Mini Roadster engine issues

Rough engine running and stalling at idle sounds familiar. I had a similar issue with my Mini Roadster. The check engine light was on, and it felt like the engine was about to give up sometimes. Have you checked the coil pack? It might be a faulty ignition coil. Think of it like a bad spark plug, but instead of just one cylinder misfiring, it can affect multiple ones.

Interesting. When you say 'coil pack', are you referring to the ignition coil itself? And did you also experience jerking when accelerating? The Roadster has been doing that too.

Yes, by 'coil pack' I mean the ignition coil. And yes, the jerking when accelerating was definitely part of the problem. It felt like the car was hesitating. Given your symptoms, I'd bet it's a defective ignition coil. It is best to get a proper vehicle diagnostics done, but I would recommend a workshop visit.

Just wanted to update you I got it sorted. The vehicle diagnostics confirmed it was indeed a defective ignition coil, like you suggested. Apparently, the cable connection was faulty. All in, it cost me 95€ to repair. Thanks for pointing me in the right direction!
