Peugeot 5008 Engine Power Loss and Smoke

I have a 2016 Peugeot 5008 with a gasoline engine and a rather annoying problem. The check engine light keeps coming on, and I've noticed a definite reduction in engine power, especially when accelerating. Also, there's a bit of smoke when I put my foot down. The car has 267519 km on the clock. Any ideas? Could it be the crankcase ventilation valve?

I had a similar issue with my Peugeot 5008. Is the idle rough as well? Those symptoms do point towards a crankcase ventilation problem. It could be a defective PCV valve causing increased emissions and the smoke you're seeing. Have you checked for any vacuum leaks around the valve cover?

Rough idle sometimes, yes. Where exactly is the PCV valve located, and is it something I could check myself without special tools?

While some individuals with mechanical aptitude might consider a DIY approach, I would not advise that in this case. The crankcase ventilation system is crucial for emissions control and proper engine function. A malfunctioning valve can indeed lead to the symptoms you described. Given the mileage and the potential for further complications, I strongly suggest taking your Peugeot to a qualified workshop for diagnosis and repair to avoid any collateral damage and ensure optimum vehicle performance. If it indeed is the crankcase ventilation valve, expect a repair cost in the neighborhood of 360€ including labor and parts.

Thanks for the advice. I took it to the workshop, and you were spot on – crankcase ventilation valve was defective. They replaced it, and everything is running smoothly now. Appreciate the help!
