One idea would be to take it to a shop that has the special VW scanner and either scans live data for free, or doesn't charge much to do so. Live data will show what's going on when the code is set.
You said you'd swapped the coil packs around. What happened when you did that? Did the misfire code follow the coil pack, or stay on #3?
Have you checked the injectors and coils with a noid light to watch how they're pulsed?
