Where under the dash is the actuator for the defrost flap? I've got constant defrost (HEAT!!), as if the flap is stuck open, since it was used a couple weeks ago. Without a boost controller, air pressure is fed from the charge air (compressed side) of the turbocharger directly to the wastegate actuator via a vacuum hose. The inside of the wastegate is like the actuator attached to an internal gate, with a spring that holds the valve shut which is then overcome by boost pressure to allow the valve to open. A simple but careful rocking of the VGT actuator lever solved the problem. Its down on power and it seems like often the turbo does not kick in. The natural position is closed. Boost pressure (from the compressor) is applied at a diaphragm in the actuator so the waste gate opens when developed force overcomes the spring pre-load.

Turbocharged engines allow automotive designers the freedom to create vehicles that offer impressive power output ratios from more compact engines, enabling a reduction in weight and volume, as well as decreased fuel consumption, and cleaner exhaust gases. Over time the springs in some wastegates get softer. The throttle actuator is operated by the Engine Control Module (ECM) and it opens and closes the throttle valve using gears. It is also to reduce the back pressure in the exhaust manifold.


One of the functions of this valve is to relieve the pressure in the turbo, so as to keep seals from being blown. This can result in the valve being frozen open or closed, neither of which is good for the engine. Disconnect the actuator from the wastegate and see if the wastegate moves freely. the center vents don't work sometimes but they were like that before (that actuator seems to be a little weak on opening the flap). As boost pressure increases it forces the wastegate actuator to open and dump boost, so by reducing pressure to the actuator the wastegate control (WGC) solenoid increases boost when opened. If it were stuck shut you might notice more power from the engine (only if there is sufficient fuel flow) but higher exhaust gas temperature, possibly resulting in engine/turbo damage.
