location of fuse box for a 2006 bmx525xi

I have a 2006 535xi BMW, I was in a car accident and rear ended someone. My airbag deployed but there was very little exterior damage. Is my car totaled?

when i start the car it reads 39liters pre 100km and the goes down as i drive??

I have new crank thing. Also I have replaced all spark plugs and oxygen sensors. Replaced mass air flow sensors. it has to be something with air intake something small I'm thinking. Please help

The mechanic said that he couln't tell where the coolant leak was coming from. I need to add coolant about every two weeks (500-600 miles). I can't seem to see any noticeable coolant on the ground below the car. Mechanic advised that probably need a new radiator.

i have a 2006 bmw 525xi, and i it started making a noise a couple ofdays ago, it sounds like there is something trapped in the fan, and when i accelerate the noise gets louder. What is it? HElp! I took it an independent mechanic and he stated that it was the alternator, is that even true?
