M3401132018-12-03. Service bulletin. SERVICE BRAKES, HYDRAULIC. "Erroneous ""Service due"" Message Though Brake Lining Thickness Sufficient. The CBS data calculated for the remaining distance of the front and/or rear brake pads does not agree with the actual brake pad thickness. The yellow brake lining service due indicator illuminates even though the pad thickness is greater than the minimum wear limit (approximately 3.7 mm); the brake wear sensor has not yet been activated (from a thickness of approx. 4.2 mm). In some cases, the red warning message may already be active. The CBS front/rear brake display is based on a mathematical calculation. Various influences are incorporated into this calculation (for example, vehicle speed, brake pressure, and rotor temperature). Due to changing driving characteristics and/or unfavorable environmental conditions, the calculated remaining distance may differ from actual pad thickness."

"PERFORM THE PROCEDURE OUTLINED IN THIS SERVICE INFORMATION ON ALL AFFECTED VEHICLES BEFORE CUSTOMER DELIVERY OR THE NEXT TIME THEY ARE IN THE SHOP FOR MAINTENANCE OR REPAIRS. SUBJECT Service Action: Retrofit of Engine Coolant Temperature Sensor. Internal corrosion can form in the engine coolant temperature sensor. This corrosion leads to internal bridging of the contacts, which can cause an inaccurate engine temperature reading. This false reading can lead to difficulty in the engine starting and/or a ""Service Engine Soon"" lamp being illuminated."
M1101122018-12-03. Service bulletin. ENGINE. The customer states that a small engine oil leak can be seen from the underside of the engine. CAUSE The internal sealing of the oil pump volume control solenoid valve is compromised, allowing engine oil to leak from the oil pump volume control solenoid.
M3403132018-12-03. Service bulletin. SERVICE BRAKES. Brake Fluid Maintenance Service: 36-Month Interval. The coding in these vehicles has the CBS displaying the first brake fluid service as a 36-month interval from the date of production, instead of the appropriate 24-month interval.
M6106072018-11-26. Service bulletin. VEHICLE SPEED CONTROL; 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 repair the vehicle properly the first time in the workshop, the diagnostic test plans must be performed to completion, with all results taken into consideration. Without performing the energy diagnosis test plan, the root cause of the discharged battery cannot be identified. This increases the chances of a repeat repair. CAUSE Discharged battery."
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.
M1103092018-11-26. Service bulletin. ENGINE. Whistling Noise from the Water Pump Area. A whistling or squealing noise is heard from the engine at idle and/or at higher engine speeds. CAUSE 1. Noise is caused by the water pump. 2. Noise is caused by the friction wheel of the belt tensioner.
