Citroen C5 reduced engine power

I had a similar issue with my Citroen C5, although I am not sure of the build year. Check engine light, and the car felt like it was struggling to get power. Has your fuel efficiency also decreased? How's the air flow?

Yes, fuel efficiency has taken a hit and it feels as if the air flow is irregular. What was the problem, and what was the solution?

Sounds very similar to what I experienced. It was indeed a defective throttle body. I'd advise getting it checked at a workshop. Cost me around 265€ for replacement. A good workshop will make a diagnosis before doing the repair.

Thanks for the advice. I took it to a shop and you were right; it was a defective throttle valve which has now been replaced, at a cost of 265€. Appreciate the help!
