 I have been down the coil road with VW.  They will not admit that it is a major problem with their car.  I have almost been stranded twice with the coil problem.  Once I was at the dealer & they told me I would have to wait until the following week to get it fixed.  It is a really simple thing to replace .  I called a friend (Mechanic)  & he knew right away & told me to buy a coil at the dealer & he talked me through changing it.  It was a trial & error method because I didn't know which one of the 4 was bad.  It turned out to be #1 coil.   2 weeks later # 2 died.  I replaced it & the other 2 & have solved my problem.  I hope the new ones are more reliable! Also had to replace a front axle
