Any clues why?? Not sure you can turn it off permanently (even via fusebox) without causing knock on problems else where.
If there's something up with an interior sensor though, I'm sure there's a button to turn them off you can hit when you get out the car each time before you lock it. Thing is, I can't remember where it is (I know in the golfs
)
Will try and have a look when I'm in tonight??
