I would say take to a reputable MB independent near you. They would probably know problem from the fault codes. May need the facilities of a Star test to reveal all. If you post where you are located/based, I am sure members will come up with suitable recommendations for indie.

Post you location and someone will find you a local indy.

As a preliminary check all of the hoses to make sure there is no leaks on the boost side - very hard to see some splits

You could try changing the Map sensor ,as it's more than likely giving you all those codes , provided you've checked all air hoses for splits and are housed correctly.
