This is all very interesting. And confusing. When you talk about bridging the pins, which interface are you referring to, the K-Line/VagCom or the ELM327, because I believe they are different. Also, what is common is the formfactor of the connector; it is "D" type. What would be cool is if a guru could take that "D" form factor, turn it on it's side so that the wide side is at top (call it wide-side top-line pins) and the narrow part of the D-connector is at the bottom (call it the narrow-side bottom-line pins.
Then, after stating which interface connector we are dealing with, describe from left to right, top-line, what are the pin numbers, and same for bottom-line. If I had this, I could do a definitive drawing of the connector and post it for others' benefit.
I mention this, because although I'm pretty savvy electronically and a computer guru, I've not found one thread that was able to describe this bridging process so that I can actually use it. (And damn, have I searched, because I have a problem with my 2000 156 V6 airbags.
