My Saab 9-3 turbo wastegate seems to be stuck open. Pressure builds but will not kick on the turbo. Suggestions?
I think the actual problem may be generic to Saabs of the same age. So maybe this information will help many others
Yes the turbo was faulty but no it was simple to fix and did not cost me a lot.
the wastegate ( a valve which is opened to switch on the turbo) is driven by a vacuum actuator - and the actuator leaver arm which connects to the wastegate to the actuator had fallen off.
So The wastegate valve was stuck semi open up and never moved.
This does not directly show any engine error or cause any emissions
problems, as the car passed an a mot before immediately before the fault was found.
My local garage man did the work needed in 2.5 hours on the ramp and did not have to take much too bits to make a good repair.
Car goes like a train, and the engine management light - which was coming on at odd times has since stayed off.
I suspect that the management light which was coming on due to emissions sensors -- triggered by some series of events which cause the emmision to go out out of line, due to the turbo not fully working.
