Kadjar Cylinder Pressure Fluctuation

Hi, I've got a 2022 Renault Kadjar diesel with 234378 km. Recently, the check engine light came on, and I've noticed a drop in engine power and higher fuel consumption. I scanned the error codes and it indicates cylinder pressure fluctuation. I checked for obvious things like spark plugs but couldn't find anything. Any ideas?

A 2022 Renault Kadjar diesel experienced a check engine light, reduced engine power, and increased fuel consumption, with error codes indicating cylinder pressure fluctuation. Initial checks, such as inspecting spark plugs, did not reveal the issue. A similar case suggested a turbocharger problem, but a workshop diagnostic identified a faulty sensor as the cause. Replacing the sensor resolved the issue, restoring normal performance.

Did this summary help you solve your problem?

I had something similar on my Kadjar. Check engine light, performance drop... Sounded like engine knocking at times. Could be a consequential error.

Interesting. What was the root cause in your case? Did you experience similar mileage?

I did have similar mileage. Turned out to be turbocharger-related. I would take it to a workshop for a proper diagnostic.

Thanks for the tip! I did exactly that and they found a faulty sensor that was causing the pressure fluctuation. Replaced it, and everything's back to normal now. No charge! Appreciate the help!
