Sprinter limp mode

[Cvietka]

Hello, i have limp mode on a sprinter, there's faults P24C600, P237600(boost pressure sensor Low-pressure turbocharger has a short circuit to ground.), P237528 (boost pressure sensor Low-pressure turbocharger malfunction. The signal offset is outside the permissible range), P226100 (wastegate has a mechanical malfuncition, but using star diagnostic it works well as i can see)

Do you have some ideas what to check and what to do?
Sprinter 2017 2.2
Big thanks.
