Charge Pipe Breaking on Turbocharged BMW

A common problem on turbocharged BMW models is the charge pipe on the intake side breaking.  This will cause “drivetrain malfunction”, “service engine soon” or “check engine” warnings to be displayed.  This fault is sometimes preceded by a large “pop!” noise, which is the pipe failing while under pressure.

Failure of this pipe will allow the pressure generated by the turbocharger to vent to the atmosphere instead of going into the engine.  This results in very low power, and unfiltered air being drawn into the engine.

If you experience this type of failure, a faulty charge pipe could be the culprit, and your BMW should be checked out immediately.
