2003 Jetta tdi stalled while driving - had driven it 14 miles into town, engine temp was reading 180 degrees or so, just approaching the on ramp to get on freeway when the engine stalled - got over to shoulder - tried to restart - engine turned over but wouldn't catch, after 3 attempts I lifted the hood and checked the fuel line- looked good - I got in and turned it over again - engine started and ran for about 4 seconds and stalled. I called a tow truck - they said they would be there in an hour. After 20 minutes I had a hunch the car might start - I turned it over and it started immediately - I cancelled tow and drove it to my son's house a few blocks away. I have tried starting it a few times over the last week and it starts and runs just fine. I'm afraid to try driving it back home as there's no shoulder on our river road for 12 miles. I haven't been able to find anything wrong that may have caused the stall. I recently removed and cleaned the EGR and inlet manifold. The turbo actuator was working so I did not clean it - I replaced all the vacuum lines at that time, also the air and fuel filters. I had done a few test drives and the turbo was working well (car had been in limp mode before I cleaned the inlet manifold). This was the first longer drive. I'm wondering if gunk from the turbo might have come through and caused the stall. I'm a total novice on this. Any ideas?
