Mini One Diesel Fault Memory Lock Active Error

I am experiencing a 'Fault memory lock active' error on my 2015 Mini One diesel. An error is stored in the error memory. Initial diagnostics suggest undervoltage in the vehicle. Any insight into the underlying cause and potential remedies would be appreciated. It looks like the ECU fault is in active memory.

Fault codes pertaining to car electronics and an active memory lock often point to power supply anomalies. Has there been any recent work done on the vehicle's electrical system, ECU fault, or diagnostic procedures performed prior to this issue?

Regarding the power supply, should I check the battery connections and voltage regulator first? Are there specific parameters to look for with automotive diagnostics that would indicate a definitive undervoltage condition rather than a transient anomaly? I want to ensure a robust fix.

An undervoltage situation can indeed trigger a fault memory lock. Confirm the battery's health under load and rule out parasitic draws. However, given the active memory status, the issue may necessitate a professional reset and further diagnostics. Consider a workshop visit.

Understood. The Mini One is now back on the road. The fault memory lock was indeed due to undervoltage. A reset was performed, and the system is functioning as expected. Total cost was 240€ Thank you for your insights.
