Removal and installation of the inlet pipeline

The inlet pipeline needs to be removed, for example, at removal of a head of cylinders or the engine.

Model 316i, 318i (M43TU engine)

 REMOVAL

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

As a result of shutdown of the rechargeable 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 the Section Diagnostics of Malfunctions. Work it is desirable to carry out HUNDRED in conditions.

 REMOVAL

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

As a result of shutdown of the rechargeable 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 the Section Diagnostics of Malfunctions. Work it is desirable to carry out HUNDRED in conditions.

2 Remove a vozdukhosborny box, address the Section Removal and installation of a box of an air inlet.
3 Disconnect the gas drive at a branch pipe of a butterfly valve, address the Section Removal, installation and adjustment of the drive of a butterfly valve.
4 Remove an air hose between a box of the air filter and a branch pipe of a butterfly valve for what weaken a collar.
5 Rasstykuyte the socket of an injector of idling and the resonant gate at a branch pipe of a butterfly valve.
6 Turn off bolts of fastening and remove the cable mine under a branch pipe of a butterfly valve.

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

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

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

10 Uncover an oil filling mouth. Hook the 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 socket of the electromagnetic valve of the VANOS system.
