BMW 5 Series model year 2017: Black smoke, loss of power and malfunction when idling

Hi, something similar happened to me with my 2015 BMW 5 series. I don't have that much experience with cars, but I fixed the problem at my garage. It turned out that the injection valve was dirty. The whole thing cost me around 515 euros. So, it could well be that you have the same problem. But can you give us the exact engine designation and mileage? That would certainly help us to help you more accurately. Good luck with that!

Hello, thank you for your answer! My BMW has an engine with the designation N20 and has 84635 km on it. I hope that helps! I'll follow your advice and have the injection valve checked at my garage. Let's hope that this solves the problem. Thanks again for the tips!

Hey, no problem, you're welcome! Your information is very helpful. I'm familiar with the N20 engine, as mine has the same one. I had the same problems with similar mileage as you are having now. I strongly assume that it's also the injection valve in your case. Try it out and then report back how it went. Hopefully it's nothing more serious and your problems will be solved. By the way, remember to check the fuel filters as well, sometimes they can be clogged and cause similar symptoms. Good luck and I hope your BMW runs smoothly again soon!
