S211 Door mirror- intermittent fault

[jeremytaylor]

The nearside door mirror on my E320 has that most annoying of faults - an intermittent one.

When faulty it won't go to the right position after unlocking (using the mirror-fold function) or return to its right position after indexing in reverse gear. So I can't really use either of these functions with this fault. When I try to adjust it using the door-mounted adjustment, it moves in almost the opposite direction I want it to.

Yes, I guess it's only a minor fault, but when you're driving on motorways or around town it is a quite a good idea to know what is on your inside! And I want to get it fixed while under warranty.

I'm guessing at a faulty command module, although MB Brooklands (who have done all the servicing on the car) couldn't find a fault. They re-set it, but the problem still persists.

Any ideas, anyone?

I am wondering if the mirror is too tight on the fulcrum turning part, and that it is not returning to the locked position,, you could try spraying some PTFE (will not hurt the paint) into the swivel part of the mirror and fold it and unfold a few times to see if it frees itself off

The mirror housing folds in and out from the door OK, it is adjustment of the glass within the housing that is causing the problem.

Sorry about that. Then it is the motor loosing count, so that it cannot position correctly, and a new motor would seem to be required.
