[s-cars] Aftermarket Coil Pack advice.....

[Varon H. Fugman]

I've been running 1.8/2.0 coils with a harness from 034 for something like 7
years now.  It seemed like even the newer revision 1.8 coils only lasted a
couple years in Stage I AAN usage, and the non-VW coils lasted even less.
However, since switching to genuine VW 2.0 coils almost 3 years ago I
haven't had to replace one in the S6.

Our '07 Jetta did have a 2.0 coil fail--and that was after having all coils
replaced with updated versions by a VW recall before we bought the car.
When the coil failed in the Jetta, I was briefly puzzled how I was going
determine which cylinder was the culprit--with the 2.0t FSI motor you can't
just unplug injectors like I'm used to doing!  I then realized I had a
perfect test bed sitting on the other side of the garage, so I temporarily
moved all four Jetta coils over to the S6 and quickly found the bad one.

I do keep a spare 2.0 coil in the trunk of each car.
