Hello has anyone dealt with a turbo underboost code 2359-001 check system charge pressure control ? I have 2008 E320 bluetec. Itll run normal for few minutes than ill get major power loss with no throttle response. Will not go over 40 mph. Could it be an actuator problem?

Perhaps the exhaust back pressure sensor? https://www.justanswer.com/mercedes/939g6-2008-ml-320-cdi-just-bought.html
Check intercooler piping thoroughly. Here's a case where the intercooler itself was the culprit: 2359-001 Code Solved with Doktor A Advice Again

Well no auto parts store has that sensor, i took it out and cleaned it. Still has the same problem. Ill have to order it new and it see if it works.
Check all turbo hoses for damage (splits may be difficult to find), intercooler head has no cracks, Your EGR and swirl flaps are ok. After start, before car goes to limp (engine revs over 3000), see if turbo arm is moving when someone revs it up. Soldering inside turbo actuator are prone to fail, but any boost related codes can be triggered any leak around the air path from turbo to engine.
