I do very much appreciate all your help and I'm sorry if I wrote too much. I do spend a LOT of time taking the pics, editing them, annotating them, combining them, and in general, trying to improve the knowledge that is on bimmerfest.
I agree it's in no way efficient for me or for you, if you already know the answer or if you've already provided the answer in this or other threads. In fact, I probably spend twice as much time documenting the problem and the fixes than I do on the fix itself. So, I agree on the efficiency problem.
