Seat Arona EGR Issues

Anyone else having EGR issues with their Seat Arona? Mine's a 2018 diesel model with 115690 km. Lately, I've noticed reduced engine power, the check engine light is on, and there's smoke when I accelerate. It's also running rough and fuel consumption is up. Plus, a weird jerking and loud hissing during acceleration. I suspect the EGR valve is defective or jammed, affecting vehicle emissions.

Sounds like a bad EGR valve. I had similar symptoms on my Seat Arona, reduced power, check engine light, even some smoke when accelerating. It was a pain. Does it also have a rough idle? Could be a vacuum leak too, messing with the recirculation.

Rough idle sometimes, yes. How did you diagnose the EGR valve? Did you try cleaning it first, or just replace it?

I didn't bother cleaning it. The Arona is getting old, and I figured a replacement was the better long-term fix. The symptoms sound exactly like a worn EGR. Get it checked; a faulty EGR valve can cause more problems. Automotive repair is definitely needed.

You were right. The shop confirmed it was the EGR valve. Replacement cost 355€. It runs great now, no more rough idle or smoke. Thanks for the help.
