SOURCE: Error Code
P1300 Misfire Detected, Fuel Level Too LowIf the low fuel level is not the case check for a dirty heat sink for the ingintion/igniter module or any other source of a misfire, if you have run out of gas this could cause the code as well

I note that you posted your question 14 Feb 09, so happy belated Valentine's Day! Anyway, I own a 2004 VW Passat 1.8 and am currently facing the same problem (EPC light and check engine light on) and subsequently, I coded it out, which was P0322. I took my other vehicle (more reliable) into the VW dealership in Olympia Washington. I was going to replace the EPC sensor, which typically handles what is sent to the car's brain, telling it how much gas it needs to run. However, the technicians at the dealership told me to code it out before investing any money without knowing exactly what should be replaced.
I took the code and determined the "crank sensor" was defective. If you call around, you should be quoted anywhere between $48 and $90 respectfully. If your VW was lurching like it was missing for a split second at a usual speed, or died at stops, then I would say you were experiencing the same problem I was having. Hopefully, this will fix your problem? The part is pretty inexpensive, but I think what VW charges to replace the sensor, is highway robbery. Anyone in your family mechanically inclined? Good luck!

as per vw, you need to check transmission oil level., not an easy thing to do. if transmission oil level ok (no dipstick on these by the way). it is a mecahnical fault.
