XC40 EGR valve issue

I own a 2018 Volvo XC40 with a diesel engine. Recently, I've noticed reduced engine power, the check engine light is on, smoke when accelerating, rough engine running, higher fuel consumption, jerking, and a loud hissing sound during acceleration. Mileage is 111466 km. Could this be related to the EGR valve?

Sounds familiar. I had a similar set of symptoms on my BMW 3 Series diesel. Check engine light, rough running, the works. It turned out to be a jammed EGR valve. Have you checked for any error codes? That's usually the first step.

Thanks for the insight. Where exactly did you find the error code, and is there a way to check the valve yourself?

I used an OBD2 scanner to pull the code; many auto parts stores will scan it for free. You could try cleaning the EGR valve yourself, there are some tutorials online, but honestly, it's a messy job and if it's truly defective, cleaning won't fix it. It's probably best to take it to a workshop.

Appreciate the advice. I took it to a local workshop, and indeed, the EGR valve was defective. The repair cost 355€. Thanks again!
