Bipper engine check light and power loss

My 2013 Peugeot Bipper diesel, with almost 300k km, has the check engine light on and a loss of power, especially when accelerating. Plus, there's some smoke. Could it be the crankcase ventilation valve?

I had similar symptoms with my Bipper. It sounds like your PCV valve might be the culprit. Have you checked for any oil leaks around the valve or the emissions?

I haven't specifically checked for leaks around the valve, but I did notice some oil residue near the air filter. Is that related, or could it be something else?

Oil residue near the air filter could indicate a PCV valve issue. A defective crankcase ventilation can cause pressure to build up, leading to leaks and other problems. I would suggest a visit to the workshop.

I took it to the workshop, and you were right, it was indeed the crankcase ventilation valve. Cost me 360€ to get it sorted, but at least the smoke is gone, and the engine runs smoothly again.
