11 - Combination valve for secondary air injection (AIR)
12 - Check-valve for EVAP canister
^ Installation position: Arrow on valve points in direction of flow, as shown in illustration.
13 - To brake booster
14 - Vacuum suction jet pump
15 - Check-valve
^ Installation position: Arrow on valve points in direction of flow, as shown in illustration.
16 - Crankshaft housing ventilation
17 - Vacuum reservoir
^ Component location: Under wheel housing liner in front left wheel housing
18 - Check-valve
^ Installation position: Arrow on valve points in direction of flow, as shown in illustration.
19 - to Leak detection pump (LDP) -V144-
20 - Check-valve
^ Installation position: Arrow on valve points in direction of flow, as shown in illustration.
21 - Secondary Air Injection (AIR) Solenoid Valve -N112-
^ Component location: Below intake manifold
22 - Charge air cooler
^ with Charge Air Pressure Sensor -G31-
23 - Recirculating valve for turbocharger - N249-
^ Component location: Below intake manifold
24 - Vacuum diaphragm for boost pressure regulation
^ When the combination valve is opened, the mechanical boost pressure regulation valve in the turbocharger is opened and secondary air is thereby channeled past the turbocharger directly to the catalytic converter
