Thanks again for the information.
Yesterday I all most bought this gateway http://shop.autopartsveghel.nl/nl/0...databus-audi-a6-s6-rs6-a6-allroad-q7-bj-07-11. When I asked the garage if they could flash the software for me to N they said that this unit isn't the right one. According to them to only unit that's gonna work is the Q7 26 pin with SW0071.
I would prefer a 26-pin-unit to a 20-pin-unit because than I wouldn't have to change the pins. But a 26-pin-unit wouldn't allow me 3GP and ACC, lane assist etc. which is a must for me. On another forum someone stated that one must use a 20-pin-unit hardware version N (instead of a hardware G in combination with software N)
A 26 Pin CAN gateway flashed to version SW0071 will definitely work with MMI3G+ as this is what I have in my 07 Q7 and everything is "almost" working perfectly. Means you don't have to worry about the battery regulator circuit (but teh battery level in the MMI 3G doesn't work). I have put in a version "A" of the Q7 CAN gateway as I am going to retrofit ACC next. As you can see, I have a single error which is for the Extended CAN not being wired up to the ACC or Lane Change Assist.
