How would i determine with certainty that a coil has failed and which one it would be?

you need to scan it with vag com or another obdii reader to see which cylinder is misfiring.

Clear the code, swap out the coil into another cylinder. Start car, see if code changed.

Okay thanks! Not too worried about it though '11 w/27k stock(for now), except driving from TX to ME(not by choice) Guess I need to get a vag com, a friend recommended Ross Tech.

Yes. You want the VCDS Micro-Can from Ross Tech
