutes or so. The car did not show any signs of restarting this time so I had my wife come pick me up thinking the car may start again if i left it overnight as I had read in some of the posts on this thread. The car did not start the next day and I had to have a tow truck come pick up the car and take it to Celtic Motors. Shortly after dropping the car at Celtic Motors, John attempted to start the car and it started immediately. My guess is the air passing through the engine compartment as it was being towed on top of a flat bead was enough to dry whatever sensors were wet was what made it start. The car is running fine again and it's still a mystery!!
