Why's that? Tooth#1 angle is whatever is required to get correct timing. It depends on sensor and wheel phasing.
On my 36-1 wheel, the correct tooth#1 angle happens to be 39 degrees.
I guess because BMW didn't put the crank sensor in a random place? ;)
for example: M50 vanos: 324 degrees (54 teeth)
M20: 84 degrees (14 teeth).
