Hello, my 2014 2.0 recently has had two issues pop up, first is I get a message on start up saying service brake assist. I have zero noticable driveability issues with the brakes and there is no warning light beyond that pop up message. The other issue is my car is under boosting, code P0229, first noticed this on the freeway when I went to pass someone and the car felt sluggish, took it to the auto shop who recently repaired my transmission thinking it was related but they scanned it and it showed the car wad under boosting. I haven't had the opportunity to get the car in for diagnosis, recently had some expensive work done and dreading having more, hoping someone might be able to shed some insight into possible causes to calm my $$$ fears. The car feels totally normal at lower speed still pulls quite hard but on the freeway is when I notice it, I dont thrash my car so unsure if I floored it at low speeds how it would respond. My car has 170k or so miles on it, I haven't noticed any roughness with the engine or fuel economy issues either.
