Default Code PO 244

The turbo is acting up again and still getting generic code PO244 wastegate solenoid range. Any one tell me if no vacuum applied to actuator does wastegate vanes divert exhaust gasses down exhaust pipe i.e. very little or no turbo boost and does max vacuum give most boost. I suspect maybe the wastegate vanes are siezing or intermittent action.

the vanes can stick due to a cracked control ring in the turbo , there are two of these rings which swivel the vanes , the rings are about 80 mm diameter ..

The vanes are almost closed with no vacuum , with max vacuum the vanes are fully open . All the exhaust gas goes through the variable nozzle vanes and spins the turbine and non of it is bypassed unlike the previous generation diesel turbos that used a wastegate .
