Black smoke and loss of power in a 2016 Opel Karl: experience and advice wanted

Black smoke from exhaust on acceleration

Hi guys, I have a few concerns about my 2016 petrol Opel Karl with a whopping 123353km on the clock. When accelerating it blows black smoke out of the exhaust, has an illuminated check engine light, a noticeable loss of engine power, an exhaust leak and a strong exhaust odor. I assume it could be a malfunction in the exhaust aftertreatment system. Has anyone had similar problems? What was your experience at the mechanic, especially as I didn't have such a good experience last time. Your advice and experience would really help me! Thanks in advance!

Hello, I had a similar problem with my 2013 petrol Opel Corsa. One of the lambda sensors was defective. It was indeed a serious problem, as the lambda sensor index has a significant impact on fuel consumption and engine performance. In addition, the vehicle produces more harmful exhaust gases if it is defective. We had to replace the sensors altogether. It was a major job, but after it was fixed, my car ran like new and the symptoms you describe were gone. So yes, it could be a malfunction in the exhaust aftertreatment system. It's best to go to a mechanic you trust. In my case, the repair at the garage worked pretty well. Good luck and hopefully it's nothing too serious!

Hello, thanks for the quick reply and the helpful insight. I'm glad that your car is running smoothly again. Can you remember how much the whole thing cost you? And has anything new come up since the repair that might be related to the previous problem? Thanks again!

Hello, sure, no problem! So, the repair of the lambda sensor cost me €375. Pretty hefty, but since then my little Corsa has been running like clockwork and that annoying check engine light has stopped flashing. No more worries about black smoke or exhaust smell. In general, the problem with the exhaust aftertreatment malfunction has been fixed since the visit to the mechanic. So far, nothing new has come up that I could link to the previous issue. All in all, I can say that the investment has paid off. My tip to you - go to a good mechanic that you feel comfortable with. In the end, it can save you unnecessary headaches and costs. You're welcome! Hopefully I've been able to help you.

Hello, thank you for the details and the encouraging words. It sounds like although the initial cost is high, it may be worth it in the medium to long term. I will definitely visit a trusted mechanic and describe my situation. I hope this will help improve the performance of my car and reduce exhaust emissions. Your advice has really helped me gain perspective. Thanks again! Take care and happy driving always!
