Seat Ateca Engine Issue

I'm experiencing a potential malfunction with my 2023 Seat Ateca gasoline engine, currently at 62034 km. The check engine light is illuminated, and I've observed reduced engine power accompanied by smoke during acceleration. Could this be related to a defective crankcase ventilation valve? I suspect the PCV valve is faulty, impacting emissions. Is this a common issue, requiring immediate maintenance?

Reduced engine power and smoke? Sounds familiar. I had something similar with my Ateca, though I can't recall the exact symptoms. Was the check engine light on constantly?

The check engine light is indeed on constantly. Did you also experience issues with emissions or notice any specific noises? Was it also the PCV valve in your case?

Yes, constant check engine light. And yes, it was indeed the ventilation, or PCV valve. If you're seeing smoke, I'd say it's pretty much confirmed. Get it checked ASAP, you don't want to mess with emissions controls. Off to the workshop with it!

Thank you for confirming this. I have taken it to a workshop, and the crankcase ventilation valve was indeed defective. The repair cost was 360€. Hopefully, this resolves the issue permanently.
