Mini Cooper misfires on models built between 2014-2018 are commonly caused by a faulty engine ECU. When this ECU fails, misfiring of the engine will occur over one or more cylinders, and will progressively become worse over time. In addition to this, further symptoms of ECU failure include the engine running rough and, in rare cases, the vehicle entering limp mode.
