Answer
You'll need to know more about it before you can decide if it's something you can do or not.

I recommend taking it to a dealer, or a good independent BMW mechanic.  

Once they diagnosis it, you can decide.  You'll have to pay for their time and costs to do diagnostics, but then you can decide.
