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.

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?
