Your wiper & rear fog won't work as the boot thinks it's still open.I'm having a similar issue with my 2011 Leon FR 170. Opened the boot then closed it and jumped in the car. Noticed the interior light stayed on and the dash was indicating the boot wasn't shut. When trying to close the boot it just bounces and can be lifted back up if you lift the rear wiper. Turns out the latch is still in the open position. I can flick it to the closed position but it immediately springs back to the open position.
I've noticed my rear wiper and rear fog light doesn't work but I thought hint that's due to the boot not being closed right.
I'm struggling remove the electrical connector as I can't see what's holding it and my fingers don't fit in very easily.
If it's only two torx screws holding it in I wouldn't dream of paying someone to fit it. Seems a bit expensive if the parts £91 when only a year ago it was £61?
