Actually found out yesterday why the alarm was going off......the drivers side rear door isn't locking!
All buttons on all doors go up and down with the fob and passive lock on the drivers door.
All looks good and the alarm will arm after a time delay - walk up to vehicle without fob - try DS R door - opens - voila - alarm goes off.
No other doors will do this.
Very tricky because if you visually check you can see the buttons are all down - easy to walk away thinking it is locked and armed.
Off to dealer this morning to sort.
