99.5 1.8TQ
Autothority Stage II software
Stock turbo.
Borla Exhaust.

Car will show boost of .1 bar whereas it used to peak @ .9 and hold at about .7. Obviously something is seriously wrong. This is my first turbo issue and I've heard informed diagnoses ranging from limp mode to broken BPV to boost leak to stuck/broken wastegate to complete turbo failure. I can hear air "blowing" when the pedal is depressed far enough down to normally make the turbo spool but not the high pitched whine of it actually spooling. ANY ideas, things to check out, ANYTHING, would help me immensely!

Thanks!!!<ul><li><a href="http://www.modifiedrecordings.com">Modified Recordings - Official Soundtrack of Mischief 3000</a></li></ul>

Something may have popped off, check all your intercooler hoses...BPV...and vac lines...

For your intercooler hoses, especially the 90degree ones you may have to take them off to examine for a crack...one of mine had a 1 inch crack one time...

Check all hoses
