Peugeot 208 Diesel Power Loss

I also own a 208 diesel and had similar symptoms. It does sound like it could be the intake manifold flap control. Have you checked if the engine light is on?

Yeah, the engine light is on. Did your engine light come on as well? Was it definitely the intake manifold flap?

Yes, the engine light was on, and after a diagnosis, the problem was indeed the intake manifold flap control. I recommend getting it checked by a professional, as it might cause further damage if left unattended. It cost me around 465€ to get it sorted.

Thanks a lot! I'll take it to a workshop. Hopefully, it's just the flap control. Appreciate you sharing your experience!
