BMW part number 16126754016 (16-12-6-754-016) or Mahle KL167 is the fuel filter for BMW (and Range Rover) high-end sport utility models from the 2002 to 2006. The pressure regulator is entirely integrated inside the metal canister shell. It features a 4-port design (two inlet pipes and two outlet pipes) to manage the fuel filtration, pressure regulation, and excess fuel return loops all within the single unit. Because the regulator is non-removable, the entire assembly must be replaced if the internal regulator mechanism fails or gets clogged. Most premium specialist suppliers recommend a total assembly refresh roughly every 36,000 to 60,000 miles to prevent lean fuel condition fault codes or premature fuel pump wear. (gar2-Y2)
