Mini Cooper engine idling rough

Interesting. I had a similar issue with my Mini a few years back. Also noticed some uneven idling. Was the error code specifically pointing to the engine mount? Have you checked the rubber mount for any visible signs of mount wear or damage? Sometimes a visual inspection can tell you a lot before you even start diagnosing electrical connections. Is the engine mount itself visibly worn or cracked perhaps?

Alright, so the error code points to the mount, but you see no visible damage. The rubber mount is part of the engine mount itself, designed to absorb vibrations. Look closely for cracks, tears, or excessive wear in the rubber. If you can't see anything obvious, and the error code is consistent, it is likely an internal failure within the mount or a connection issue as you suspected. Given the cost estimate, I'd advise having a workshop inspect it, especially the mounting bracket itself.

The error code did point to the engine mount. I didn't see any visible damage though, just the error code and the uneven idle. I'm not really sure what to look for, honestly. You mentioned checking the rubber mount where exactly is that located? And what kind of damage am I supposed to be seeing?

It was indeed a faulty engine mount! The error code pointed them right to it. I ended up paying 95€, which is fine I guess. Thanks a lot for your help and shared experience!
