Thanks. Yes, the idle is rougher. Can you share more about your issue? Were the symptoms the same?

Rough idle and smoke were key. It was a defective crankcase ventilation. Get it checked by a workshop to avoid bigger problems.

Thanks for confirming. I'll get the crankcase ventilation system inspected. Repair is about 360€.

I had a similar problem with my Prius, though I don't recall the year. The smoke and check engine light sound familiar. Any unusual idle or emissions changes?
