I have a BMW 325i with the n52 engine I'm getting a code for air mass metre signal 2d0f. when you start the car on a cold start and you press on the brake pedal the RPMs go up and down between 600 to 1000 rpm once the car is warmed up pressing the brake does not affect the rpm also the car doesn't want to start in temperature bellow -5 Which I assume is because of the the code

I have also replaced the MAF sensor and that did not solve the issue
and the engine does have an oil pan leak

any help would be appreciated
