This is really dangerous! Coils 2 and 3 ( out of 4 total coils) failed. My car lost all power in acceleration - this is really bad when you live in a crazy traffic city like I do - Houston! I almost got killed because the car, which is usually peppy and full of power, suddenly wouldn't go. It also felt like it was going to stall at any moment and was shaking all over. It was a mess! Fortunately all I lost was the $50 co-pay and my time at the dealership. Vw's are scary!
