No boost?
My 2019 gls 450 isn’t making any boost. Just running on an all motor car. It’s very slow but drives without hesitation miss fire or any issue. It can get up to any speed just takes a bit. Someone would just think the car is very slow. There is no check engine light or stored code. I don’t know what this could be. Any thoughts?

I agree. However that is what is happening. Live data showing zero boost. Can get up to speed and drive around fine just takes time with zero boost. Running on motor only. When I scan it says no codes. I’m leaning toward boost sensor but I would think it would trigger a code.
