Removing

–  Lift engine cover panel at points -1- and pull it forwards in direction of -arrow-.

–  Detach spring-type clip from intake hose -arrow-.

–  Separate fuel supply line -1- and line to activated charcoal filter -2-. Press release tabs to do this.

–  Unscrew hose clip -1- at charge air pipe. –  Remove securing bolt for charge air pipe -2-. –  Remove front right wheel housing liner → General body repairs; Rep. gr.66. Remove poly V-belt → Chapter. –  Remove right drive shaft → Running gear, axles, steering; Rep. gr.40. –  Remove Lambda probe after catalytic converter -G130--1-.

–  Unbolt exhaust pipe from catalytic converter -arrows-.

–  Unbolt exhaust pipe to front silencer -arrows-.

–  Loosen securing bolts of clamp -arrows- and pull exhaust pipe to rear. –  Also pull out exhaust pipe together with flexible joint.

–  Push securing clip at charge air cooler in direction of -arrow- and pull hose -arrow- off.

–  Unscrew securing bolt for charge air pipe -arrow- and remove charge air pipe -1- downwards.

–  Opens clips for hose guides -2- and push hoses to one side. –  Carefully press locking lugs on noise insulation housing -arrows- outwards.

–  Pull off front housing with noise insulation.

–  Slacken supercharger poly V-belt by swinging tensioning element in direction of -arrow- with 16 mm open end spanner -T10241-. –  Lock tensioning element using locking pin -T10060 A-.

–  Unscrew securing bolts -arrows- for tensioning element and remove tensioning element. –  Hold supercharger shaft with 16 mm spanner -1-.

–  Remove securing bolt -2- for pulley and remove pulley and supercharger poly V-belt -3-.

–  Unscrew securing bolts -1- for supercharger and remove supercharger together with intake noise insulation. Removing noise insulation for charge air:

–  Pull noise insulation for charge air -2- together with pressure pipe in direction of -arrow-. Fitting   Note t  Renew O-rings on pressure pipe → Item. t  Before installing, lightly moisten O-rings with engine oil. t  The pressure pipe can only be pushed in one position into the intake silencer for charge air (note locating element).

–  Push noise insulation for charge air -2- together with pressure pipe in direction of -arrow- into intake connecting pipe. –  Press intake silencer for charge air -2- against crankcase to allow both dowel sleeves -3- to sit in holes.

–  Turn guide pins -T10341- hand-tight to stop in both lower threaded holes. –  Renew oil seal -1- and ensure it is correctly seated in the groove. –  Push supercharger together with intake silencer onto guide pins -T10341- and tighten upper securing bolts hand-tight. –  Remove guide pins -T10341-. –  Tighten lower securing bolts hand-tight. –  Tighten securing bolts -1- evenly in diagonal sequence.

Specified torque: 25 Nm –  Install supercharger belt pulley with poly V-belt positioned -3-.

Specified torque for new securing bolt -2-: 40 Nm + 1/4 turn (90°) further. –  Hold supercharger shaft with 16 mm spanner -1-. –  Install tensioner.

–  Tighten securing bolts -arrows- to 23 Nm.

–  Hold tensioning element using 16 mm open-end spanner -T10241- and pull out locking pin -T10060 A-. –  Position housing with noise insulation onto supercharger.   Note Ensure correct position of noise insulation in housing.

–  Press housing together with noise insulation against supercharger until locking lugs -arrows- click into place. Perform further installation in reverse order, paying attention to the following: t  Renew seals, gaskets and self-locking nuts. t  Hose connections and hoses for charge air system must be free of oil and grease before assembly. t  Secure all hose connections with the correct type of hose clips (same as original equipment). t  Install exhaust system and align it free of stress.

t  When installing air pipes with plug-in connector, ensure that securing clip -arrow- audibly engages into retaining lug -A-. Installing hose connections with connector couplings → Chapter. Tightening torques:   Caution The screw-type clips on the charge air pipes must be tightened to 5.5 Nm. If the torque is too low or too high, the charge air hose may slip off the charge air pipe during vehicle operation.
