Just checked my notes from workshop-manuals.com shows:
80ftlb for E90 of M12 bolts. (no angles, just that).
For E92, M10 bolt and 41 ftlb first stage, then 90 degrees additional. This means for E92 would be better not to reuse those bolts. If reusing I would be careful tightening. The additional degree usually means bolt is being stretched.
The tightening order is shown as first the front bolts close to front bumper. And then the other four behind. Going criss cross in addition to this would be helpful.
I have done this job on my 325XI E90, so I have these notes. Planning to submit a write up on XI, which is more involved.
All the torques are available on workshop-manuals.com but it is not very easy to wade through.
