Hi, was vacuuming the boot yesterday and, now "Boot Open" error stays on the dash. Tailgate closes and locks/unlocks without any problems, glass closes as well, just car thinks its not. Are there any reset tricks, like on side windows? F11 2010. Trunk is not automatic one. Also noticed, that rear wiper and screen wash nozzle doesn't work as well. When opening rear glass boot interior lights turns on, however when opening trunk, boot lights won't go on. Maybe it's wires to blame, but harness going to the glass (where wiper is located) are different to one going to the trunk. Can't be that both failed at the same time? Also disconnected the battery for 10mins, still the same. Plugged pc for errors, and doesn't find anything.
