My Ride: 325ci 2001
coupe latch and regulator replacement

I just did this. 2001 325 coupe.
My actuators never worked, so I used my key to get in, and of course the lock circlip broke off and fell into door.
So when my used parts, actuator and lock came in from Bavarian auto recycling, I got busy.
Job time:3.5 hrs.
Cost; Actuator $75
lock $75, arrived broken.

Door panel removal, easy except that they are all torx screws, and pull the airbag insignia off door panel, hidden screw there.
Once you get panel off, airbag 3 10mm bolts. I took neg cable off before removing airbag, to get foam backing off.
Note, You DO have to take the window out...very small torx screw holding window in reg.
Hook neg cable up, run window up so you can see both of these screws. Note: these are left hand thread, turn right to loosen.
Take the rr window bolt completely out, it goes thru the glass, then push black plastic grommet through window till it falls in door.
Note orientation of rear glass holder, it is adjustable at the guide.
Pull chrome out window mld off.
Lift window, and mine hung up at rear when the female nut ON THE GLASS at bottom of glass squeezes through top of door.
Note, oem regulator had aluminum holder where cable normally jumps out and zip ties goes. No place to put zip ties, I tried.
Take rear reg rail out and let dangle.
Note: when you let it dangle, the part the glass sits in is 3 pieces that make it adjustable and mine fell apart, in door. Not broken, it took some pics from this forum to put back together.
Replacing the latch is a breeze with rr reg rail out. Plug and play. 2 weeks later, elec latch works fine, what a relief.

I never unplugged airbag, just neg cable off and on.
The hardest part of this whole job is reassembling window holder that torx screw goes though after it falls apart. #10,11,12 in regulator pic is where the headache is.
Elec lock works, window works, all is good.
