I took my car to fremont bmw and took a look at the underside. The mechanic said there is a rear differential leak and need to take it apart and replace the parts etc... here is the pic I saw under the car.

the parts and labor is like $1300. I am not seeing any leak where I park my car. but it is definitely showing a leak there.

any advice?
