Thanks to the guide I got my brake lights changed. Both were out at the time and only the spoiler one was working in my avant.

Accidentally dropped the bolt inside the car when taking it off and had to screw the metal list at the back of the boot out to get the bolt back.

All in all took me 35mins at the first time. Second time should take less than 15mins since now I know how to do it.

Thanks again for awesome guide.
