Hey, sure, I can tell you! So, after I went to the garage, they actually found that the ignition coil was defective and there were misfires. That was then all fixed. However, the biggest chunk was really the engine control unit. That cost me almost exactly €1000. Since then, my Mini has been running like a champ again and I've had no further problems. Hope this helps you! Good luck and best wishes!

Hey everyone, thanks for the quick replies! After reading your comments, I decided to go to the mechanic, even though I was a bit skeptical. So, off to my trusted garage. Once there, I described the symptoms to the mechanic and he first read out the engine control unit. Lo and behold, there were various error codes. It turned out that there were actually several problems: the ignition coil was broken and the engine control unit was also faulty. The mechanic replaced both and recalibrated some sensors. All in all, it cost me just under 1100€. Now my Mini is running like clockwork again and my worries are gone for the time being. I hope it stays that way! Thanks again for your tips and experience! Best regards!

Hey, had similar problems with my 2018 Mini Clubman. In my case, the engine control unit was actually defective. The symptoms were almost identical: black smoke, check engine light, loss of power, jerky engine running and high fuel consumption. The engine control unit was read out in the workshop and many error codes were discovered. It turned out that the electronics had partially failed, causing various sensors and actuators to receive incorrect signals. In the end, the control unit was replaced. This was a serious problem, as the control unit is the "brain" of the engine. If you have similar symptoms, I would have the engine control unit checked if I were you. A competent workshop should be able to determine this quickly. Good luck!
