LandCruiser power loss and fuel consumption

I'm having some serious issues with my 2021 Toyota LandCruiser (gasoline engine). The check engine light is on, and the car feels like it's lost a ton of power. Engine response is terrible, almost like turbo lag all the time, and my fuel consumption has gone through the roof! It's got 182869 km on the clock. Anyone else experienced anything similar? I'm thinking it could be something with the intake manifold or maybe a pressure drop somewhere, but I'm no expert.

Sounds familiar. I had almost the exact same symptoms with my old Volvo XC60. Turned out to be a faulty boost controller. Have you checked for any fault codes?

Boost controller, huh? Interesting. Where is that thing located, and is it something I could potentially check myself, or am I better off taking it to a workshop? I am a bit of a novice when it comes to car repairs, to be honest.

On the Volvo, it was near the turbo. Honestly, unless you're comfortable working around the engine and have some diagnostic tools, I'd suggest getting it checked by a professional. Could save you a lot of hassle in the long run.

Thanks for the advice! Took it to the workshop, and you were spot on – turned out to be a defect in a vacuum switching valve. They replaced it for 140€, and now it's running like a dream again!
