Hypathetically speaking, does anyone know of any home made circuits, or devices that can be purchase don the internet that can be hooked up between the car's computer and the odbII connector? It would be interesting to see what the dealer sees when they hook up their equipment to say, determine what errors are in the computer, and umm.,., program keys ;-)
The interesting part is, the dealerships probably have an encrypted connection going over the internet back to VW to obtain the necessary information to program key transponders. The information being transmitted from their computer system to the car's computer is probably being transmitted via RS232 signals at various baud rates (unencrypted). If one wanted to find out the importer code, and other pertenant information to program their own keys, that would be the way to do it.
Hypathetically speaking There are keyboard loggers out there like the one on thinkgeek that can capture (via hardware intercept) the various charicters entered in on a keyboard. The following link is for refererencing the technology:

I'm not an EE, i'm just a computer security type of guy. Given that it's a serial communication that occurs in order to say perform diagnostics or program keys, I would assume it would be pretty easy to caputre the raw data, then dig through the data-stream to see "interesting" things.
Does anyone have any information on the pinout of the diag port, voltages, etc?
Just thinking out loud, but this seems like an interesting project. Especially if it can be added inside the dash between the diag port and the computer...
