¹Measured at the fuel supply line in the engine compartment after the ignition is turned on and then turned off when the pressure stops increasing. If the pressure is exceeded, and the return line between the filter and the pump is not clogged, the fuel filter should be replaced, since the pressure limiting valve is faulty. If the pressure is insufficient, if the pressure before the filter reaches 6-7 bar, replace the filter; otherwise replace the pump.
² If the pressure continues to decrease and the tube leading to the high-pressure fuel pump is sealed, replace the high-pressure fuel pump.
³Measured at the fuel supply line in the engine compartment with the engine running. If the pressure is insufficient or unstable, replace the fuel pump.
4 Measured at a fuel temperature of 15-30°C.
