2010 35d P0299

Hey I am trying to resolve this problem. I have a P0299 code that sets immediately after I try to clear it. It will set with the key on, engine off which seems kinda odd. Also after clearing the code it will immediately set again without ever starting the vehicle. How do I get a low boost fault without ever starting the engine? I was not getting low end performance at all and I pressured up the intake system and found a hose leak going into the intercooler and repaired that. I have good vacuum (29”) coming from the pump, the reservoir holds vacuum, I have good vacuum at the high pressure wastegate, and the turbo turns beautiful. I have also checked what I believe to be the low pressure turbo wastegate and it holds vacuum as well but it doesn’t have vacuum when at idle. I’m not sure where to go from here. I wish I knew what should and shouldn’t have vacuum at idle. Also, I just got this thing and it looks like the turbos and all the egr stuff is practically new. I’m a dealer so I don’t have a way to contact the previous owner and ask. I wish my scan tool would give me the MAP sensor values.
