If I were faced with that code I would google the code, with "BMW" and read all I could...THEN I would come to understand that there are several things that can cause the DME to think it has a bad pump. ONE is a bad pump. Others are bad gas tank caps, and DTML solenoids...could be others.
Codes are not 'replace this part' instructions.... it just tells you were to start the diagnostics.

I have done a TON of reading on this from every Bimmer forum to the actual BMW service/repair manuals and the "common" cause is the pump itself.
My plan was to remove the pump and get power to it as a minimum to see if it's running.
I have already replaced the gas cap since it was cheap and easy.
Finally, I don't have the troubleshooting expertise but replacing a $70 pump as a shot at fixing it is a hell of a lot better than paying a mechanic at either the dealer or an Indy over $100 an hour in labor. I trust auto mechanics about as much as I trust....well...noone. I dont trust them. I've seen them bill people over and over again several hours on BS like front brake pad changes.
So long story short, I agree with you that I do my homework, make an educated guess and then start with the most probable and least expensive replacement options.
