Mini Cabrio Cold Start Problems
Summary of the thread

A similar issue was resolved by replacing a defective injector after an injector test confirmed the problem. Following this advice, the injector was replaced, resolving the cold start issues.

Thanks for the quick response. Could you elaborate on the injector cleaning or test you mentioned? What exactly did it involve, and did it resolve your issue permanently? Also, were your engine misfires during the cold start phase as well?

Indeed, my engine misfired specifically during cold starts. Cleaning didn't fix it for me; the injector test confirmed the injection valve was defective, requiring replacement. Given your symptoms, I would recommend taking it to a workshop for a proper diagnosis. They can perform an injector test to pinpoint the problem.

Just wanted to update this thread: I followed your advice and took the Mini to a workshop. An injector test confirmed the defect. Replacement of the faulty cold start injector resolved the issue. The engine now starts perfectly, even when cold. The repair cost me 515€. Thanks again for your help!

Rough idle and hard starting on your Mini Cabrio sound like classic injector problems. I had similar symptoms on my Mini, and it turned out to be a faulty injector. Did you consider an injector cleaning or test?
