Are the cam shaft position sensors easy to replace, or will I be better off taking it to a mechanic? (considering I don't have too much practice working on BMW's)
I'm planning on changing my fuel filter very soon hopefully that helps. I have noticed that before I would turn the ignition on and wait until the beeping would stop and then start the x and it would fire up nicely. Recently however even if I wait before starting it starts up rough. This only happens during a cold start (usually the first start in the morning).
