t  Support equipment -T20174- Removing   Note To carry out this work it will be necessary to disconnect battery earth strap. For this purpose, first check whether a coded radio is fitted. Where necessary, check the anti-theft coding first. –  With the ignition switched off, disconnect battery earth strap.

–  Remove the sound proofing from the engine by pulling forcefully upwards -arrows- .

–  Remove the supercharger air tube -1- along with the connection tube -2- by separating the spring clips -arrows- .

–  Remove the air filter along with the air filter intake hose -6- . –  Separate the breather hose for the crankshaft sump -2- from the supercharger air pipe -5-.

–  Unscrew bolts -3- and -4- from the supercharger air duct -5-.

–  separate using the counterhold -T20174- the supercharger air tube flange -1- to the turbocharger. –  Separate the low pressure tubes from the pressure chamber and from the turbocharger. –  Extract the attachment nuts -2- from the front exhaust tube to the turbocharger. –  unscrew the coupling nut -3- from the oil supply lines.

–  Unscrew the turbocharger attachment bolts -4- .

–  Remove the central soundproofing → Bodywork, exterior installation work; Rep. gr.50. –  Remove the supercharger air pipe between the intercooler and the turbocharger → Chapter.
