AMG GT Hybrid Engine Jerking and Hissing Noise

My 2022 Mercedes AMG GT Hybrid is acting up Check engine light is on and it's jerking like crazy when I accelerate I'm also hearing a weird whistling and a loud hissing noise when I give it gas Sometimes it even stalls when idling and my fuel consumption has definitely gone up Feels like the engine is losing power I ran a scan and it's showing a bad boost pressure sensor Could it be the cable or plug connection of the component I am trying to understand if it's something related to the turbo system or turbocharger or maybe even an air intake issue Any thoughts

Dude that sounds super familiar I had almost the EXACT same thing happen with my AMG GT Engine light the works My issue was a faulty pressure sensor too Turbo system was throwing codes all over the place Is the hissing noise getting worse

Yeah the hissing is getting louder especially when the turbocharger is supposed to kick in Where was your pressure sensor located Was it hard to get to I'm trying to avoid a huge repair bill

Man honestly I didn't even try to mess with it myself It was a pain just trying to diagnose it I took it straight to the workshop They replaced the pressure sensor and the problem was GONE Best advice Get it checked out by a pro

Thanks I appreciate the advice I took it to a workshop and you were spot on Turns out the cable for the pressure sensor was defective New sensor and labor cost me about 95€ Runs like new again
