Is your plan to buy a "leak diagnosis pump" and replace it???? To get rid of that code?

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.

IMO
