Intermittent performance or rough running without a relevant DME fault stored The most likely cause is that an ignition coil has failed, which in many cases can be confirmed with basic diagnosis.

M6106072023-11-01. Service bulletin. MINI electrical systems have continued to develop over the past few years. As a result, the demand on the batteries has increased. Breakdowns due to an empty battery or problems in the vehicles electrical system can have various causes, most of which are not due to the battery itself. For this reason, a battery replacement will permanently eliminate the problem only in the rarest of cases. The energy diagnosis test module helps to localize these causes. This document covers important information for the dealer on how to handle “discharged battery” complaints. Without performing the energy diagnosis test plan, the root cause of a discharged battery cannot be identified. In order to properly repair the vehicle the first time, it is very important that the diagnostic test plan is performed to completion; with all results taken into consideration.
