) Position the vehicle on the ramp.DRAIN THE FUEL HIGH-PRESSURE SYSTEM AS DESCRIBED BELOW. Start up the engine.Maintain idle for 2 minutes.Remove the fuel pump relay.Wait for the engine to stall.Try to start the engine: if the engine starts within 10 seconds, wait for it to stall, then try to start it again; if the engine does not start withiin 10 seconds, continue cranking for a further 5 seconds. Wait until the engine cools down.Ensure that the ignition key is in the OFF position, then disconnect the negative battery terminal (-).

Proceed with removal - 4450B04 right front wheel r r . Proceed with removal - 7055B54 under-engine guard - r r . Proceed with removal - 1016A40 ignition coil cover on cylinder head- r+r . Proceed with removal - 1032B10 toothed timing belt - r + r for timing adjustment or replacement . Proceed with the removal - 1032B52 toothed driven pulley (one) - r + r (intake side and exhaust side) 1. Loosen the band and disconnect the vacuum pipe from the corrugated sleeve.2. Loosen the bands (2a) and remove the rigid pipe (2b) complete with corrugated air inlet hose (2c) from the air filter to the throttle casing.

1. Disconnect the rapid attachment for the fuel bypass pipe from the fuel manifold.

Collect the fuel which comes out.

2. Undo the connectors (2a), (2b) and remove the high-pressure pipe from the pressure pump to the single fuel manifold pipe (2c).

A new high-pressure pipe from the pressure pump to the single fuel manifold pipe must be fitted during reassembly.

1. Disconnect the rapid connector on the fuel supply pipe from the pressure pump.2. Undo the bolts (2a) and remove the pressure pump (2b) complete with O-ring (2c).

1. Undo bolts (1a) and move cam angle sensor (1b).2. Undo the bolts (2a) and remove the camshaft caps (2b).

The front cap has silicone sealant, so a plastic hammer should be used for its removal.

3. Remove the upper bearing shell for the front camshaft support, inlet side.4. Remove the camshafts (4a) and the front oil seals (4b).5. Remove the lower bearing shell for the front camshaft support, inlet side.

Refitting ( Removing

) 1. Place the inlet side camshaft front support lower bearing shell back in its housing. 2. Place the camshafts back in their housings.3. Place the inlet side camshaft front support upper bearing shell back in its housing.4. Place the camshaft caps (4a) back in their housings and secure them tightening the bolts (4b) to the recommended torque.

Apply silicone sealant between the front cap and the cylinder head.

2. Connect the rapid connector on the fuel supply pipe to the pressure pump.

1. Refit in its seating a new high-pressure pipe from the pressure pump to the single fuel manifold pipe (1a) and tighten the connectors (1b) and (1c) to the specified torque.

To ensure that the pipe is fluid-tight, first tighten the connector on the pressure pump side and then the connector on the fuel manifold pipe side.

2. Connect the rapid attachment for the fuel bypass pipe to the fuel manifold.

Place the rigid air supply pipe with corrugated air intake sleeve from the filter to the throttle body back in its housing and secure it using the bands.Connect the vacuum pipe to the corrugated hose and tighten the band. Proceed with the refitting - 1032B52 toothed driven pulley (one) - r + r (intake side and exhaust side). Proceed with refitting - 1032B10 toothed timing belt - r + r for timing adjustment or replacement . Proceed with refitting - 1016A40 ignition coil cover on cylinder head- r+r . Proceed with refitting - 7055B54 under-engine guard - r r . Proceed with refitting - 4450B04 right front wheel r r . Connect the negative (-) battery terminal.Remove the car from the ramps.
