This problem has started since I loaded a mattress in the back and had to shut the boot firmly to shut it. The mattress has been removed. When I lock the car the boot warning flashes on the dash and the hazards flash even though the boot is locked.  Sometimes if you leave it unlocked it will lock up on its own then the flashing starts up and the alarm goes off. If you lock the car then unlock the boot with the remote the flashing will stop and there is no boot open message on the dash-the boot is unlocked all the rest is locked. If you then open the boot and shut it the flashing kicks off again.  I do not have any form of scanner.

So, at the moment I can lock the car but have to unlock the boot afterwards to stop the flashing but then it locks the boot again and off we go again. Now trying leaving the boot unlatched with the boot open warning on the dash, hopefully the alarm won't go off now.

Any offers?

Further action taken.

Further update, if the boot is not fully shut and then locked there are no flashing lights so at least I can lock the car up, but I have to shut the boot fully before driving off. Looks like a new boot catch in due course. 

Further update, shut the hatch properly, locked, back to normal. 

Good to hear you got it sorted, well done mate.

It sorted itself, gremlins in the electronics.

@peter3197The boot latches sometime need resetting in terms of it fitting; the fit is very tight and can cause the boot not to latch sometimes.  Ask your dealer to adjust your boot latch when you are next there.
