Troubleshooting Workflow: Towed to BMW of Vista Diagnosed as low fuel pressure sensor error estimated repair quote $950.00USD Repairs declined vehicle towed to a private garage BMW ISTA Diagnostics: See attached DOCs Fuel low-pressure sensor fitted (old) SENSATA pn: 13537614317 Workflow recommendation to change sensor to (new) BOSCH pn: 13537622231 Note: Changing from old to new due to fitment of the BOSCH housing a new and updated fuel rail is required pn:13537622850 (new with sensor) Old fuel rail with SENSATA sensor pn: 13538649966 FCP EURO retro fit kit without fuel rail upgrade SKU: KIT-13537622231KT Orderd one FCP EURO kit Installed retrofit kit. Cleared all codes with ISTA/D no stored faults Car test Driven for 3 mile loop Car passes test drive The vehicle is parked and left idle for 10 minutes after test drive Vehicle show fuel pump error (infotainment) and stall out. Retro fit kit removed and the sensor is replaced with a brand new SENSTA sensor old disregarding the upgrading of fuel rail. Car turns on and idles at 750rpm (normal) Car test Driven for 3 mile loop Car fails test drive goes into limp mode under hard acceleration in M mode limps last mile to garage The vehicle is parked restarted and error codes cleared with ISTA/D Vehicle show fuel pump error (infotainment) and stall out. Old Sensor left in place due to the nature of not replacing the fuel rail ordered 1 HPFP (vehicle has 2) New HPFP is installed Car test Driven for 3 mile loop Car passes test drive The vehicle is parked and left idle for 10 minutes after test drive Vehicle show fuel pump error (infotainment) and stall out.

FACT: Low Fuel Pressure sensor is part of a mechanical test routine and is not part of FAULT elimination via ISTA/D Theory: issue lies within EKPS module or low-pressure fuel pump location double gas tank under rear seats.
