Need '01 Jetta GLS Engine Code

I'm trying to replace the cam position sensor and the ignition coil on my '01 Jetta GLS. Apparently I need the engine code to get the right parts.

Where would I find the code?

You will need an OBD-2 scan tool. You could take the car to a shop and pay to have the codes read...or for about the same price you could buy an inexpensive code scanner and read the codes yourself and own the tool for future use.
