I was in such a hurry writing down all of the info, I skipped 50. It means nothing. I have it listed as empty or something like that. It will always say 0. So that's normal.
As for your # 22, it could be? I believe I have the papers that list a pre 6/94 production 202 N22 read out values. I can double check. That would be interesting...
As for the rev in N and P. Is this for transmission protection? Why wouldn't BMW do this? But the engine just sounded so silky smooth revving up at 3800 rpm....! And the rev limiter was very smooth and sustained. I wasn't sure what was happening because the few times I encountered the rev limiter was in 2nd gear (manually in) and I forgot to switch it out!! It's not pleasant, quite jerky.... must just be 'cause the car's in motion!
Anyway, I'm going to compare the values of our pressures now. I hope others can give us their data too for comparison.
