Hey, thanks for the quick reply! With my Latitude, the problem mainly occurs when I've been driving a bit longer, after about 30 minutes of driving. When the car is cold, it seems to work at first. But after about half an hour the engine starts spinning. However, the latest check was carried out at a mileage of 90362 km and no problems were found. Do you have any idea what this could be? I look forward to your feedback!

Hey, thanks for the additional information. With my Laguna, the problem persisted regardless of the driving time. The fact that it only occurs after about half an hour in your case could indicate that it's a heat-related problem. It could be that one of the engine components - possibly the engine control unit or the ignition system - is not working properly at high temperatures. The exhaust system could also be affected. However, it is interesting to note that no defects were found during the inspection. This indicates that the problem is either sporadic or that it only occurs when the engine is running and disappears again when it is switched off. In your case, I would really recommend going to a garage and having the car checked after a long drive if the problem is active. A professional diagnostic scan could then help to determine the exact problem. Sorry I can't give you a definite solution - there could be a number of reasons it really is best to take it to a professional. I hope I've been able to help you a bit though!

Hey, thanks for your detailed reply and your advice. I will definitely follow your recommendation and visit a garage. On the one hand, of course, I hope it's nothing serious. But on the other hand, of course, the problem needs to be fixed. I'll keep you posted. It was helpful to hear your experiences! Thanks again for taking the time!

Hello! I am currently experiencing the same problems as described by you. Engine goes ok while in the first 10-20 minutes from the start, then it’s lile getting tired or something and refuses to do overtakes. And when it runs good I can smell som oil from inside the car also when flatting it out

Based on the symptoms you've described, it could be a number of issues. However, a common cause for these symptoms is a failing or clogged fuel injector. This can cause the engine to run lean, leading to poor performance and increased fuel consumption. It can also cause a strong fuel smell. I recommend having your fuel injectors checked and cleaned if necessary. If the problem persists, it would be best to have a professional mechanic perform a thorough inspection. Please keep us updated on your progress.

What was the problem and how did you manage to get it working well again?
Flavian, it's also possible that your vehicle's catalytic converter is failing. This could explain the smell of oil and the decrease in performance after driving for a while. The catalytic converter is responsible for converting harmful emissions into less harmful substances. When it fails, it can cause a variety of issues including poor engine performance and increased emissions. I would recommend having your vehicle inspected by a professional mechanic to confirm this. Please keep us updated on your progress. Do you have any further questions?

Hello! Thank you for the advice! Went to a mechanic and diagnosed the car… you were right, it had a bad sensor on the DPF (the pressure of evacuation gas sensor) which gave a few of the sympthoms, and we also found out the thermostat was also malfunctioning so we changed it and changed the vacuum pump gasket cause it was loose and it was leaking oil. On the tester the injection system didn’t give any errors and the injectors were on normal parameters. I will drive the car to see if will be any improvements… if needed, I will take the injectors to a more detailed check. Take care and have a good day!

I'm glad to hear that you've made progress with your vehicle, Flavian. It's good that you've replaced the faulty sensor and thermostat, and fixed the oil leak. These repairs should definitely improve the performance of your car. Please continue to monitor your car's behavior, especially during acceleration and longer drives. If you notice any of the previous symptoms returning, it would be a good idea to have those injectors checked as you mentioned. Please keep us updated on how your car is running. Do you have any other questions or concerns?
Hey, I have a bit of experience with cars. I own a Renault Laguna, built in 2010, so quite similar to yours. It had a similar problem. It turned out that the engine control unit was faulty. I had to have it repaired at the garage and it actually cost me 1000 euros. The repair process took a few days, but after that the car was good to go again. Overall, the service at the garage was solid and they were able to identify and fix the problem quite quickly. Your symptoms sound similar to my case. So it could be the engine control unit, but without exact vehicle information and condition it's hard to say. Can you share more details about the driving behavior of your car and when exactly the problems occur? That way I might be able to help you more accurately.
