The Map Light Mirror vibration can be eliminated by adjusting the foot
sleeve (Bulletin terminology) which is between the mirror and windshield.
It is a cylindrical plastic object that is approx 1.5 inch long and 1/4
inch long wide. It is hollow with a rubber tip on one end and standard
right hand threads on the other end. The threaded portion is only approx
1/4 inch long. From the windshield point of view that means the a
clockwise rotation will cause the foot-sleeve to screw into the mirror
(less contact with the windshield). Turning the foot-sleeve
counter-clockwise will cause it to unscrew from the mirror (more contact
with the windshield).
I just took mine off last night. I have a 325iX. First I removed the check
light panel by getting my finger nails under the bottom left and right
corners and lifting. Inside you will see the mirror arm going thru a rubber
grommet into the check light panel area. The mirror is held by two pins
that are pushed out to the driver and passenger sides by a spring. The
mirror can be removed by gripping the arm and firmly pushing/pulling it to
left/ right and up/down. The power wire is held to the spring by a plastic
tie. I let the mirror hang by the wire and then took off the foot-sleeve. I
inspected its design and verified that the thread was not stripped. To put
the mirror back on, I placed one pin into the body, I then used a 90 degree
brake adjusting tool to press in the remaining pin and mirror back into its
mounting hole. I then replaced the rubber grommet. In my opinion the
foot-sleeve is too short, and the threads are also too short. As the
foot-sleeve can easily get off center to one side or another. I unscrewed
mine to just meet the windshield, then straighten it out. The check light
panel top edges were insert first and then the bottom two corners just
click in position. After my road test, there was no vibration at all.
I hope this helps you,
