BMW High Pressure Fuel Pressure Sensor - OE Supplier 13537537319

Replaced my busted one for this, no issues on car after year of driving

I had a sudden and complete fuel system failure at the track during a drift event in my 335i. Up to that point I had zero issues with the car and it was running perfectly at every event, an absolute ripper totally stock. At first we all assumed it was the High Pressure Fuel Pump, as that is the most common failure and the symptoms were very much like a total HPFP failure. Nevertheless, after way too much time spent learning, diagnosing and throwing parts at my N54’s fuel system I finally broke down and got an old Windows laptop on which I installed INPA and the other standard BMW tools to allow me to properly work on this thing. After breezing through the Germenglish menus and reading the live data it was obvious the High Pressure Fuel Sensor had failed and was reading a constant value. Over 25,000 kPa. Popped this new one in, fired it up, and the old N54 is back to perfect again. Some tips: - Get INPA installed and get an INPA compatible OBDII to usb cable if you don’t already have it. It’ll change your life. - If your Rail Pressure is reading a constant value (sometimes switching between two similar values), regardless of how high it’s reading, your high pressure fuel sensor has failed, buy this. - If your Rail Pressure fluctuates through the range under throttle load and engine stop, your high pressure fuel sensor works, don’t buy this. - Before removing the sensor from the back of the fuel rail BE SURE to either let the car starve itself of fuel and die, or pull one of your low pressure fuel pump fuses, start the car and let it die. This ensures the fuel rail depressurizes so it doesn’t spray fuel everywhere.
