Focus diesel EGR valve issue

I've got a 2011 Ford Focus diesel with some issues. Engine power is down, check engine light is on, and it's smoking and running rough when I accelerate. Fuel consumption is up, and it's jerking with a hissing sound during acceleration. Could it be the EGR valve?

I also drive a Focus with a diesel engine. Have you considered the catalytic converter? I had similar symptoms a while back. Have you checked for any vacuum leaks?

Thanks for the tips! I haven't checked the catalytic converter or vacuum leaks yet. If it was a faulty EGR, how did you figure it out?

I didn't have smoke when accelerating, so it might be something else. My rough idle went away after replacing the EGR valve. I'd recommend taking it to a workshop.

Just wanted to let you know it was the EGR valve! A mechanic confirmed it was defective and jammed. The repair cost 355€ including parts and labor. Thanks for the help diagnosing it!
