Intake Air Plenum: Testing and Inspection

Testing the Intake Distributor (Leak Test)





Tools







1. Undo fastening screw M6 x 34 on the air cleaner housing.







2. Undo rear hose clamp between the air cleaner housing and intake manifold.







3. Tilt the complete air cleaner housing 90° to the left and remove to the rear.

4. Push rubber sleeve of special tool 9264/6 onto the plug.







5. Insert plug with rubber sleeve into the sealing bellows and fasten with the original hose clamp.







6. Generate a pressure of approx. 0.5 bar. Larger leaks are very easy to hear once the pressure has built up; smaller leaks can be made visible with a leak-locating spray.
