I have a 2010 VW Jetta TDI. Approximately 3 weeks ago after the car had been parked for about 3 hours I got in and tried to start it but it wouldn't start. It had plenty of charge. The engine just kept cranking but never catching. I tried several times to start it without success. On the dashboard data screen it said "ESP error". I know that ESP is the traction system and when I looked for an explanation for this error message in the manual I couldn't find anything. I researched it online and all the references to this message had to do with failure with the traction control system while the car was in motion. I had the car towed to my VW dealership and they told me they had never seen anything like this before. Once they cleared the codes they car started right up and they were unable to cause the problem to re-occur. They even opened a ticket with some service center in Michigan. They were told by those folks to replace the computer module, which they did. I was without the car for 8 days. Last week the exact same thing happened It's back at the dealership and nobody knows what's wrong. Apparently some kind of "regional tech" is coming in to look at it. Have any of you run into this before?
