Yes, the idle is a little rough. Can you elaborate on the specifics of your issue? Did the diagnostic pinpoint the ventilation valve immediately, or did you have other codes initially?

The diagnostic pointed to emissions issues first, then narrowed it down to the crankcase ventilation valve. Honestly, after checking a few other things, I just took it to a trusted workshop to get it sorted. Best bet might be to get a quote from a garage to have it fixed.

Thanks for confirming. It seems the crankcase ventilation valve is the culprit, indeed. I've ordered the part, costing 360€, and will proceed with the replacement. Your experience was very helpful.

Sounds familiar. I have an Arkana too, though I am not sure of the build year off the top of my head. I had similar symptoms a while back – check engine light, sluggish performance, and a bit of smoke. It turned out to be the crankcase ventilation. Was idling rough, too. Is yours?
