Hey man, sorry to hear that. Issue isn't battery, it's just when someone sits in the middle of the back seat, so has to be something like a short somewhere. In the end I just put the armrest down in the back so nobody can sit in the middle .... doesn't happen anymore since I did that. Not a solution but it's good enough to keep my sanity
Hey Etch.... I had the same problem on my 2012 audi a6 just after purchasing the vehicle (bought it used). You are completely correct by saying that it is every time someone sits on the Centre seat in the back seat. There is a control unit underneath the seat which causes this issue every time people sit. The wiring to the unit goes loose and causes a shot, which results in all the many faults on the dash.
Please take the car in and have your auto electrician properly reconnect the wires to the unit and you will be sorted.
