Guys - The plastic underside hood / bonnet vents always crack at the attachment screws from overtightening or become brittle over time due to the engine heat or how fragile these pieces are.
Good news - You can still buy a brand new one from BMW = left side ONLY if you want to shell out almost $50. The right side is NLA
You have a choice to remove them altogether or fix them for nearly free.
Needed:
1) Thin sheet of aluminum (taken from you metal scrap pile)
2) JB Weld (we all have a tube of this stuff in our garage) or equivalent epoxy
3) Tin snips to cut the aluminum sheet
4) Clamps
5) Satin black plastic compatible paint.
Time: A few hours only
Here is the broken vent, and I have made the new aluminum tabs:
Epoxied and curing:

These would be a great Item to have 3d scanned and print them off on a 3d printer.

Great idea!
I'll bank this one once I get to that point.
I did a similar repair to the air ducts that channel air to the rotors. These attach below on the right & left below the battery bot and window washer fluid tank. The plastic mounting points got busted up after 42 years of service.
Using thin sheet metal I cut and formed the shape. I used Por Patch because it is what I had on hand and it claims to stay a little bit flexible- we'll see about that. used the adhesive to attach the cut/shaped sheet metal and used clothes pins to clamp. After the cure time I put a few rivets in for good measure. I am not yet at the time to attach back on the car, but I feel it will work out just fine.
