3. Uncover a jellied branch pipe of a fuel tank. Turn on a screw-driver (arrows on an accompanying illustration) small covers and turn away screws being under them. Remove two plastic facings.

4. Расстыкуйте штекерные connections of the gauge of oxygen. Расстыкуйте the tip of electromagnetic valve VANOS. Address to an accompanying illustration.

5. Remove штекерную a lath and take her aside.

6. Uncover at the inlet pipeline. Turn away a positive reference point (1) and compress two clips (arrows on an accompanying illustration). Disconnect a socle.

7. Remove a ventilation branch pipe in the top part of the block of cylinders. Address to an accompanying illustration.

Do not smoke. There is a danger of ignition! Wipe following fuel a rag. Disconnect at first the pipeline of giving (1) (from the filter), then the pipeline of return of fuel (2) at a distributive highway. For this purpose open collars. At assemblage it is necessary to replace collars.

At some models the giving pipeline is attached directly to a distributive highway. At assemblage it is necessary to replace a sealing ring on new and to grease with vaseline. There is a fastening of fuel hoses in the form of tightening скоб. In this case tool BMW is necessary for removal скоб 16 1 050. Before installation check up a sealing ring. In the presence of damages replace it, address to Section Removal and installation of injectors.

8. Disconnect a branch pipe throttle заслонки, address to Section Removal and installation of a branch pipe throttle заслонки.

11. Turn away bolts of fastening and remove a support of the inlet pipeline and a square of a hose of a cooling liquid of the inlet pipeline. Address to an accompanying illustration.

12. Расстыкуйте штекерное connection (1) at the valve of ventilation of a fuel tank. Take out the valve upward from the holder. Press a collar (2) and disconnect a hose. Расстыкуйте штекерное connection of the gauge of temperature of soaked up air and the valve of idling at the inlet pipeline. Address to an accompanying illustration.

13. Turn away bolts of fastening and remove the inlet pipeline from a head of cylinders.

Watch that any subjects have not got to inlet channels. It can lead to heavy damages of the engine.
