I've had some partial success however it's not good news for empeg OBD. I have built a commercial BMW only interface and using some really really really crappy PC software that I ... ummm ... found somewhere I can talk to the car.



I can get the live data and read the fault codes for a few things but there's not as much info as I'd like it would seem.

It also means that I'd have to work out the protocol (again) to talk to the interface I built.

So unless you have a BMW what I have now is useless to anyone else

I'd still like to get some kind of more generic interface going so I guess I'll snoop what's happening on the bus and see if I can figure out the "standard"
