Hello! My name is John, I'm new here.
First of all, the car;
Saab 9-5
2.0t B205E
2001
225hp map
I am experiencing an issue where there is a very loud high-pitched whining/chirping/screeching noise when boosting above 0.5 bar of boost pressure.
It only occurs when driving, so, under load.
The sound was already present when I got the car. I have replaced the following parts;
Recirculating valve + hose
Boost Pressure Control Valve + hoses
All vacuum hoses
DI Cassette
I have also checked the intercooler hoses and intake pipe.
Does anyone have an idea? Thanks in advance.
