Guide overview

Before you begin

Replacing LED unit in BMW wing mirrors which functions as an 'auxiliary' turn signal (in addition to the main indicator lamps).

Step 1

Repair step

⌕

Gently use a car trim tool to pop the mirror glass off its central holder. You shouldn't need to detach the cables to it, as it can just rest against the window after removal.

Step 2

Repair step

⌕

There are three plastic clips holding the front wing mirror trim in place. Squeeze the plastic 'legs' of the clips to release and then push forward. With a little bit of persuasion, you should then be able to slide the plastic cover off.
