Disconnect the ground wire on the battery with the ignition off. Remove the engine cover "arrows".
Remove the air duct "arrow".
Disconnect connector "1" from air flow meter "G70". Unscrew bolt "3" and release pressure sensor 1 EG "G450" "pos. 4" on the air duct pipe. Loosely lay connector "2" for EG temperature sensor 4 "G648" on the air duct. Remove the air duct hose with air flow meter "G70", for this loosen hose clamp "5" and open clamping clamps "arrows".
Disconnect vacuum line "1". Remove air filter housing and disconnect connector "2" on the rear side of air filter bypass flap valve "N₂75".
Unscrew bolts "2" and "3". Remove the air duct tube from the air duct hose by loosening the clamp "1" of the hose. Remove the right front wheel. Loosen the front part of the front right wheel arch liner and press it back.
Remove front noise insulation "1".
Unscrew bolt "1" and nut "3". Remove spacer "2" of the radiator frame on the right.
Cars with dual clutch transmission: Unscrew the bolt "arrow" of the ATF lines.
All
Disconnect connector "4" on the solenoid valve on the right for the electrohydraulic engine mount "N145". Remove fastening "5" of the electrical connectors from bracket "3". Unscrew nut "1" and remove the wiring harness bracket from the subframe. Cut cable tie "6" on the bracket and put the bracket with heat insulation aside. Unscrew nut "2" and remove the ground wire from the side member.
Disconnect the air duct hose from the air duct on the right and set it aside by loosening the clamp "arrow".
To loosen the poly V-belt, turn the tensioner clockwise "arrow", for this use the Torx T 60 "T40087" attachment. Remove the poly V-belt from the generator pulley.
Loosen the generator "arrow" bolts by about 6 turns. Carefully tap the bolt heads with a hammer to separate the generator mounting bushings. Loosen the bolts completely.
Remove the generator from the bracket. Remove the cover and unscrew the nut of the terminal 30/B+ "pos. 1". Disconnect the electrical plug connection "2".
Remove the generator "1" towards the right between the wire harness "2" and the ATF lines "3" "arrow", as shown in Fig.
Installation
Installation is carried out in the reverse order, in this case the movement of the alternator mounting bushings must be facilitated, since otherwise the clamping force of the bushing, despite the corresponding torque, is too low. To facilitate installation of the alternator, move the mounting bolt bushings slightly back. Vehicles with dual clutch: secure the ATF lines. Install the air duct tube on the right. Put the poly V-belt on the poly V-belt pulleys.
