This doesn't exactly answer your question but VW had a recall on these about a year ago and would replace them for free, don't know what they will do for you now that you have after market coil packs but it maybe worth a call to your local dealer.
What brand of coil packs and from who are you buying them? Just because you are buying coil packs from an auto parts store doesn't mean they are of good quality.
Have you had your car scanned for codes? it may help in diagnosing your problem.
