Removing
  Caution
When doing any repair work, especially in the engine compartment, pay attention to the following due to the cramped conditions:
t  Route all the various lines (e.g. for fuel, hydraulics, activated charcoal filter system, coolant, refrigerant, brake fluid and vacuum) and electrical wiring in their original positions.
t  To avoid damage to lines, ensure sufficient clearance to all moving or hot components.
–  First check whether a coded radio is fitted. If so, obtain anti-theft coding.
–  With ignition switched off, disconnect earth strap from battery.
–  All cable ties which are opened or cut open when engine is removed must be replaced in the same position when engine is installed.
–  Remove engine cover.
–  Remove air cleaner → Chapter.
–  Remove intake hose and intake connecting flange between air mass meter and throttle valve module → Chapter.
–  Pull off connecting hose of crankcase breather between cylinder head cover and intake hose on cylinder head cover.
  Note
To do this, press down buttons on hose couplings.
–  Remove ignition coils with output stages using puller -T10095 A-.
  W00-0427
–  Unclip wiring harness of ignition coils out of cable guide -arrows-.
–  Unclip coolant hose -1-, breather line of activated charcoal filter system -2- and vacuum line -3- on intake manifold.
  N15-0476
–  Pull off 6-pin connector on throttle valve module -arrow-.
  WARNING
Steam may escape when expansion tank is opened. Wear protective glasses and clothing to avoid eye injuries and scalding. Cover cap with cloth and open carefully.
–  Open and close expansion tank cap to release pressure in cooling system.
–  Pull off coolant hoses from throttle valve module and seal hose ends.
  N15-0477
–  Unscrew earth connection from wiring harness bracket -arrow-.
  WARNING
Fuel system is under pressure! Wear protective glasses and gloves to avoid injuries and skin contact. Before opening the system place a cloth around the connection. Then release pressure by carefully loosening the connection.
  N15-0472
–  Pull off fuel supply line -1- (with white marking) and fuel return line -2- (with blue marking) off fuel rail and catch fuel that escapes in a cloth.
–  Seal lines so that fuel system is not contaminated by dirt.
  N24-1280
–  Unscrew cable guide for fuel lines, breather line of activated charcoal filter system and wiring harness on cylinder head cover -arrows-.
  N15-0473
–  Now pull vacuum lines -arrows- off intake manifold.
  Note
To do this, press down buttons on hose couplings.
–  Unclip pressure hose between combination valve and secondary air pump motor and all other lines from retainers on intake manifold and cylinder head cover.
–  Unscrew cable guide for coolant hoses and wiring harness on cover part → Item.
–  Pull vacuum hose off intake manifold changeover vacuum actuator.
–  Remove the two bolts on the side for the intake manifold support.
–  Pull connectors off thermal switch and radiator fan.
–  Remove front bumper: → General body repairs, exterior; Rep. Gr.63
–  Bring lock carrier into service position → General body repairs, exterior; Rep. Gr.50.
–  Unscrew dipstick guide tube from intake manifold.
–  Unscrew securing bolts of intake manifold and remove intake manifold together with throttle valve module.
–  Remove intake manifold and place it on a suitable surface so that the vacuum actuator will not be damaged.
  Note
Seal intake ports in intake manifold and in cylinder head with clean cloths.
–  Remove cylinder head cover.
Installing
Installation is carried out in the reverse order. When installing, note the following:
  Note
t  Replace cylinder head cover if damaged or leaking.
t  Bolt intake manifold first to cylinder head. Then tighten both bolts of intake manifold support.
t  Ensure that fuel hoses are tight.
–  If necessary fill with coolant → Chapter.
