DS3 engine trouble

Yes, exactly! It's worse when the engine is cold. The check engine light is on pretty much constantly now. Is the EGR valve difficult to fix? What were your symptoms exactly?

Yep, sounds like the EGR valve. Mine was jammed open, causing all sorts of havoc. Reduced power, rough idle, emissions test failure... the works. I wouldn't try fixing it yourself unless you're experienced. Best bet is to take it to a workshop. They can diagnose it properly and replace the valve. Cost me about 350€.

Thanks for the advice! I took it to the workshop, and you were right – it was the EGR valve. They replaced it, and it cost me 355€. Runs like new now!

Sounds familiar! I had similar issues with my DS3. Does it feel like it's struggling, especially when cold? Check engine light is a pain. Does it happen all the time or only under certain conditions? It could be the EGR valve, but I'm no mechanic.
