My Ride: 2005 BMW 545i
I suppose it's better than it NOT coming on in the middle of the summer, but sometimes i just like to cruise with the windows down. My AC will come on even if the button is in the off position. It started doing this every once in a while a couple months back, but when ever i would turn it off again it would stay off. now the blower and AC will not stay off any longer than 5 minutes 
I am starting to feel like i am playing electrical russian roulette having an out of warranty BMW
car is a 2005 545i with 32,000 miles.

My Ride: 2006 525XI, Jet black on Dakota beige. Premium and winter packages. I consider myself a purist and intend to keep my car absolutely stock and shiny.
2008 328I Convertible, Sapphire black on beige interior. Premium package, NAV, iPod adapter.
Retired: 2002 325I, Titanium silver on black leather. Premium package. Absolutely stock and proud of it.
It could be that you have a loose switch or it could be that your car has the automatic humidity sensor and this is why the A/C comes on without your input. Maybe you just never noticed before?

My Ride: My ex-ride: EU '08 LCI 520dA. Space Grey, Sport Seats in Black Leather/Fabric Anthracite, Sport Steering Wheel, A/C with Extended Features, Hi-Fi Speakers, Cup Holders, Cruise with Braking function, Folding Rear Seats, Xenons, Park Distance Control.
The E39 and E60's I have owned had problems (three times) with the A/C sensor.
The part don't cost much but it's a bitch to change in the E60.
If the Search function would work on this site you would find a lot of my claims and replyes on the matter.
