Hi
I have an electrical fault on my BMW i put a new batterie on the car, and over night it drains it to 25% so the car could not start
what would be the cause, their must be a drain on the system some where, when the car is turn off. no lights where left on, so I'm thinking the factory fitted alarm ? any thoughts

Where do you get 25% from if you don't mind me asking?

You can have an electrical fault virtually anywhere in the electrics that could caused that.

You need to close the car up, switch everything off & get out a multi-meter & do some testing to see which circuits/fuses are flowing what current.
