Turbocharger System, Overview

Turbocharger System, Overview







1. EVAP canister
2. Vent line
3. Non-return valve
- For EVAP canister system
4. Turbocharger
The boost pressure regulator valve and vacuum diaphragm for boost pressure regulator valve are part of the exhaust turbocharger and cannot be replaced individually.
5. Combi-valve
For Secondary Air Injection (AIR) system
6. Fuel pressure regulator
7. To cylinder head cover
Crankcase ventilation
8. To brake booster
9. Suction jet pump
10. To vacuum reservoir
Two separate chambers
11. To Leak Detection Pump (LDP) V144
Only for engine codes AUG, AWM
12. Non-return valve
Bypass to suction jet pump
13. Non-return valve
For engine and vacuum control system
14. Crankcase ventilation
15. Secondary Air Injection (AIR) Solenoid Valve N112
16. Non-return valve
For EVAP canister system
17. Non-return valve
For Leak Detection Pump (LDP) V144
18. Charge Air Pressure Sensor G31
19. Air charge cooler
20. Throttle Valve Control Module J338
21. Intake manifold
22. Turbocharger Recirculating Valve N249
23. Vacuum diaphragm
For boost pressure regulator valve
Component of the turbocharger cannot be replaced
24. Wastegate Bypass Regulator Valve N75
Valve is activated (pulsed) by engine control module
Closed when no voltage present, limits charge pressure
25. Deceleration shutoff valve
26. Pressure regulator valve
For crankcase ventilation
27. Secondary Air Injection (AIR) Pump Motor V101
28. Evaporative Emission (EVAP) Canister Purge Regulator Valve N80
