If anybody has technical information on the Motronic system used on the a4/s4/tt (both drive by wire, and earlier) or obd II in general could they please email me? I am trying get all the documentation I can in order to help develop a truley affordable pc interface / method of monitoring our cars systems.

Any, specs, pics, links, wiring diagrams, part numbers for sensors, software, ecu's etc., interface information for VAG and diagnostic tools, aftermarket and factory diagnostic tool p/n's and vendors, etc.

Thanks in advance...
