4530 Regulacja ciśnienia doładowania, poziom wysokiego ciśnienia, uchyb regulacji: Ciśnienie doładowania za niskie / dodatni uchyb regulacji
Observe cross-effect with charging pressure control. Problems with the exhaust-gas recirculation can affect the charging pressure control and vice versa.
If the hot film air mass meter is replaced, the following service function must be carried out: Delete adaptations, air mass system.
If the exhaust-gas recirculation valve is being renewed, the following service function must be carried out: Delete adaptations, air mass system.
If the swirl flaps are replaced, the following service function must be carried out: Delete adaptations, air mass system.
If leaks were found in the air mass system, the following service function must be carried out: Delete adaptations, air mass system.
4501DDE: Regulacja recyrkulacji spalin, uchyb regulacji
Service Plan
Check the following possible fault causes:
1. Leaks in the air mass system downstream of the compressor.
2. Severe sooting in the exhaust-gas recirculation cooler.
3. Leaks in exhaust emission system before turbine (e.g. broken bypass pipe of the exhaust-gas recirculation cooler).
4. Throttle valve faulty (in conjunction with faults on the throttle valve).
5. Exhaust-gas recirculation valve faulty (in conjunction with faults in the exhaust-gas recirculation valve).
6. Exhaust turbocharger (in conjunction with faults in the exhaust turbocharger).

M57 P0402 4507 DDE: Regulacja recyrkulacji spalin, uchyb regulacji
Service Plan
Check the following possible fault causes:
1. Leakage in air mass system between hot film air mass meter and compressor.
2. Exhaust-gas recirculation valve faulty, jams open (in conjunction with faults on the exhaust-gas recirculation valve, in particular position rule deviation and detection of a jamming).
3. Hot film air mass meter faulty.
4. Swirl flaps jam closed (in conjunction with faults relating to the swirl flap).
5. Intake valves carbonised.
6. Throttle valve faulty (in conjunction with faults on the throttle valve).
7. Dirty air filter.
8. Exhaust turbocharger faulty (in conjunction with faults in the exhaust turbocharger).

rozwiązaniem była wymiana pompy w zbiorniku, pompy progowej jako takiej nie ma, cały mechanizm znajduje się w zbiorniku. Wyczyszczony zbiornik , wymiana pompy + filtry zakończyły wszystkie problemy. Pozdrawiam
