Just a note on the P0172 code link. '02-'06 MINIs do not have a mass airflow (MAF) sensor. They have two MAP sensors that work together to determine the proper air/fuel mixture. This is also known as speed density.
You have an aftermarket header and aftermarket exhaust. Look to see if you have an exhaust leak. This can cause false codes with the O2 sensors. Definitely check for vacuum leaks around the engine as well. Get a piece of hose and hold one end to your ear. Listen for a distinct hissing sound.
Another thought that comes to mind is you could possibly have a problem with your high-pressure fuel pump. Testing will require a mechanic's diagnostic.
