Service bulletins for the 2014 BMW 328d

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.

1616142018-11-13. Service bulletin. ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM. Service Engine Soon Light (MIL) is On with SCR Fault 805220 Stored. The Service Engine Soon light is on with the following fault stored in the Selective Catalyst Reduction module (SCR). z 805220 - Delivery module, system pressure, pressure build-up is too low. This fault is very likely to be stored at temperatures below 32°F / 0°C if the vehicle is programmed using ISTA/P 3.54.1 or 3.54.2. Unfavorable SCR software
8402142018-11-13. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. ConnectedDrive/BMW Assist System Diagnosis Information. ConnectedDrive/BMW Assist features are partially or completely inoperative. This Service Information bulletin is being published because vehicles are down for an extended period of time when researching system failures with ConnectedDrive or BMW Assist. This Service Information bulletin will assist you both in identifying the issue and providing technical support. CAUSE Not enough information is available for BMW NA engineers to assist the technician in diagnosing the root cause.
6103142018-11-13. 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 be stored: * 213901 - Power management: Reduction or shutdown of individual electrical consumer * 8040BD - Reset or deactivation of Terminal 30F * 8040B9 - De-activation of terminal 30B: Top start capability limit reached * 8020E8 - Reset or deactivation of terminal 30F * 800E89 - FRM: start capability limit reached with lights active during stationary mode * 93076B - Deactivation of terminal 30B: upper start capability limit reached * 93076A - Deactivation of terminal 15: upper start capability limit reached, but deactivation preventer active * 93076C - Deactivation of terminal 30B: upper start capability limit reached, but deactivation preventer or legal loads active * 930769 - Deactivation of terminal 15: upper start capability limit reached Note: 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 shut
1303142018-11-13. Service bulletin. ELECTRICAL SYSTEM. Service Engine Soon Lamp (MIL) On with NOx Sensor Faults Stored. The Service Engine Soon lamp (MIL) is on with either of the following nitrogen oxide (NOx) sensor faults stored: * 2B6200 - NOx sensor before DeNOx catalytic converter, plausibility: Sensor self-diagnosis of sensitivity * 2B6300 - NOx sensor After DeNOx catalytic converter, plausibility: Sensor self-diagnosis of sensitivity These stored faults would not cause a problem with engine performance. This NOx self-diagnostic routine is performed only after the engine has been shut off. In some situations, the diagnostic function of both NOx sensors can be too sensitive when sampling the residual exhaust gases, leading to an erroneous fault being set. Unfavorable DDE software diagnostics
