Hello, I am a Saab technician from upstate new york. It sounds to me that the turbo wastegate rod may be seized to the turbo control valve. The easiest way to try to fix this is to spray penetrating oil on the turbo valve/ wastegate rod and work it back and forth with a pry bar. Many times u can also heat this up with a torch and pray. If those two things don't work than the turbo valve itself is seized into the guide hole machined into the turbo. good luck.

Coincidentally i have the same car and i also had the same problem.There is a vacuum hose that runs from the PVC valve to a t-connector.One hose runs through the firewall and the other hose connects to the turbo valve.On my engine the hose was leaking and my turbo had zero boost.I replaced the leaking portion of the hose and my car is like a rocket now.

    Following up to my solution for TURBO NOT BOOSTING....the hose that goes through the firewall from the t-connector attaches to a nipple in the aquarium which is actually the back of the turbo boost gauge.

turbos that are not boosting may be loosing the pressure from cracked/split intercooler, loose hose clips, split hoses and seized up variable vanes in the turbine side which the actuator tries to work when it gets vacuum from the actuator control module. Check that this hose is not cracked or broken off

LC Prado 2LTurbo engine,turbo is not boosting.


check the piping from the compressor outlet to the throttlebody for boost leaks. also check to make sure that the wastegate actuator is functioning properly. it may be stuck open. the other thing to check for would be an exhaust leak either between the head and the exhaust manifold or the exhaust manifold and the turbo.
if its none of those things, check the blades on the turbo (compessor and turbine sides) for damage and make sure that it turns freely

Boost spiking/ over boosting


replace the wastegate vacum lines or wastegate acuator. if they leak it raises the boost. Let me know if its not that.
