Tailgate won't open (but now it does) now it doesnt Hi all, had a bit an issues the past few days, I couldn't open the tailgate, also noticed that a few days ago the indicators only flashed three times when locking (not the normal 5)and eventually wouldn't flash at all, although the doors would lock. Tried using the other fob and the key, read the bit in the manual about super locking. Was resigned to taking it to the dealer and then suddenly this morning it all started working again. Can anyone suggest any maintenance I should do to the rear lock mechanism or checks, there was nothing trapped in the tail gate and there was lubrication around the hook mechanism. Or has anyone seen this before?
