Service bulletins for the 2018 BMW 440i

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.

190 on file from NHTSA, as of 2026-10-19.

B1201192019-02-25. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. SERVICE ACTION: PROGRAM THE DIGITAL MOTOR ELECTRONICS (DME). In the DME control unit software.
B6211182019-02-25. Service bulletin. ELECTRICAL SYSTEM. BLACK SPOT IN THE CENTRAL INFORMATION. This Service Information bulletin replaces SI B62 11 18 dated January 2019. Whats New: â?¢ Warranty section - Programming information added. A small black spot remains on the Central Information Displays (CID) illuminated screen which does not go away after a key cycle or sleep mode.
B6211162018-12-10. Service bulletin. ELECTRICAL SYSTEM. Center Information Display Switching off. INFORMATION The brightness of the CID will reduce and may switch off completely due to high temperature rise inside the vehicle. This situation is to protect the function of the CID. After lowering the temperature, the normal functions are restored. The increased temperature, protective switch-off is the reason for the fault. The fault code does not indicate a defective head unit. The normal maximum temperature operation for the head unit is between 167 and 194 F. Within these values, the CID will gradually diminish in brightness until it completely switches off. Replacing parts or programing the vehicle will not rectify the situation. The root cause is the very high temperature and is not a fault of the vehicle's systems.

INFORMATION Documents have been developed showing the known correct statuses for all hall sensors and micro switches used to operate the retractable hard top (RHT). This document is intended to act as a supplement to the diagnostic information available in ISTA. Comparing these statuses to the actual statuses of a vehicle with a functional problem may assist in narrowing down which sensor/switch is contributing to the functional problem. For E93, the status request may be found by connecting the car to ISTA and selecting: Control module functions/CTM Convertible top module/Diagnosis Requests ?Sensors/Switches For F33/F83, the statuses should be checked using the applicable test plan as instructed in attachment B54 09 07 F33 F83 RHT Status.pdf. For I15, the statuses should be checked using the applicable test plan as instructed in attachment B54 09 07 I15 Top Status.pd

B8402142018-12-03. Service bulletin. ELECTRICAL SYSTEM. ?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.
B1207182018-11-26. Service bulletin. ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING. DME FC 1C0102 IS STORED WITH NO OTHER RELATED FAULTS. The following fault has been stored in the Digital Motor electronics (DME) fault memory with no other engine oil pressure faults stored: ??1C0102 - oil pressure control, plausibility, static: Pressure too low This fault will not cause a customer complaint or a Check Control Message (CCM). The fault is typically identified during unrelated diagnostics. Software error in the Digital Motor Electronics (DME) may cause the fault code to be erroneously stored. Only Integration level 17-11-5xx and higher are affected.
B6130172018-11-26. Service bulletin. ELECTRICAL SYSTEM. RAIN/LIGHT SENSOR (RLS): OIL LEAKAGE FROM GEL PAD. ??Oil leaking from the Rain/Light Sensor (RLS). Note: This oil serves as a separation medium between the RLS mounting gel pad and the windscreen. The oil ensures damage free disassembly in case of repair. CAUSE The oil that serves as the separation medium of the Rain/Light Sensor (RLS) gel pad and the windscreen leaks out. Expose the Rain/Light Sensor (RLS) and properly clean the area of all oily residue. Note: The separating oil usually leaks only once from the pad at the RLS. Due to the small oil quantity in the gel pad, additional oil leakage is not plausible. Leaking oil does not impair the function of the RLS.
