all 4 of my ignition coils went out and vw's manufacturer of parts kept replacing them with bad coils. they knew about it but I'm sure it's a great way for them to make money. This happened 1 year before VW finally sent out a recall letting me know that there was a problem. Lucky me, I got to pay for it out of pocket and because I chose not to go to the dealership (since they like to exploit and rape you for any services you have done there) they would only reimburse me for the parts and not the labor or the 3 times I had to have my car towed over for repairs. Thanks a lot VW. You can be sure I tell everyone how poor their service is and how I will NEVER buy another VW as long as I live. Poorly made cars and even worse customer service.

ICM failed, replaced with "huco" brand for $120 instead of the dealers' $350 part. it has lasted over 60k miles.
My Ignition calls 1st went about 2 months ago and 1 was changed. Now I'm back at the mechanic with another coil shot, and I will be changing all of them. I am becoming very unhappy with the cost of maintaining this car.
