SUBJECT
Buzzing Noise from the Door Panel Pocket
MODEL
E82, E88 (1 Series) produced up to 9/2008
SITUATION
Intermittently, while driving over rough surfaces, a buzzing, clicking, or cracking sound is heard from the door panel. Specifically, the noise is coming from the door pocket area.
Pressing on the upper edge of the door pocket while driving the vehicle over rough roads will eliminate the noise.
CAUSE
A loose plastic weld on the back side of the door panel
CORRECTION
Repair the loose plastic weld on the door panel.
Replacement of the door panel is not necessary.
PROCEDURE
Remove the affected door panel per Repair Instruction RA 5141000.
Lay the door panel on a hard surface for the following work to be performed. The surface should be covered to prevent damage to the finished side of the panel.
Inspect each of the plastic welds in the area of the door pocket. If any play exists between the welds and the door panel base support, each of them will need to be repaired.
Heat the affected plastic welds using an electric heat gun (set to high). The heat gun should be held about 1" from the weld to properly heat it.
Each affected weld should be heated to the point that it softens, but does not melt.
Remove the heat gun and use a blunt object (such as a 13mm socket) to press the weld securely to the door panel support.
Allow the weld to cool and then ensure that the weld is no longer loose.
Reinstall the affected door panel.
WARRANTY INFORMATION
Covered under the terms of the BMW New Vehicle Limited Warranty.
