Service bulletins for the 2012 BMW 740i

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

Vehicles which require this Service Action to be completed will show it as ""Open"" when checked either in the ""Service Menu"" of DCSnet (Dealer Communication System) or with the Key Reader. CAUSE The high-pressure pump quantity control valve may fail."
B6604152018-11-05. Service bulletin. STRUCTURE:BODY:TRUNK LID; ELECTRICAL SYSTEM:WIRING: REAR COMPARTMENT/TRUNK; LATCHES/LOCKS/LINKAGES:TRUNK LID:LOCK. Trunk Lid Does Not Operate with Remote After Programming. If the customer profile is assigned to only unlock the driver door after programming with ISTA/P 3.55.x, the trunk will not open with the remote. CAUSE Coding error in CAS (Car Access System) for trunk locking
B6509152018-11-05. Service bulletin. EQUIPMENT:ELECTRICAL:NAVIGATIONAL SYSTEM(GLOBAL POSITIONING SYSTEM); EQUIPMENT:ELECTRICAL:RADIO/TAPE DECK/CD ETC.; EQUIPMENT:ELECTRICAL; EQUIPMENT. HU-H: Headunit Resets Intermittently or Permanently. The HU-H (Headunit-High) resets intermittently or permanently. ? The display is inoperative and there is no audio output ? Automatic system start-up after a couple of seconds CAUSE Software error in the HU-H
B6103142018-11-05. Service bulletin. ELECTRICAL SYSTEM. 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 occur. 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.
B3602152018-11-05. Service bulletin. TIRES:VALVE; WHEELS. Valve Stem Replacement with Wheel Electronics. INFORMATION The valve stems are single-use only, and must be replaced every time the wheel electronics are replaced. If you loosen the nut (1), you must replace the valve stem. Failure to replace the valve stem will lead to a pressure leak. The proper repair procedure can be found in REP 3611533. Not applicable.

B1302152018-11-05. Service bulletin. FUEL SYSTEM, GASOLINE. Service Action: N63 Replace High-Pressure Fuel Pumps. The high-pressure pump may fail, resulting in an engine malfunction warning and reduced engine output.
B1116142018-11-05. Service bulletin. ENGINE. "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."

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."
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. ?

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.
B3101122018-11-05. Service bulletin. POWER TRAIN:AXLE ASSEMBLY. CLICKING NOISE FROM FRONT AXLE This Service Information bulletin supersedes SI 31 01 12 dated June 2015. Clicking noises are heard from the front axle area while maneuvering at low speeds (e.g., parking lot maneuvers). CAUSE Movement between the contact surfaces of the wheel bearing and swivel bearing (knuckle)
