Black smoke from exhaust on acceleration

Strong exhaust smell

Hi guys, I have a strange problem with my Renault Kangoo year 2016, gasoline engine. There is black smoke coming out of the exhaust when accelerating, the check engine light is on, the engine power is reduced, there is an exhaust leak and a strong exhaust smell. I suspect a fault in the exhaust aftertreatment system. Has anyone had similar experiences and can give me some tips? I would like to know how the garage solved the problem. Thanks in advance.

Hi, I had a similar problem with my 2014 Renault Megane. I'm by no means an expert, but I do have a little experience with cars. In the workshop it was found that the defect was one of the lambda sensors. The repair costs amounted to 375 euros. So it could be that your Kangoo has a similar problem. But to analyze the matter a bit more precisely, could you provide some additional data about your vehicle? Mileage, average consumption and when the last service was carried out would be helpful to help you better.

Many thanks for the feedback. My Kangoo now has 101626 kilometers on the clock and unfortunately nothing special was found during the last service. The average consumption is around 7.8 liters per 100 kilometers. Now that you mention it, it could well be that there is something wrong with the lambda sensors. Thanks for the tip, I'll definitely pass it on to the mechanic!

No problem, you're welcome! I'm glad I was able to help you with my experience. Yes, your mileage is definitely in the range where the lambda sensor could give up the ghost. By referring to the lambda sensor, you can ask your mechanic to check it more closely. If it really is the problem, I hope that the costs will be lower for you than for my Megane. In any case, let us know how it goes. Good luck!
