I had code 2722-Fuel Pressure Sensor elec diagnosis. The SES wouldn't go away despite clearing the codes with the Vishnu Procede. I went to BMW El Paso and bought a Low Pressure Fuel Sensor, Part #13537614317, $77. The directions above are great, but despite opening the gas cap there was a great deal of fuel spraying. I quickly unscrewed the old one and screwed in the new one. I cleared the codes and reset the ECU through the Procede Command Center. The SES is gone and everything appears good to go. I have 60,000 miles on my M3. This seems like a problem on post warranty vehicles. Thanks for the OP.
