 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 cars BMW 316i, 318i the battery settles down in an impellent compartment.

As a result of switching-off of the storage battery the data from memory of malfunctions of some monitors is erased. If necessary, before battery switching-off it is necessary to consider the given memories of malfunctions. Address to Section Diagnostics of malfunctions. Work it is desirable to spend HUNDRED in conditions.

2 Remove воздухосборную a box, address to Section Removal and installation of a box of an air inlet.
3 Disconnect a drive of gas at a branch pipe throttle заслонки, address to Section Removal, installation and adjustment of a drive throttle заслонки.
4 Remove an air hose between a box of the air filter and a branch pipe throttle заслонки, for what ослабьте a collar.
5 Rasstykujte a socket of an injector of idling and resonant заслонки at a branch pipe throttle заслонки.
6 Turn away bolts of fastening and remove cable mine under a branch pipe throttle заслонки.

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

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

9 Turn away fastening bolts (arrows on an illustration) and remove a branch pipe throttle заслонки together with consolidation.
