Mini Paceman Battery Weakness and Lighting Flicker

A similar issue presented itself on my previous vehicle, a Volvo. The symptoms you describe, specifically the weak start and flickering lights, are indicative of a potential problem within the battery management system. Have you performed any battery testing to ascertain the current battery voltage under load? A failing voltage sensor can certainly mimic the behaviour of a degraded car battery. We can proceed methodically to examine all pertinent parameters.

Thank you for the prompt response. Could you elaborate on the testing procedures you employed with your Volvo? Were there specific voltage thresholds or diagnostic codes that ultimately led to the voltage sensor being identified as the source of the problem? I have access to a multimeter, and I am prepared to conduct further battery health assessments on my Mini Paceman.

Affirmative, the symptoms align with a failing voltage sensor. In the Volvo, the battery voltage readings were erratic and outside of the established tolerances. The diagnostic trouble codes pointed towards a communication fault within the battery monitoring system. Given the age of your Mini Paceman, and the mileage, the probability of a sensor malfunction is substantial. Consider a professional diagnostic assessment from a qualified technician to corroborate this preliminary diagnosis. It is advisable to proceed with replacement to pre-empt any system wide electrical complications.

I appreciate your insights. The diagnosis at the workshop confirmed the defective battery voltage sensor on my Mini Paceman. Replacement cost 315€. It seems the weak battery voltage and flickering lights were indeed caused by this sensor malfunction. Replacing it resolved the issue.
