Yep, i have a MAF error.
What I’ve tried:
1. I’ve tried to clean the MAF sensor, didn’t help.
2. Tried to give the connecter some electrical connector spray, didn’t help.
3. Tried to switch between MAF 1 and 2 (don’t really know what is what but I switched them), didn’t help.
4. A friend that previously had worked at Audi insisted that I backtracked on my latest JHM tune (the error happened shortly after an update), didn’t help (and I didn’t expect that!). 
So I guess that I’m down to wires.
The error is in engine module 2, but which of the two MAFs is it? Like physically. (drivers side?).
As you guys can see in the log, the MAF issue gives errors in a couple of other modules so no ESP and no adaptive cruise control. 
Don’t mind that it states that it’s an V12 it’s not.
