Well I found out the official specs from BMWUSA for the hood gap on 2006-2011 sedan 3 series models. I picked mine up last Tuesday and the Technician showed me the specs for the hood gap and it is:
3.5mm +/- 0.
Mine is at 3.5mm exactly right now so they said even under OEM warranty since its in spec, they can't touch it.
Just thought I would share this with others.
