It shouldn't, but I've heard that the clocks in BMW's reset when you change your battery. If that's not true, unless you mess up when hook it back up again and end up cooking the battery.... If you've never done it before, my 0.02 is to remember to hook up the positive first....

Either way, even reseting all that is cheaper than a new battery...

yes it will, it will reset the clock, the OBC to german, the date etc.

the code came in the owner's manual when the car was bought. If you bought it used, check the owner's manual (probably not there). If it isn't there, a trip to BMW dealer is in order.

It is different for every individual radio. Pull the deck and it may be written on it on a sticker. If not get the serial # off the back and call dealerships until you get one that will give you the code. They arent supposed to over the phone but just sling some bull and you'll get it..
