Charge air pipe

To remove


1. Remove the upper engine cover


2. Undo the bolt securing the bypass pipe to the turbocharger intake pipe.

3. Remove the bypass valve from the charge air pipe.

4. Unplug the connector for the pressure/temperature sensor on the charge air pipe.

5. Loosen the hose clamps on the throttle body and charge air hose.

Man: Detach the venturi hose from the charge air pipe


6. Undo the bolt securing the charge air pipe to the mounting on the cylinder head and remove the pipe. Cover the throttle body and charge air hose.

Important

If the charge air pipe is being replaced; first dismantle the pressure/temperature sensor. Then, fit it to the new charge air pipe. Apply petroleum jelly or the equivalent sparingly to the O-rings.



To fit


1. Remove the seal from the throttle body and delivery hose.

2. Carefully connect the charge air pipe to the throttle body and secure with the bolt on the mounting on the cylinder head.

Man: Connect the venturi hose to the charge air pipe.

Important

Check the O-ring on the throttle body, replace if necessary. In order to make fitting easier, the O-ring can be lubricated with a thin coat of petroleum jelly or the like part no. 30 06 665




Important

To reduce the risk of hoses mounted on the delivery side of the turbocharger coming loose due to low friction at high air pressures, the hoses and connecting pieces must be cleaned thoroughly before fitting. Use a rag dampened with 30 15 815 Cleaning agent to wipe clean inside the ends of the hoses. Clean also the connecting pieces. If hose clips are rusty or damaged, they must be replaced with new ones to maintain the correct clamping force.


3. Connect the charge air hose to the pipe. Tighten the hose clamp and the bolt on the cylinder head.

4. Plug in the pressure/temperature sensor connector.

5. Attach the bypass valve and tighten the bypass pipe to the turbocharger intake pipe.
