- 1 - Injector, always replace with combustion chamber sealing ring (teflon), replace O-rings, ensure correct installation position
- 2 - Support ring
- 3-Fuel ramp (Rail)
- 4 - Mechanical 1-piston high-pressure pump with fuel pressure regulating valve "N₂76". The fuel tank contains an electric fuel pump, which supplies fuel under a pressure of approx. 6 bar to the mechanical high-pressure pump. When installing the high-pressure fuel pump, it is necessary to prevent dirt from entering the fuel system. To install the high-pressure fuel pump, release the pressure in the fuel system, install the fuel line without tension
- 5 - Roller pusher
- 6 - Fuel pressure regulator "N₂76"
- 7 - High pressure pump bolts, replace, 10 Nm
- 8 - Fuel supply line nipple, replace, 22 Nm
- 9 - Fuel supply line union nut, 18 Nm
- 10 - Charge air regulating flaps
- 11 - Gasket, replace
- 12 - Intake manifold
- 13 - Vacuum reservoir for charge air regulating flaps
- 14 - Throttle valve module "J338", throttle valve drive "G186". Throttle valve drive angle sensor 1 "G187" and throttle valve drive angle sensor 2 "G188". After replacing the throttle valve module -J338, it must be re-adapted to the engine control unit "J623"
- 15 - Intake manifold bolts, tighten to 3 Nm initially and 9 Nm finally
- 16 - Intake manifold flap potentiometer "G336"
- 17 - Fuel pressure sensor "G247", 22 Nm, lubricate the threads with clean engine oil
