Limp mode no codes c220 om651 2012

hi everyone, first post on here so not sure if this is the right place.

C220 om651 2012
I recently replaced the intake manifold due to a sheared bolt and a code for a air leak, once replaced and cleared the car was still going into limp mode with a code for boost pressure too low. After chasing that for a week or two I finally found split hose and replaced. Took the car out for a test drive and it seemed to run fine. Took it out the next day and after the engine was up to temp limp mode kicked on again after hard acceleration. I have checked multiple times with icarsoft yet there seems to be no codes now. I’m honestly at a loss so any help would be appreciated!

P.S I have changed the majority of transducers and switchover valves

Have you reset air mass adaptions after sorting the air leaks?
