I'd do a physical request to the trans (address 7E1, response should be at 7E9) with PID 0x0D. Only the trans will respond. As for the source of what it responds, I don't know. If I were in VAG's shoes, I certainly wouldn't bother with software to independently compute vehicle speed from the output shaft speed (which requires the transmission be coded for the various wheel diameters in all its applications), I'd read it over CAN just like the ECM does. But then again, I'm French, not German The good news is you should be able to tell right now, by using the OBD2 mode of VCDS while at speed. That should get you both speed from the engine and speed from the DSG, and let you decide if what you get from the DSG is worth rebroadcasting.
