Jiggling side mirror..?

[Argenta]

Hiya!
My driver side mirror has seemingly snapped somewhere, at motorway speed the glass jiggles so much the rear view is fuzzier than on new years eve.

What usually happens here, and is it fixable..?

Had what sounds the same a few days ago. Passenger side glass jiggling at motorway speeds and looks like it could fall off any second. As far as I could tell the two options are:

1) Buy a replacement glass unit off Ebay. These are aftermarket and not identical to the BMW ones but seem to look fine when installed. Just be sure not to get the blue tinted ones as it won't match your other side. These seem to cost around £10.

2) Carefully remove the glass and re-glue in place with something strong like Araldite. Be careful as the adhesive pad behind the glass is actually the heating element itself so this cannot be damaged. I would suggest remove the entire unit (glass and backing plate) and then use something flat to carefully pry the glass away and loosen the small amount of remaining glue. Then clean up the glass surface and heating pad surface, apply glue and clamp together until dry. Reinstall into car.

I went for option two, and seems to be holding up fine for now!

As barnyg said - +1
I wasn't quick enough to catch mine as I shut the door and it dropped off
I used sticky pads (same ones as for number plates) not glue and bought the mirror from Halfords (more for speed of replacement really)
Think it was about £12-14 at the time

If its not already off carefully pull the glass away BUT DON'T pull the rubber membrane off the mechanism behind it.

Clean the rubber with any spirit based fluid (I use surgical spirit) then fix the mirror (or new mirror) using vertical stripes of double sided tape cover the rubber surface - if you do it this way if one strip fail its less likely to fall off. Use a hair drier to dry and warm the rubber before applying the tape.

Thanx a lot will look into this!
