Its usually from the center out in the next most opposite bolt (star) sequence. ie. if its a 14 bolt head 1-7 top, 8-14 both from front it would be like 4-11-3-12-5-10-6-9-2-13-6-8-1-14-7. you just want to avoid tightening a bolt outside a non torqued bolt to prevent head or gasket damage. torque specs are done in degrees, ie 44 ft/lbs, then run it 15 min then tighten another 33 degrees, then run it another 10 minutes and final torque another 25 degrees.

Torque sequence: ----------------- there are two rows of fasteners and you need to start with the middle 2 fasteners first and then work your way toward the front and back in steps. Step 1: torque head bolts #1,2,3,4,5,6,7, & 9 in sequence to 10 Ft/Lbs Step 2: torque head bolts #1,2,3,4,5,6,7, & 9 in sequence to 20 Ft/Lbs Step 3: torque head bolts #1,2,3,4,5,6,7, & 9 in sequence to 29 Ft/Lbs Step 4: turn all head bolts in sequence an additional 90 degrees Step 5: turn all head bolts in sequence an additional 90-degrees recheck final torque in sequence. Fasteners are supposed to be replaced if they are removed since they are torque-to-yeild fasteners.

7 - 5 - 1 - 3 - 10
front
9 - 4 - 2 - 6 - 8

the mirror glass will just pull away but to remove the complete housing you must take off the door panel and pull away speaker cover at top to exxpose the bolts

BMW cylinder torque setting all models

According to my service manual as follows.

Cyl head to engine block (torx e12 M10 bolts)

Stage 1 30nm (22 ft – lb)
Stage 2 + 90 degrees
Stage 3 + 90 degrees

Cyl head to lower timing chain cover 10nm (89in – lb)

The tightening sequence is from inside to outside crossover as normal. Loosening sequence is from outside to inside crossover. Remember to set torque wrench at low setting and work gradually up through the whole sequence until you get the desired torque.
