Most of the coils fail when first purchased used. Or if you have taken it in for a detail.
The dealers clean the engines and on many occasions, water has gotten into the coils, 1, 2, or 3, whatever. I would replace all at once if this is a problem.
Hope this helped.

What engine do you have in your vehicle? If it is a 1.8T, your coil packs are on the very top of the motor. There are 4, one for each cylinder. Once you pull the plastic engine cover off (if you still have it) you cant miss the coil packs.
