Removing . –  Remove the hose -1- from the vent on the crankshaft case. Press the unlocking buttons for this purpose. –  Leave the vacuum hoses open -arrows-. –  Remove air pipe from air filter housing; release hose clip -3- for this. –  Unscrew bolt -2-, swing air pipe with inlet connection to rear and pull off from turbocharger.

–  Unscrew bolts -arrows-. –  Release the hose clip -1- and remove the vibration damper -2-. –  Remove particulate filter → Chapter.

–  Unscrew bolts and remove pipes -A- for exhaust gas recirculation.

–  Unscrew bolts -1, 3-, union nut -2- and banjo bolts -4, 5-, and remove turbocharger support with oil supply line. –  Place drip tray for workshop hoist -VAS 6208- beneath engine.

–  Pinch off coolant hoses -1- and -3- with hose clamps -3094- and remove from exhaust gas recirculation cooler; loosen hose clamps for this. –  Unplug connector -2-. –  Remove vacuum hose -4- from vacuum unit and free. –  Unscrew bolts -arrows- and remove exhaust gas recirculation cooler. Fitting . l  Tightening torque → Chapter Installation is carried out in reverse order, noting the following:   Note t  Renew gaskets, seals and self-locking nuts. t  Hose connections and air pipes and hoses must be free of oil and grease before assembly. t  Secure all hose connections with the hose clips corresponding to original equipment → Electronic parts catalogue. t  Reinstall heat insulation sleeve in original position when installing. l  The sequence of the actions must be maintained so that a tension-free assembly of the combined flange (oil supply and oil return lines) is guaranteed together with the support of the exhaust gas turbocharger. l  This also guarantees the tension free assembly of the exhaust gas turbocharger supports between the cylinder block and the exhaust gas turbocharger at the same time. –  Fit the combined flange (oil supply and oil return lines) to the exhaust gas turbocharger and cylinder block together with the support of the exhaust gas turbocharger. –  Fit the oil return line to the exhaust gas turbocharger and cylinder block.

–  First bring the bolts -1- and the hollow bolt -4- of the exhaust gas turbocharger on the cylinder block by hand. –  Fix the screw -3- to the turbocharger. –  Then move the union nut-2- and the banjo bolt -5- for the oil supply line. –  Then insert the bolt -1- → Item, the banjo bolt -4- in the cylinder block → Item and tighten the support of the exhaust gas turbocharger -3- → Item one after another and in several stages to the specified tightening torque. –  Finally, tighten the screw of the clip of the oil supply line / support of the exhaust gas turbocharger. Tightening torques → Chapter

–  Install connecting pipes -A- for exhaust gas recirculation → Chapter. –  Installing support for turbocharger with oil supply line, inlet connection and impulse absorber → Chapter. –  Mount air intake hoses with screw clamps → Fig.. –  Install particulate filter → Chapter. –  Check oil level → Chapter. –  Check coolant level → Chapter.   Note After fitting the turbocharger, allow the engine to run at idle for about 1 minute, without accelerating; this will lubricate the turbocharger.
