Characteristic curve and setpoint values
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 BMW X3, 2016 BMW X3, 2015 BMW X3, 2014 BMW X3, and 2013 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.
The information on the rail pressure is transmitted to the engine control on a signal line. The effective signal for rail pressure fluctuates according to pressure levels. The measuring range of approx. 0.5 - 4.5 volts corresponds to a rail pressure of between 0 kPa (0 bar) and 25 MPa (250 bar).
