1. Intake manifold
2. 9 Nm
3. Intake manifold flap valve -N316-
4. Vacuum intake manifold flap actuator
5. High pressure pump bolts: replacement; 1.8 l engine: 8 Nm + turn 90° (¼ vol.); 2.0 l engine: 20 Nm
6. Connector: fuel pressure regulator -N276-
7. Fuel pressure regulator -N276-
8. High pressure pump: with fuel pressure regulating valve -N276-; the fuel tank contains an electric fuel pump that supplies fuel to the mechanical fuel pump; when installing the high pressure pump, make sure that no impurities enter the fuel system; the high pressure pump must not be subjected to shock; to install a high pump in the fuel system there should be no excess pressure; relieve pressure in the fuel system; install fuel lines without stress
9. Roller follower: after removing the high pressure pump, it may remain in the vacuum pump, it is removed
10. Pressure fuel line; to the fuel rail of the FSI injectors; lubricate the spherical tips of the pressure fuel line with engine oil; lay the pressure fuel line without creating stresses (cleanliness)
11. Pressure fuel line: to the fuel rail of the MPI injectors; lay the pressure fuel line without creating stresses (cleanliness)
12. Union nut, 20 Nm: fuel pressure line
13. Fitting, 40 Nm: pressure fuel line; replace
14. Nozzles: replace O-rings and seals; pay attention to the correct installation position
15. Fuel rail for FSI injectors
16. Fuel pressure sender -G247-, 27 Nm: Lubricate thread with clean engine oil
17. Replace O-ring
18. Throttle valve control unit -J338-: with throttle valve actuator with electrical throttle module -G186-, throttle actuator angle position sender 1 -G187- and throttle valve actuator angle position sender 2 -G188-; Clean used throttle valve unit -J338- before installing; After removing and installing or replacing the throttle valve unit -J338-, it must be adapted again to the engine control unit -J623-
