Peugeot 2008 Check Engine Light Rough Running

I'm having a problem with my 2021 Peugeot 2008 diesel. The check engine light comes on, and an error is stored. The engine also runs a bit rough. Mileage is currently 112355 km. Suspect water sensor malfunction, likely due to a defective cable or plug connection.

That sounds familiar! I had a similar issue with my 2008 (also a diesel). Was your car showing any other unusual electrical behavior? Things like flickering lights or issues with the infotainment system?

No flickering lights or infotainment issues. Just the check engine light, error code, and rough running. Did you manage to fix it yourself?

I attempted to check the connections myself, but without proper diagnostic tools, I couldn't pinpoint the exact fault. Based on my experience and the symptoms you described, I’d recommend visiting a workshop to get it checked professionally.

Thanks for the advice. I went to the shop, and it was indeed a faulty connection on the water sensor. Repair cost was 95€. Problem solved.
