Overview of installation locations Parts A to J are not shown in the diagram. 1. Air mass meter -G70-; 2. Lambda probe -G39- with lambda probe heating element -Z19-; 3. Exhaust gas temperature sender 3 -G495-; 4. Connector for exhaust temperature sensor 3 -G495-; 5. Connector for lambda probe -G39-; 6. Exhaust pressure sensor 1 -G450-, adaptation must be carried out after replacement; 7. Coolant temperature sensor at radiator outlet -G83-; 8. Fuel temperature sender -G81-, installation location: in fuel pressure. highways; 9. Reducing valve, the task of the reducing valve is to maintain residual pressure in the return fuel. lines at 10 bar. This is necessary for normal operation of the injectors; the pressure relief valve may only be replaced as an assembly with return fuel lines; after replacement, it is necessary to let the engine idle for about 2 minutes to remove air from the power system; 10. Coolant temperature sensor -G62-; 11. Fuel pressure regulator -N276-, 80 Nm; 12. Intake manifold geometry adjustment motor -V183-, with intake manifold geometry adjustment flap position sensor -G513-; 13. Engine speed sender -G28-, 4.5 Nm; 14. Air flap/intake flap motor -V157-, with choke potentiometer -G69-; 15. Used engine -J623-; 16. Charge pressure sender -G31-, integrated with intake air temperature sender -G42-; 17. Exhaust gas recirculation radiator pump -V400-; 18. Exhaust gas recirculation valve -N18- with exhaust gas recirculation potentiometer -G212-; 19. Return fuel connector highways; 20. Injection pump with fuel metering valve -N290-, do not open the fuel metering valve -N290-; 21. Fuel pressure connector. highways; 22. Glow plugs; 23. Fuel pressure sender -G247-, 100 Nm; 24. Injectors; 25. Hall sensor -G40-; 26. Fuel return lines; fuel return lines cannot be disassembled; replacement is possible only when assembled with a pressure reducing valve; after replacement, it is necessary to let the engine idle for about 2 minutes to remove air from the fuel. system, then check the tightness of the return fuel. highways; 27. El. mag. Charge pressure control valve -N75-; 28. Exhaust gas recirculation radiator switch valve -N345-; 29. Connector for exhaust temperature sensor 1 -G235-; 30. Turbocharger guide vane position sender -G581-; 31. Air bypass valve. filter -N275-, parts (bypass valve with air bypass valve. filter -N275-) not installed in all equipment options; A. Relay and fuse block. in the switching block in the left drainage box; B. Low heating power relay -J359- and high heating power relay -J360-; C. Brake light switch -F- and brake pedal switch -F47-, in the footwell on the brake pedal; D. Clutch pedal position sender -G476-, only for vehicles with manual gearbox; E. Accelerator pedal position sender -G79- and accelerator pedal position sender 2 -G185-; F. Additional fuel. pump -V393-; G. Exhaust temperature sensor 1-G235-. Installation location: on the turbocharger, 45 Nm; N. Exhaust temperature sender 4 -G648-, 45 Nm; I. Connector for exhaust temperature sensor 4 -G648-; J. Particulate filter, installed on the bottom, after replacement it is necessary to adapt
After replacing exhaust pressure sensor 1 -G450- and/or the diesel particulate filter, an adaptation must be carried out. The adaptation is described in Guided Fault Finding or Guided Functions, use a tester. Installation location: Engine control unit -J623-. In mot. compartment in the left switch box.
Accelerator pedal position sender -G79- and accelerator pedal position sender 2 -G185-
The accelerator pedal position sender -G79- and accelerator position sender 2 -G185- are integrated into the accelerator pedal module and cannot be replaced separately.
Brake light switch -F- and brake pedal switch -F47- -1-
2. Clutch pedal position sender -G476-
Integrated components: clutch pedal switch for engine starting -F194- and clutch pedal switch -F36- (only for manual transmission)
Installation locations 1. Fuel pressure sender -G247-; 2. Fuel pressure regulator -N276-; 3. Intake manifold geometry adjustment motor -V183- with intake manifold geometry adjustment flap position sensor -G513-; 4. Choke motor -V157- with choke potentiometer -G69-; 5. Exhaust gas recirculation valve -N18- with exhaust gas recirculation potentiometer -G212-; 6. Fuel metering valve-M290-
