Did some googling. It's not the same. Very similar though. I found this:
VWVortex.com - MKIV door locks explained - why you're having problems!!!
The mechanism I replaced is still sitting on my workbench, so I took it apart. Tested all the microswitches in it, and they all worked fine. The circuit board is covered in some sort of orange glue. My guess would, it was a fix VW rolled out to address exactly what he found. Broken solder connections. For fun I'm going to resolder the whole board and test it. What could it hurt? May do the same on the passenger side.
