SI B41 01 08Body

Technical Service
SUBJECT
Rear Door Brake Connection Pulls out of the B-pillar
MODEL
E90, E91 (3 Series) produced up to 8/2007
SITUATION
The nut located on the inside of the B-pillar, used to secure the door brake fastener, may pull through the sheet metal on the B-pillar.
When this situation occurs, the door brake is inoperative. As a result, the door will not stay open on its own and has little resistance when opening and closing.
CAUSE
Material defect in the area of the door brake weld nut.
CORRECTION
Install a reinforcement plate in place of the weld nut.
PROCEDURE
1. Remove the inertia reel on the affected B-pillar per Repair Instruction RA 72 11 030.
2. If any sheet metal is not flush to the B-pillar, it should be repaired to BMW specifications.
3. The unpainted bore in the B-pillar should be protected using Wurth Self Etch Primer or the equivalent.
4. Test fit the backing plate (1) into the B-pillar. The plate will fit in the space between the inner and outer sheet metal. The plate should be oriented so that the threaded hole (2) is positioned to the lower outside corner, as shown. This orientation is necessary for the threaded hole to line up with the door brake fastening hole in the B-pillar.
5. Apply a thin bead of urethane (1) to the side of the plate, which will face the rear of the vehicle. The illustration shown is for the right side B-pillar.
6. Fit the backing plate into the B-pillar and align the threaded hole with the hole in the B-pillar.
7. Secure the door brake to the threaded plate before the urethane begins to cure.
