Unlock catch -arrow- and detach vacuum hose -1-. Detach vacuum hose from mounts on air duct -2-. Release the air hoses from the mountings on the charge air pipe.
Disconnect connector -1 -. Unfasten retainers -arrows- and remove charge air pipe.
Remove screw -1-, loosen clamp -2-. Disconnect coolant hose. Disconnect the other two coolant hoses from the coolant connection in the same way.
Disconnect electrical connectors.
1. Canister solenoid valve 1 -N80-
3. Throttle valve unit -J338-
4. Intake manifold pressure sender -G71-
Remove bolt -arrow-. Press release buttons and disconnect canister hose -2-. Unclip fuel line -5- and coolant line -6- from retainers on intake manifold and move to one side. Unplug connector -1- for fuel pressure sender -G247-. Disconnect the connector from the oil pressure sensor as well.
