Problems with Renault Kadjar 2019: Unsteady engine, acceleration problems and black smoke - suspected faulty injection valve

Hi guys, I have a problem with my 2019 Renault Kadjar petrol engine. It doesn't pull properly anymore, the engine runs rough, jerks when accelerating, has longer cold start times and black smoke comes out of the exhaust. Even starting is sometimes a problem and it occasionally stalls when idling. The check engine light is also on. I suspect it could be due to a faulty fuel injector. Have any of you ever had similar problems and can give me some troubleshooting tips? I would be particularly interested in your experiences with the workshop and how the problem was resolved. Thank you very much!

A 2019 Renault Kadjar is experiencing issues such as unsteady engine performance, acceleration problems, longer cold start times, black smoke from the exhaust, and occasional stalling. The check engine light is on, and a faulty fuel injector is suspected as the cause. A similar issue in a Renault Scenic was resolved by replacing a faulty plug/cable connection, suggesting a potential solution for the Kadjar's problems. Further diagnostics, including reading error codes, are planned to confirm the cause and guide repairs.

Hi, Had a similar problem with my 2017 Renault Scenic. Not a car expert, would describe myself as someone with some experience. Longer cold start time and the jerking, that's exactly how it was with me. I had it checked at my garage. When they checked it, they found that the plug/cable connection was faulty. I had to have the cable connection replaced, which cost me 155 euros. Is it similar for you? What error codes did your on-board computer display? More information could help with troubleshooting. Hope this helps you!

Hi, thanks for the quick reply! Unfortunately, I haven't read out the exact error codes yet, but I'll do that in the next few days and post it here. I currently have 54095 km on my Renault Kadjar and the last service was about six months ago. I really hope it's as "simple" as yours. I'll keep you all posted if there's any news! See you then!

Hey, all right, let's hope for the best. Who knows, maybe it really is just a minor issue like mine back then. If you have the error codes ready, I can look over them again, maybe I'll recognize something. I'm looking forward to your news. So, keep in touch, eh? Good luck with it and see you next time!
