Models 320i, 323i, 328i (M52TU engine)

 REMOVAL

1 Disconnect a negative cable (-) the storage battery at the switched-off ignition. The battery is in a luggage compartment behind a cover on the right side. At BMW 316i, 318i cars the battery settles down in an impellent compartment.

As a result of shutdown of the storage battery data from memory of malfunctions of some monitors are erased. If necessary, before shutdown of the battery it is necessary to consider these memories of malfunctions. Address to the Section Diagnostics of malfunctions. Work it is desirable to lead HUNDRED in conditions.

2 Remove an airmodular box, address to the Section Removal and installation of a box of an air inlet.
3 Disconnect a gas drive at a butterfly valve branch pipe, address to the Section Removal, installation and adjustment of a drive of a butterfly valve.
4 Remove an air hose between a box of the air filter and a butterfly valve branch pipe for what weaken a collar.
5 Rasstykuytes I will corrode an injector of idling and a resonant zaslonka at a butterfly valve branch pipe.
6 Unscrew bolts of fastening and remove cable mine under a butterfly valve branch pipe.

7 Disconnect a hose oil plum at a directing pipe of the index of level of oil, previously having weakened collar fastening.

8 Unscrew directing pipe of the index of level of oil at the inlet pipeline.

9 Unscrew fastening bolts (arrows on an illustration) and remove a butterfly valve branch pipe together with consolidation.

10 Uncover mouths of filling of oil. Hook a screw-driver small covers (arrows on an illustration) and remove. Weaken the bolts lying under them. Remove 2 plastic facings.

11 Take out shtekerny connections of sensors of oxygen (an arrow on an illustration). Rasstykuyte I will corrode the electromagnetic valve of VANOS system.

12 Lift and take aside a shtekerny level of injectors.
