Galaxy engine power loss

Hi, I've got a 2001 Ford Galaxy, diesel engine, with 244k km. Recently, I've noticed a serious drop in engine power. It runs really rough, and jerks quite a bit when accelerating. Plus, there's a loud hissing sound when I accelerate, and fuel consumption has definitely gone up. I suspect it might be something to do with the intake manifold flap control, maybe the switch is defective? Has anyone experienced anything similar? The engine light is also on.

Sounds familiar. I had something similar happen with my Galaxy. Any engine light? You mentioned jerking and hissing… almost like the engine is struggling to breathe properly. Does it feel like you're driving with the handbrake on?

Yeah, the engine light is on, forgot to mention that. It's definitely struggling. Feels like the airflow is completely messed up. Where was the problem with yours exactly?

Mine turned out to be the intake manifold flap control, precisely as you guessed. The mechanic said the switch was shot. Honestly, diagnosing it myself was a pain, so I just took it to a workshop.

Thanks a lot for confirming. I'll take it to a workshop then. Finally got the bill for 465€. They replaced the intake manifold control. Runs like new now.
