2019 e450 rattle in mirror unit.
I know this is a long shot, but... in the last couple of weeks I have noticed a subtle but constant rattle that seems to be coming from the rear view mirror unit. It’s big since it has all the sensors in there, but I can’t pinpoint it. It could be from the header area around there too, but I think it’s most likely in that set of plastic parts. Has anyone else had anything similar?
it’s a 2019 e450.
thanks

1 rattle turned out to be my sunglasses in the holder, so that's an easy fix :-)
the 2nd rattle is as per attached. it was the headliner. - i put kleenex in between to make it stop.
but not sure if your rattle is the same as you say it seems to come from the mirror....

I just had my car serviced and asked them to check this. The mechanic confirmed it (was my lucky day because any of my cars are on their BEST behavior when they are at the service, making me look like an obsessive complainer). This was the diagnosis:
- ASPIRATOR MOTOR IN THE OVERHEAD CONTROL PANEL IS NOISY -> REPLACED OVERHEAD CONTROL PANEL.
So far I have not heard the noise.
