This is a 2014 Volkswagen Jetta sportwagen tdi (turbo diesel) I commute from charlotte, nc to detroit, mi approx once every 3 weeks. I travelled from a cold (15f), wet climate, to a warmer climate (34f), and parked my vehicle overnight. The next morning, the car would not turn over, and acted like the battery was dead. I checked the battery, and it was 13. 9vdc. I continued to try to start the vehicle, each time the starter motor just making a grinding noise and not turning over. I left the vehicle for approx 20 minutes, and tried again, when it eventually turned over, all the warning lights on the dash came on, and the car idled very roughly at aprox 400 rpm. I tried to increase the rpm, and eventually (5 minutes of gently pushing the accelerator) it got up to 800-900 rpm. I tried to drive, and the car stumbled and sputtered for a while before getting up to normal speed. This has happened 5 times total so far. 3 times dead battery / hydro lock situation occurred 1 time the car ran roughly, and then when I pulled out onto the main road the car stumbled, died, and would not let me accelerate. I quickly put the hazard flasher light on, and somehow avoided a collision with the cars around me. 1 time the car ran roughly for approx 5 minutes, then ran smoothly the rest of the trip. I'm worried that I've damaged the engine.
