My son replaced the clutch on his 2000 A6, now, we don't have a spark. Had the flywheel resurfaced was told later never do that with the dual mass fly wheel. I suspect the pickup is not in sync even though the flywheel was marked and reinstalled in the same position. Did we screw up by resurfacing the fly wheel? I would appreciate some insight from someone who knows. Thanks...

the flywheel might have put on wrong. they say it will only go on one way, but it will go on multiple ways

I think the potential problem comes from the stepped flywheel and the pin removal. Anyone know if this can throw off the spark?
