A 2022 Renault Arkana hybrid with 210,689 km is experiencing engine stalling at idle, a check engine light, and reduced power. The suspected cause is a defective fuel volume regulator, potentially linked to a failing high-pressure fuel pump. A similar issue was resolved by replacing the defective pump, which was confirmed by a repair shop inspection.

Thanks for the response, I appreciate the insight. I haven't done a precise calculation regarding fuel efficiency, but it does seem to have decreased somewhat. Could you tell me more about your experience with this issue?

The decreased fuel efficiency combined with the other symptoms strongly suggests a fuel regulator issue, potentially a failing high-pressure fuel pump. The workshop confirmed the pump was defective in my case. I would advise getting yours checked ASAP.

I appreciate the information. I took the vehicle to a certified repair shop, and their inspection indicated that the high pressure fuel pump was defective, requiring replacement of the fuel volume regulator. The total cost was 1510€. Thanks again for your help.

I have an Arkana as well and experienced similar symptoms a while back. The check engine light, rough idling, and power loss all point to a fuel delivery problem. Have you noticed any change in your fuel efficiency lately, besides the other issues?
