Found a few internet entries for P301, P302 etc etc which were difficult to cure. I didn't find a resolution while browsing!

I did come across this though :

01 02-07 10/25/02 Golf, Jetta, Jetta Wagon, New Beetle w/ 2.0L (AZG adn AVH), 2002 Misfire, Incorrect Cylinder Identified by ECM Software Fault codes P0300 along with P0301, P0302, P0303, or P0304 stored in DTC memory. (ECM reports incorrect cylinder that misfires.)

I would have your plugs out one at a time and review their condition. This may indicate which cylinders do have problems if the above applies to your car.

If certain cylinders aren't firing properly then it's probably a coil pack change.

With these error codes not the AMM, or catalytic convertor or lambda sensors or an intake leak although there is no harm in checking all pipework.

good luck, Ian
