The common rail system in the 1.5 dCi relies on tightly regulated fuel pressures—ranging from roughly 230 bar at idle up to over 1600 bar under high engine load. The ECU continuously reads data from the fuel rail pressure sensor and uses an Inlet Metering Valve (IMV) / fuel pressure regulator on the High-Pressure (HP) pump to adjust flow. If the pressure swings outside the safe, pre-programmed thresholds, the to protect fuel system components from damage.
