Smooth, sluggish acceleration with hound dog noise following turbo gauge
On my 2002 9-5 Linear, auto tranny. This just started yesterday, after driving 3 hours. Now I'm 2.5 hours from home and not sure what's at risk with this rising howl that follows the turbo. It's not there at idle. The turbo gauge rises, but will not go into the yellow - max's out at the top of the green (lowest section). Next to no power. The engine is smooth and isn't missing. Could it be a vacuum leak, stuck bypass valve, or overboost protector? The car starts and runs fine otherwise. The sound does NOT follow engine RPM or tranny. Definitely seems to be linked to turbo RPM. I'm hoping it's safe to drive home. All ideas welcome. Thanks in advance for your thoughts.
