Citroen C5 Loud Exhaust

I'm having some trouble with my 2013 Citroen C5 gasoline. It has 157138 km on the clock. I've noticed that my exhaust seems louder than usual, especially after a cold start when the engine sounds really noisy. I also get an error message stored in the error memory. After some research, I suspect it's the exhaust flaps not working correctly. Has anyone experienced something similar?

Hey! That sounds familiar. I had a similar issue with my old Opel Astra, though. Loud exhaust, especially on startup. I was going crazy trying to figure it out!

Interesting! What was the fix in your case? Was it definitely the exhaust flaps, and how much did it cost?

Yep, turned out to be the exhaust flap motor. I didn't try fixing it myself, though; I just took it to a shop and they sorted it out. From what I remember it was a pain to get to on the Astra; I’d recommend getting yours checked out professionally too.

Thanks for the advice! I took it to my local workshop, and you were spot on. The exhaust flap was defective. Cost me 190€ to get it sorted, which I’m not too happy about, but at least the car runs fine now!
