DS4 Engine Smoke and Power Loss

Hi, my 2023 Citroen DS4 diesel has an issue. The check engine light is on, engine power is reduced, and there's smoke when I accelerate. Mileage is 101540 km. Any ideas?

Sounds like a PCV valve issue. I had something similar with my DS4. Is the smoke bluish, and does it smell a bit oily?

Yes, the smoke is bluish and smells oily. What did you do about it?

Yep, definitely sounds like the crankcase ventilation valve. Get it checked out at a workshop. Likely needs replacing, which should solve it. Don't keep driving like that!

Thanks, I appreciate the help. Took it to the workshop, and it was indeed the crankcase ventilation valve. Repair cost 360€, all fixed now.
