We just took delivery yesterday and the seat won't open with the remote. We can hear the sound but nothing happens and pulling up on the seat shows it's still latched.
I searched and found clues to open from inside the boot, but couldn't figure it out - there seems to be something loose in there though.
I took a photo with a hand mirror - the red thing seems loose or broken.
EDIT - UPDATE -
I've been playing with this some more and it's clear the cable release (red end) is detached from whatever it is supposed to pull. Time to head off to the repair shop I guess. :-/ I was able to open the seat manually after some experimentation on where to push.
