t  Thrust piece -U-30042- Removing   Note In this process, the upper element of the intake manifold is removed and fitted along with the lower element.

–  Detach engine cover -arrows- (according to version).

–  Disconnect hoses -1-, -3- and -4-. –  Remove air duct by loosening hose clips -2- and -5-.

–  Separate the vacuum hose -arrow- to the brake servo on the intake manifold.

–  Unplug connector -1-. –  Pull hoses -2- and -3- off secondary air pump.   Note To release the tubes press hose connections together. –  Remove the dipstick together with the dipstick funnel and the bracket for the secondary air pump.

–  Unscrew the bolts on the bracket for the secondary intake manifold -arrows-.

–  Unscrew the bolts on the fuel rail and remove the expansion rivets from the fuel rail cable guide -arrows-.   Note The fuel line may remain connected on the fuel rail. –  Unscrew the remaining bolts -arrows- from the lower part of the intake manifold to the cylinder head.

–  Disconnect the electric plug connection -arrows- and clip the cable from the intake manifold. –  The solenoid 1 for the activated charcoal filter system -N80- and unclip the coolant hose at the intake manifold.

–  Pull off the connecter -1- and remove the throttle control unit -J338--arrows-.

–  Unscrew one bolt on the left and right respectively -arrow- at the rear attachment of the intake manifold.

–  Unscrew the remaining bolts -arrows- from the lower part of the intake manifold to the cylinder head. –  Next, open carefully the tabs on the upper element of the intake manifold (by pulling on the tabs to one side -arrows-) and remove the lower element by pulling forwards. During this operation, release the fuel distribution with the injectors from the lower element of the intake manifold.

–  Take fuel rail and injectors off intake manifold lower part as a pair -arrows- and lie on a clean cloth in the engine compartment.   Note Cover the intake conduits on the cylinder head with a clean cloth. Installing Installation is carried out in the reverse order of removal while noting the following:   Note Secure all hose connections with the correct hose clips (same as original equipment) → Parts catalogue –  Renew seals between intake manifold and cylinder head. –  Renew the O-rings between injector and intake manifold and lubricate with clean engine oil. –  Position fuel rail together with injectors (properly secured) against intake manifold and press into place evenly all round.
