6504142018-11-05. Service bulletin. AIR BAGS. "Airbag Warning Light: ACSM FC 930A60 or 930A1C Seat Occupancy Detection. According to the customer, the airbag warning light was on, but it may not be on when the vehicle arrives in the workshop. 1. ACSM fault code ""930A60 - Seat occupancy detection, front passenger; malfunction"" is stored. The fault may or may not currently be present. Or 2. ACSM fault code ""930A1C - Seat occupancy detection, front passenger; malfunction"" is stored. The fault may or may not currently be present. CAUSE The front passenger seat occupancy mat consists of a seat occupancy mat with a capacitive sensor system. This means a front passenger is detected by measuring the resistance of the human body. The fault is set when moisture is detected on the mat itself."
6130142018-11-05. Service bulletin. ELECTRICAL SYSTEM. "SI B61 30 14February 2015 General Electrical SystemsTechnical Service This Service Information bulletin supersedes SI B61 30 14 dated January 2015. designates changes to this revision SUBJECT BMW Maintenance Program: 12-Volt Battery Replacement Measure. INFORMATION This bulletin outlines a customer satisfaction measure that has been designed exclusively for the BMW vehicles listed above. It involves the replacement of the 12-volt battery as a preventive maintenance measure. This 12-volt battery replacement measure is: ? Effective for repairs dated on or after January 1, 2015. ? Applicable to vehicles that are still covered by the BMW Maintenance Program. This program is valid for 4 years or 50,000 miles, whichever occurs first. ? The calculation is based on the current date of repair. It is ""applicable"" when the 12-volt battery was not replaced within the last 12 months. You can then perform the battery replacement as outlined below. Please check the warranty claim history for the specific vehicle in the DCSnet Warranty Vehicle Inquiry to confirm the battery was not already replaced within the previous 12 months."
6103142018-11-05. Service bulletin. ELECTRICAL SYSTEM; POWER TRAIN. Check Control Messages Related to Battery Charge During Cold Ambient Temperatures. On cold days with an outside ambient temperature of less than 15°F, customers may notice a check control message related to the battery that is displayed on the instrument cluster and the control information display. Under these conditions, the vehicle starts. Various power management faults can be stored. When the outside temperatures drop below 46°F, the charging system is switch to full charge. CAUSE ? The check control message (ID 229) is caused by a heavily discharged battery. ? The check control message is triggered when the current state of charge (SoC) of the battery approaches the minimum SoC that is required to start the vehicle (start capability limit). ? In low outside ambient temperatures, the start capability limit of the vehicle is higher. Therefore it takes more energy from the battery to start a cold engine. ? Without the early warning of the check control message, the current state of charge would drop below the start capability limit and the vehicle would not start. ? The vehicle's intelligent power management system actively takes measures to increase the charge of the battery, such as increasing idle speed and reducing or shutting down certain electrical consumers.
2702132018-11-05. Service bulletin. ELECTRICAL SYSTEM; POWER TRAIN. SI B27 02 13February 2015 Intermediate and Special Transmission Technical Service This Service Information bulletin supersedes SI B27 02 13 dated June 2013. designates changes to this revision SUBJECT Knocking Noise from Driveline During Low-speed Turning.

1116142018-11-05. Service bulletin. ENGINE. "This Service Information bulletin and attachment supersedes SI B11 16 14 dated January 2015. designates changes to this revision SUBJECT N63 Engine: Check the Timing Chain. INFORMATION This bulletin outlines the procedure for checking the engine timing chains for wear, and should be completed in conjunction with SI B11 06 14, ""N63 Customer Care Package."" The N63CCP and N63 Engine Check the Timing Chain are NOT mandatory Technical Campaigns or Recalls. They should be completed only based on parts availability, workshop capacity, and the customer's schedule. Performing the test plans identified in the procedure below will detect wear at an early stage and, if necessary, provide a repair solution. To avoid future valvetrain wear, the vehicle must be reprogrammed and a shorter oil service interval must be retrofitted via ISTA/P. Finally, drain and replace the engine's oil and filter. After completing all necessary repairs included in the N63 Customer Care Package and the Timing Chain Check, the vehicle must be test driven for up to 30 minutes to ensure that the repairs were performed to the highest standard."

B6523162018-11-05. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; EQUIPMENT; EQUIPMENT:ELECTRICAL:RADIO/TAPE DECK/CD ETC.. ?AUDIO VOLUME NOT RESTORED AFTER MSA STOP, ENTRY HEAD UNIT. Volume of audio system (when set to near maximum) is reduced when Auto Start-Stop (MSA) stop occurs and is not restored upon automatic engine restart. This is normal system behavior - serves to protect the head unit, battery drain and avoidance of incremental leaps in the loudness. The loudness is reduced to 2/3 of maximum and is not restored. Note: Air conditioning output is also reduced upon MSA stop and is not restored for similar reasons.
B3405162018-11-05. Service bulletin. SERVICE BRAKES. CBS BRAKE PAD CALCULATION AND CORRECTION. When a vehicle comes into the workshop for any repair or maintenance job, the bundling calculator recommends a brake maintenance checkup. No brake warning light is illuminated. CBS shows 3,107 miles or slightly higher for the next brake service displayed via Key Reader, or vehicle's Control Display (in Vehicle Info/Status/Service required/Brake pads) CAUSE CBS calculates the remaining brake pad wear based on brake pressure, speed, vehicle specific parameters (i.e. NAO pads), brake temperature as well as cumulative brake application time. Due to variation of these parameters and outside environmental influences, this calculation can deviate from the real brake pad wear. Starting from the above-mentioned production dates of the vehicles indicated, the CBS brake pad wear calculation has been changed, and is now based only on the brake pad wear sensor. Important Note: To avoid a too-slow wear prediction, the CBS brake model will estimate the need for repairs, in some cases, rather early. Calculation will level at 3,107 miles and stay at this value until the CBS brake pad wear sensor is triggered. https://www.bmwtis.net/tiscode/cgi-bin/bulletin.aspx?sie_path=/tsb/bulletins/htm_store/36...11/8/2016 Page 2 of 2 After the sensor is triggered, the CBS mileage will count down indicating to the customer that the brake repairs will be due.

B0703142018-11-05. Service bulletin. ELECTRICAL SYSTEM. Diagnosing Stored Fault Codes to Help Avoid Repeat Repair Visits This Service Information bulletin supersedes SI B07 03 14 dated October 2015.. Fault codes stored in vehicles being serviced are not being diagnosed, leading to repeat repair visits (source- Analysis of FASTA data and repeat repair visit reports). INFORMATION Where diagnosis (vehicle or short test) with ISTA has already started, it is important to diagnose the fault code(s) listed below (when they are stored in the vehicle) to find their root cause during the current workshop visit. This will help lead to a reduction in workshop repeat repair visits and higher customer satisfaction.
