Really annoying vibration from rear view mirror

[omega1]

hi all, I have a W203 2003 C220 CDI and the rear view mirror has developed a really annoying vibration at certain RPM and if I dont get it fixed i'm going to end up knocking it off! Moving it cures it for a while, but then it returns again.

Anyone had this and what to do? im a bit wary as I know it has stuff at the back (ligth/rain sensors?)...

thanks

Does the engine run well? Any missfires?

hehe, when i'm blasting the music everything vibrates!

BlackC55, no, it doesnt appear to be, but could be i guess, i only have to move it slightly and it seems to be Ok for a while, i was wondering if anyone else had experienced this and could suggest anything, im a bit cautious as it has electronics on the back, so need to be careful. thanks
