The exhaust module, consisting of the exhaust manifold and exhaust turbocharger, needs to be removed and installed as a single unit. Start by disconnecting the negative battery cable and removing the engine cover. Remove the strut tower crossbrace, sound insulator, and lower splash shield. Drain the engine oil and coolant. Remove the heat shield, disconnect the exhaust system from the turbocharger, and disconnect the right side pipe of the charge air cooler. Disconnect the vacuum line to the wastegate and the electrical connector to the blow-off valve. Remove the wastegate linkage wire retaining clip and disconnect the linkage. Remove the vacuum unit and the harness routing brackets. Remove the turbocharger support bracket and the oil return pipe. Remove the mounting nut and the oil return line bolt. Separate the coolant lines and remove the oil feed line bolt. Finally, remove the exhaust module mounting nuts in a circular pattern and remove the assembly. When installing, replace the graphite seal on the cylinder head and ensure the assembly sits flush before tightening the mounting nuts.
