There is a leak in the turbo piping system, intercooler or waste gate control valve. These are all common places for this noise to be caused by. Intercooler leaks are hard to locate due to the core cracking and the hole being very fine.

Where do I find the Waste Gate Control Valve, is it electronic or mechanicle, and is it adjustable or do I have to replace the valve? Thanks
AU Auto Mechanic: Curtis, Australia Car Mechanic replied 8 years ago
The waste gate control valve is located on the side of the turbo. The valve is mechanical. It may need replacing but you won't know unless you have it tested.
