olkswagen has been using an electronic diverter valve (DV) on their turbo TSI/FSI engines for a long time. Diverte valve is meant to release the pressure of the unused turbo power when you lift off the accelerator. It does two crucial things: seal pressure under boost to deliver peak power, and release pressure when you back off the throttle. In turbocharged VWs that are modified for performance, it also does something undesirable: It loses effectiveness, even failing..
The valve on your VW regulates the turbo power. When you are at an idle, the vacuum pressure opens the valve. The turbo boost is activated when the valve is fully closed. Lifting the throttle releases the boost pressure into the air cleaner box. If the valve is defective or inadequate, you will get a loss of boost, extended lag or a throttle response that is sluggish, the turbo charger will wear out soon as well. These problems go away with the installation of an aftermarket diverter valve..
