W211 on highway went into limp mode

Hey, my W211 FL 300CDI suddenly went in limp mode and turbo doesn't give any boost when driving above 90 km/h.
Code reader shows this fault code - P2359 - boost pressure too low

Anyone have experienced this problem before and have successfully fixed it?

I am guessing it is a hose leak. Cause I was on motorway and everything was fine. Took over few cars and pushed gas pedal harder and probably some kind of hose cracked from sudden high boost. After the hard push.. it went into limp mode

Thanks!

It happened to me on a 2004 E320 CDI
The EGR Valve was hung up with carbon.
Dealer removed cleaned and it's been OK since. I'm expecting it to happen again.
