Loss of engine power

Hi guys, I currently have a problem with my 2010 Renault Clio gasoline engine. The check engine light is on, the engine sometimes just cuts out, has hardly any power, runs out of round and chokes when accelerating. There is a strong smell coming from the exhaust. I have a suspicion that it could be misfiring. Have any of you had similar experiences with this and can tell me what exactly was done in the workshop to fix the problem? I would appreciate any tips and your experience.

Hi, I have some experience with cars and had a similar problem with my 2008 Renault Megane, something similar to your Clio. In my case the engine control unit was faulty. To fix the problem, I had to go to a garage and have the ECU replaced. The cost of the repair was around 1000 euros. However, as you have a different model, the exact fault could vary. Could you please share some information about your vehicle - mileage, condition, previous repairs etc. so that I can help you better?

Hey, thanks for the quick reply. My Clio has now covered almost 43530 km. The last inspection was only recently, but nothing special was found. Apart from the usual wear parts and an oil change, nothing has been repaired yet. The condition is generally pretty good, at least that's what I would have said, except for this current problem with the engine. The MOT has always passed without any defects. But maybe I really need to have the control unit checked. What exactly did you have replaced? Was it the entire control unit or just part of it? And how did you realize that this was the problem?

Hello again! In my case, the entire engine control unit was replaced. However, it is not always necessary to replace the entire block. Sometimes it can also be a small sensor on the engine control unit that leads to such symptoms. In my case, there was a specific error code that the diagnostic device read out. However, as your Clio still seems to be in very good condition overall and has been driven relatively little, I could well imagine that it could be something else. Ultimately, however, you probably have no choice but to have the fault memory read out if you want to know exactly what's wrong. Hopefully it's nothing serious and can be fixed quickly. Good luck!

Thank you for your reply and the helpful information. Yes, that makes perfect sense. The problem with the engine is really annoying and I hope it's nothing too serious. I will definitely make an appointment at the garage as soon as possible and have the fault memory read out. Hopefully the problem will be found and fixed quickly. I will keep you up to date. Thanks again for your help and good wishes, it really means a lot to me!

Hen ,clio 2008 gasoline, chokes when I go to accelerate, press the pedal to the floor, and rushes the engine then it is usually possible to continue driving. Recently after about 5 min. driving, 3 lights started to light up: warning light for electronic error ,control light for preheating and warning light for exhaust control. Anyone who has an idea. mvh stig

It sounds like your vehicle is experiencing multiple issues. The choking when accelerating could be due to a clogged fuel filter or a malfunctioning throttle position sensor. The warning lights indicate issues with the electronics, preheating, and exhaust control, which could be related to the engine control unit or the exhaust system. I would recommend getting a diagnostic scan to identify the specific error codes. This will help pinpoint the exact issues. Please update us on the progress. Remember, if you're not comfortable doing this yourself, it's always best to have a professional mechanic look at it.

Thanks for the reply, will check out the throttle.

Please do so and let us know how it goes. If the problem persists, I would recommend getting a diagnostic scan as the next step. Do you have any other questions or concerns?

Hi got error code on catalytic converter, it is replaced, the problem remains.The workshop has changed the wiring from accelerator pedal same error can not accelerate, chokes. A thought ,the speed controller ? Have left it at Autoekonom in Skövde, thinking of leaving it at Brandt renault workshop, 2400 kr for diagonstik a bit expensive I think but..... mvh Stig

Since the catalytic converter and wiring have been replaced without resolving the issue, it might be worth checking the Mass Air Flow (MAF) sensor or the throttle body for any faults or blockages. These components can affect acceleration and engine performance. If the speed controller is suspected, ensure it's thoroughly inspected as well. Please keep us updated on any progress or findings. If you have further questions, feel free to ask.
