Welcome to Bimmerfest!

I moved your posting to the E83 forum (X3, 2004-2010) so you can get model-specific help.

1) Clean the MAF, and replace the air filter (if neither are new)

2) Get a BMW-specific code reader such as the Creator C310; there's plenty of double-secret codes.

3) Do a smoke-test to look for vacuum leaks. I hear a very common one on M54s is a cracked intake boot, so if you are very-able you may proactively want to remove, clean, and inspect it carefully for cracks.

Others with M54s will hopefully give you more ideas.

P.S. Soon, make a signature file, for your future posts, with basic info about your X3. See below for an example.

Very first thing I'd look at is the rubber bellows in the air intake; M54 is notorious for them. Both banks lean supports that idea. Valve cover gasket is another vacuum leak source. It doesn't seem to be misfiring so you can eliminate misfires as a lean source.

90% sure you have a vacuum leak somewhere. I purchased a 2004 X3 3.0L last year and had the same codes. There are multiple places that your motor can leak from. I'm going to tell you what I did. I replaced all soft parts on the top end: valve cover gasket + grommets, intake boot, entire CCV system, dip stick tube o-ring, dip stick o-rings, DISA valve rebuild + gasket, throttle body gasket, intake manifold gasket, FI gaskets, vacuum lines, vacuum plugs, other parts I'm sure I'm forgetting. I did a bunch of other work while I was in there, but that's what I did to address the vacuum leak.

Get a scanner. You can get OBD Fusion for $10 for your phone and a $20 LE BT adapter - that's all you'll need for this job. There is a ridiculous amount of information out there on how to fix P0171 & P0174. Spend some time searching and you'll find everything you need.

I've gotten that code at least three times on my 2005 (200k). First two times - cleaned MAF and it went away. Last time (6 month ago) - needed to replace CCV valve. At the time I was also getting the occasional huge plume of smoke at start up, occasional erratic idle.
