Default Audi A4 B5 1.8t Turbo problems!!!!

Ok so i noticed on my way back from myrtle beach to Cincinnati that i could hear my turbo spooling up for the first time, and i read on my boost gauge that i was pushing just over 5 psi. An amount of boost that i was never able to hit until then. The next day, i noticed that i was unable to push any boost. Basically my turbo was unable to create any power. So i pulled out the DV (diverter valve) and saw that it was shot. So i purchased a new 007 DV from forge Motorsports, installed it and my vacuum is working again, but still cannot my turbo to spool at all. I have checked all the vacuum hoses and hoses connecting to the turbos and they all seem to be fine. Not sure whats going on. Any help will be nice.

On mine the wastegate flapper got all loose and was never actually closing the waste gate. I had to replace the turbo.
