5. Disconnect the connector (1) and release the wire from the holder (2) Remove the bolt (4), loosen clamp (5) and remove the case (6) resonator assembly with air flow meter.
6. Release the wire (1) from the holder, give the nuts (2), disconnect the connector (3) and set aside the knot (4) fuel filter to the side.
7. Give nuts (1) and set aside the reservoir (2) power steering fluid to the side.
8. Remove the bolt (1) and set aside the cooler (2) fuel with air duct (3) to the side.
9. Give the nut (1) left engine mount. Remove the bolt (2).
10. Using a special lifting device, lift the engine by the lifting eyes by 25 mm.
11. Loosen clamps (1), remove the pressure hose (2) and disconnect the connector (3).
12. Loosen clamps (1) and put on the hose (2) to the return pipe of the turbocharger.
13. Remove hollow bolts (1) and remove pressure tube (2).
When installing, replace the o-rings on the hollow bolts.
14. Turn out bolts and remove assembly of a turbocharger forward.
