Have you experienced any fuel pump issues with your N54? I didn't do a ton of research on the issue before bought, and am not so much worried as curious. My understanding is the thing is warrantied for 10 years against failure now. I have done a lot of searching online, and cannot seem to get a straight answer as to if the replacement pumps actually fix the problem or if it is a bandaid solution. I called the BMW dealer and it is an open recall on mine.
