My only assumption would be something with the crank position sensor. Went to leave for work Friday morning, it started for 5 seconds, ran extremely rough and when I gave it gas it died. Wouldn't fire back up. Had it towed to a VW performance shop. Replaced that sensor and the battery distribution block so they could continue troubleshooting more. Called me a few hrs later with that news. I hope to find out more details Monday when I get an estimate.
I've had the car for 5 years and I am just about done with it. While I love it, it is so damn expensive to maintain and fix. Toying with the idea of getting a 2014 Focus ST or WRX.
