was driving and check engine light came on. Got code P0299. The lower pipe going in to the intercooler fell out. Fixed that. Still have the code. Message says most likely solution replace wastegate vacuum hose. I checked all vacuum hoses coming from turbo and found no leaks. Did a vacuum test on turbos and still holding pressure. Im lost.

 

There's a common issue with the boost pressure relief valve that sets P0299. O-Ring or gasket tears.

Checked blowoff valve already. Forgot to add that
