audi coil pack

i think one of my coil packs has gone on my Audi a4 2.0 2002. The engine is very lumpy with no power? Put my VAG COM on and got the following codes 16684 (random Misfire) & 16886 cyl2 Misfire? Swap coil packs around and the Cyl code changed? Could this be down to one coil pack or something more sinster???. Does any know where you can get coil packs from or any Audi parts for that matter ? Searched the web but only getting breakers?

Any help would be appreciated

I thing coil packs have a 5 year warranty.... Its worth checking. You might be just in time.

Thanks Mate
