Charge Air Line Replacement – BMW B46/B48 Turbo 4 Cylinder Engine
Step 1 - Purchase Parts
Step 2 - Repair Procedure

The dish detergent acts like a lubricant and will in no way damage any of the parts!
- When installing a new charge air pipe, it is important to replace the sealing ring on the throttle body. Not replacing the sealing ring could cause a vacuum leak and error message(s).
- Make sure when reinstalling the charge air pipe to the turbocharger you audibly hear the locking clamp snap into place. If the pipe is loose or not connected correctly, you will get an error message and a rough running engine.
