Hi all, 2000 Jetta 1.9 TDI, ALH, 300 000 KM on it, timing belt/waterpump changed 40 000 km ago Yesterday I encountered a "fun" problem. Was driving on the highway at 120 km/h, on cruise control, when all of a sudden the engine shut off. No warning, nothing else turned off - just the engine. It will crank fine, sometimes even starts normally for one second but dies immediately. The immobilizer on the dash is not flashing, glow plug light working fine, gauges all working fine, just can't keep the engine running. Unfortunately I was 150 km km into a 1000 km trip and got caught with my pants down (so to speak) when this happened. More or less caught in no man's land, I had to call for a tow and it was dropped off at a VW dealership. No fault codes. Below is some more background info. It's been cold, -20 celcius. Car did not start first thing in the morning (even plugged in) and I had no one around to boost it so I put a battery charger on it and also waited for the ambient temperature to warm up a bit. After about an hour on the charger, starter was able to spin fast enough to start engine. Headed off and after about 140 km I stopped at a gas station to fill up the tank. I actually left it running while filling up and headed off with a full tank. 10 minutes after filling it the engine cut on the highway. I am certain I put diesel in. Initially dealer technician thought was that the fuel had gelled, so they left it in the shop all night to defrost. Come back this morning, still same problem - cranks, will start and run for 1-2 seconds before immediately shutting off. Then they decided to check for fuel contamination - result came back that the fuel was OK. No fault codes according to them. They want an additional 2 hours to attempt to diagnostic (first hour was inconclusive). Up until yesterday, the car had been running fine in these temps, never had an issue with bad fuel or gelling. Any thoughts? I have never brought a car to a dealership before, but given the situation, I figured it would be best (hopefully someone there is familiar with TDIs). I don't really have time to mess around, I need to head back to work (where I was going). Any thoughts?
