M6106072023-11-01. Service bulletin. ELECTRICAL SYSTEM. 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.
M3601192022-01-24. Service bulletin. ELECTRICAL SYSTEM; WHEELS; EQUIPMENT. New RDC wheel electronics will be introduced with future generation MINI models. The new wheel electronics are identified as Huf Generation 5. These new wheel electronics will need to be programmed using the new tool when replaced or when depressurized (0 psi) for more than 2 minutes.
M0104192020-02-18. Service bulletin. ELECTRICAL SYSTEM; ENGINE; FUEL SYSTEM, GASOLINE. CLASS ACTION SETTLEMENT: N14 HIGH-PRESSURE FUEL PUMP (HDP) SERVICE BENEFIT CLASS VEHICLES: The MINI vehicle may experience a sudden engine operational failure reduced or loss of power while driving and the malfunction indicator lamp (MIL) may be illuminated along with high-pressure fuel pumprelated faults stored in the Engine Control Module (DME).

M1201152018-12-10. Service bulletin. ELECTRICAL SYSTEM; ELECTRICAL SYSTEM:IGNITION. Engine Misfire Due to Failed Ignition Coil This Service Information bulletin supersedes SI M12 01 15 dated March 2016.. The Check Engine or Service Engine Soon (MIL) lamp is on with misfire fault(s) stored in the DME. 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. During operation with high temperature fluctuations, the different materials used in the Bosch ignition coil construction can deteriorate over time, leading to a failure.

M6106072018-12-03. Service bulletin. ELECTRICAL SYSTEM. "Discharged Battery: Energy Diagnosis Must Be Performed. MINI electrical systems and advancements in vehicle technology have resulted in an increased demand on the vehicle battery. This SI will help the dealer handle ""discharged battery"" complaints. A discharged battery can have various causes, most unrelated to the battery. A failed battery is often the symptom and not the cause. A fully serviceable battery fails when an electrical component causes the battery to discharge; the battery becomes internally damaged and must be replaced. For more information, refer to http://www.batteryuniversity.com/parttwo-42B.htm. For this reason, replacing the battery is not usually a permanent repair. The cause of the discharged battery must be analyzed in order to guarantee a proper repair. To properly repair the vehicle the first time in the workshop, the diagnostic test plans must be performed to completion, with all results taken into consideration. The procedure below will guide the technician to properly repairing the vehicle and getting paid for a warranty claim. CAUSE Discharged battery."
M6201132018-12-03. Service bulletin. ELECTRICAL SYSTEM. Intermittent Humming or Buzzing Noise from Speedometer.

M1206122018-11-26. Service bulletin. ELECTRICAL SYSTEM. Change in Thermostat Electrical Connector on Replacement Engine Harness. Vehicles produced from 3/2013 are no longer equipped with an engine coolant thermostat that incorporates the engine coolant temperature sensor (thermostat P/N 11 53 7 647 751). The engine coolant temperature sensor is now an individual component. To accommodate this component change, there was also a production change to the engine wiring harness; this also includes the replacement engine harnesses for earlier produced vehicles. The replacement harness is no longer equipped with the four pin connector for the thermostat / engine coolant temperature sensor, but two separate twopin connectors, one for the coolant thermostat and one for the engine coolant temperature sensor. *The N16 engine switched production to the 11 53 7 534 521 thermostat in 3/2012. This thermostat, like the new 751, incorporates a separate engine coolant temperature sensor. The connectors on the 521 thermostat will not match up to the connectors on a new, replacement engine harness. The 521 thermostat will need to be replaced with the 751 thermostat during this repair.
M1202122018-11-26. Service bulletin. ELECTRICAL SYSTEM; ENGINE. SI M12 02 12 Engine Electrical Systems April 2013 Technical Service . After reprogramming the vehicle to integration level R056-11-11-503 (ISTA/P P45.1.3.0) or higher, one of the following fault codes are stored in the DME fault memory: Vehicles with N16 engine: * 2F42 Engine ventilation heating, Control The Service Engine Soon lamp is not illuminated. Vehicles with N18 engine: * 37DE Engine ventilation, heating, triggering: open circuit The Service Engine Soon lamp is illuminated. CAUSE Due to a DME software change, the diagnostic monitoring capability is improved for the engine ventilation heating system. However, a fault will be stored in the fault memory because the engine ventilation heater circuit has a malfunction currently present.
M8401142018-11-13. Service bulletin. ELECTRICAL SYSTEM. iPhone: Connection Failures with iOS 7. There are various connectivity failures with the iPhone using iOS 7. Some examples are listed below: z Call disconnection z Contact List incomplete z General connection failures Apple software iOS 7 and its variants

M3401132018-11-13. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; SERVICE BRAKES, HYDRAULIC. Erroneous "Service due" Message Although Brake Lining Thickness is Above Minimum Specification. The yellow "Service Due" warning message lights up in the instrument cluster, even though the brake pad thickness is more than 4.2mm (above the thickness at which the pad sensor intervenes). The calculated remaining service life for the brake pads (front and/or rear axle) from the CBS data does not match the actual brake pad thickness. Software calculation of the brake pad wear model in the DSC.
M5103122018-11-13. Service bulletin. VISIBILITY; ELECTRICAL SYSTEM; EQUIPMENT. Window Regulators Squeak when Moving Up or Down. The front side windows can make a squeaking noise when operated.

M6504142018-11-13. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT. Automated Activation of Navigation System During PDI/QC1. INFORMATION Important: The INITIAL NAV enabling code no longer needs to be pre-ordered through the Parts department! When the vehicle is connected to the diagnostic system ISTA to perform PDI/QC1, the step to activate the navigation system (part of Delete Transport Mode) will automatically request the INITIAL NAV enabling code (VIN-specific) without pre-ordering the enabling code. This enabling code will be automatically delivered through ISTA and it then activates the navigation system. Note: This VIN-specific NAV enabling code is then also automatically stored in the Repair Kit in the Aftersales Assistance Portal (ASAP). The automated INITIAL NAV enabling code request and activation of the navigation system will take no longer than 1 minute. After finishing "Delete Transport Mode," the navigation system in the vehicle will be active without entering the 20-digit INITIAL NAV enabling code manually or in ISTA. If the navigation system is not active and asking for the enabling code, turn off the ignition and wait for the head unit to enter sleep mode (approx. 3 minutes). After that, turn on the ignition again. The head unit will start up and the navigation system is activated. If the INITIAL NAV enabling code for first-time activation of the navigation system is not requested or delivered automatically, it still can be ordered manually through the Parts department and activated in the vehicle by entering the 20-digit enabling code manually.
M6401142018-11-13. Service bulletin. ELECTRICAL SYSTEM; VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM. Automatic Deactivation of Recirculation Mode. The customer states the recirculation display goes out, even though the recirculation button was switched on. CAUSE The automatic recirculation air deactivation feature was introduced in July 2012. Note: If the customer dislikes this feature, it can be deactivated by using the following steps.
