Vag Com

[JRWR]

I've read about the special VAG COM lead which would seem to be an ODBC lead with built in dongle so the Ross-Tech software recognises it and so enable full functionality.

 

I don't know how Ross-Tech are able to know the full VAG communications protocol. Perhaps it's in the public domain or perhaps they reverse engineered it after looking at the communication packets sent between a proper VAG service tool and a car. Either way, why can't we do the same and create our own application that lets people buy the 'cheaper' leads and use our developed application? I'm a software engineer and I could offer to write a windows application that would use a serial port/USB and let people with any sort of lead twiddle with the various ports made available on VAG cars.

 

Anyone got any pointers as to the VAG COM communications protocol? Any other softies out there who have comments on this as a project - it would seem quite straightforward to me but that's befoer I see the actual protocol in use.

 

Cheers
