You may have a bad coil pack - try moving two of them around and see if the misfire follows the coil pack or stays at the same cylinder. If it follows the coil pack, get a new one. If it stays in the same cylinder, inspect your spark plug wires and make sure the plug is gapped correctly.

Definitely not the fuel pump. A fuel pump will either work, or it wont. It could be a fuel filter, though unlikely, again if it was clogged there would be nothing. Could be spark plugs/wires, a faulty coil pack, Could also be a handful of sensors (o2, MAF, are a few that come to mind). Does it have a manual transmission? If so can the car be started without engaging the clutch (in neutral)? If so check the 2 clutch sensors attached to the clutch pedal.
Probably a sensor. Go to Advanced Auto parts and have them pull the code. Then google it. Or check out Forums.vwvortex.com

get a new coolant temperature sensor.
the orginal black ones are faulty.
make sure it is the green topped one.
also do a normal tune up with spark plugs, clean the maf, maybe replace coils packs.
