My R55S displayed all symptoms of failing HPFP..Set point value of 0.00 bars. Installed a new aftermarket pump, same reading. Installed two more..remans this time...same symptoms and set point value of 0.00 bar. I've replaced every sensor there is with new oem, but still have the problem. Any thoughts or suggestions will be greatly appreaciated. Is there a way to adjust the set point pressures?

 

did you check the fuel rail pressure sensor?

 

Yes I did, and pressure is in spec as I recall. I'll do a recheck tomorrow to be sure.... the regulator is new.

 

The pressures are as follows:
Actual rail pressure: 0.87 Kpa
Rail pressure Set Point: 0.00 Kpa
Adapter value: 0.97 Kpa
Duty Factor fuel control value: 0.00 Kpa

And these are the codes currently displayed:

27CF Not Present, Fuel Supply System
27CE Fuel Supply System
28EE Fuel Pressure Plausibility
2880 High Pressure System
2F07 Present, Map Tstat Mechanism

MAF, MAP, Thermostat, Fuel pressure & Temp sensors are all new OEM

 

Mini had a service bulletin on this, check with your dealer

 

..but we installed a new aftermarket, then two OE rebuilt pumps yet the pressure readings/fault codes are the same.

 

did you ever get to the bottom of this mine is the same.
