Recently my Copen started buzzing when I opened the door. Headlights were off and the key wasn't left in so why did it keep buzzing? it turned out to be the foglight switch was on and even though the headlight switch was off it still buzzed. And never knew I could open the boot by holding the zapper down for 3 secs until I read it on here. Anyone else have any 'well, I never knew that' info?
