Was reversing our other car in last night and the wing mirror hit the brake light on the boot on the driver side of the Alhambra.
This morning it was fogged up and had water ingress. I've ordered a new replacement. 155 euros or so from autdoc

Could anyone tell me how to remove the broken one. I've googled it and cannot find any video on it.
Expensive mistake on my part but coulld of been worse also put a small dent just above the light as well but its tiny.
