I had this issue as well. It would trigger a CEL in my situation P0299. I had a crack in one of the lines next to the pressure transducer. And I finally found it and replaced the U shaped connection.

It helped for a bit but boost was still inconsistent, after which I replaced the pressure transducer
(p/n - 010-153-13-28) boost switch that's connected to the turbo waste gates. This seems to have reawakened the car and it feels like it did the first day. This is the most recent part # for the transducer also.

I ordered this swapped it out and my car wouldn't boost at all! Did you have to do anything to reset the solenoid? Its crazy af because when i look up this part on MB it says "this part will not fit your car" buuut i literally see it on my car right next to the IC reservoir.
