P0299

[kosanow1]

My 2016 JGC started throwing the P0299 code (under boost). It's been doing this for a couple months. I can clear the codes and in a couple key cycles it will throw this code again. I've been trying a few things and haven't had much luck. Pressure checked and couldn't hear any leaks. New MAP and MASS sensor. New fuel filters. I heard that there may be a TSB on this. I was told it said, to check the O rings on the intercooler hoses and check the O2 sensors. I have looked for this TSB and can't find it. I'm thinking it may be more of a help section for the tech at the dealership. I've checked all the normal sites for TSB. Does anyone have any other sites that I could go and look at. Or does anyone have this TSB.

at dealership the DPF, MAP, EGR, Intake manifold and MASS were replaced to fix this. Luckily under warranty

I've done all of that except I didn't replace the manifold. I was thinking the pressure check would eliminate that. No DPF and EGR

I’ve heard of using a fogging agent can help locate leaks a lot easier because it give you a obvious visual location for the problem
