I replaced all the plugs on my car and it is still sputtering at low RPM in second gear...

How can I tell if it is the coilpacks that are bad, or possible a bad injector? More specifically how can I tell which one it is using the Vag if my car isn't throwing a CEL?

this is only at low rpms?

There would be DTC's stored (for misfires) but you may not get a CEL. Scan the car with a vag-com and see what codes are stored.

Actually posted about the problem when my car started running rough at times but it always cleared up. The check engine light was on so I took it to have it checked. The code was showing a misfire on the #2 cylinder. To be honest I was not sure how the cylinders were numbered so I switched the inners with the outters and had the check engine light reset. I took it out on the road and waited for it to spit and sputter again and checked the code once more. The misfire moved to cylinder #1. I think your check engine light would come on but I am a confessed rookie with Audi. However the first little sputter during this time my light came on instantly even if it cleared right up.
