Service bulletins for the 2025 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.

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

Bulletins, newest first
B1701262026-07-31. Service campaign. ENGINE. The coolant vent lines of the low-temperature circuit are designed to remove air bubbles from the system toensure optimal cooling performance. Internal quality inspections have revealed that leaks may occur due tolocalized material aging on the vent lines. These leaks occur because the material originally used is notsufficiently resistant to the continuously high temperatures. A coolant leak may result and cause a yellow check control message and reduced engine performance.
B6124252026-01-23. Service campaign. ELECTRICAL SYSTEM. A limited number of 48 (V) volt vehicle batteries may have been damaged during the manufacturing process;this could lead to a premature battery failure. The 48 V battery may fail, triggering a corresponding Check Control message.
B1601242025-11-25. Service campaign. ELECTRICAL SYSTEM. RSU availability. The engine cranks but will not start.
B1105252025-09-22. Service campaign. ENGINE. Due to an assembly error the upper oil pan screws may not have been torqued correctly.
B1105252025-09-06. Service campaign. ENGINE. Due to an assembly error the upper oil pan screws may not have been torqued correctly.
B1107252025-09-03. Service campaign. ENGINE. Due to an assembly error, the valvetrain could have a mechanical failure.
B1105252025-08-13. Service campaign. ENGINE. Due to an assembly error the upper oil pan screws may not have been torqued correctly.
B1105252025-08-01. Service campaign. ENGINE. DELIVERY STOP: OIL PAN TOP SCREW CONNECTION
B6404252025-07-31. Service campaign. ELECTRICAL SYSTEM. After performing a cabin air filter replacement maintenance service task, or after a similar repair thatrequired the removal and installation of the filter’s housing cover; the following air flap and/or air temperaturesensor faults are stored in the BCP: 80114D - Stepper motor: Unexpected error in Driving Cycle 801168 - Temperature sensor ventilation left or ventilation: short to ground 80116A - Temperature sensor ventilation right: short to ground 80116B - Temperature sensor ventilation right: short to plus or open circuit 80116C - Temperature sensor footwell left or footwell: short to ground 80116D - Temperature sensor footwell left or footwell: short to plus or open circuit 80116E - Temperature sensor footwell right: short to ground 80116F - Temperature sensor footwell right: short to plus or open circuit 80435B - Stepper motors: short-circuit by mass
B6404252025-07-28. Service campaign. ELECTRICAL SYSTEM. The following air flap and/or air temperature sensor faults are stored in the BCP. 80114D - Stepper motor: Unexpected error in Driving Cycle 801168 - Temperature sensor ventilation left or ventilation: short to ground 80116A - Temperature sensor ventilation right: short to ground 80116B - Temperature sensor ventilation right: short to plus or open circuit 80116C - Temperature sensor footwell left or footwell: short to ground 80116D - Temperature sensor footwell left or footwell: short to plus or open circuit 80116E - Temperature sensor footwell right: short to ground 80116F - Temperature sensor footwell right: short to plus or open circuit 80435B - Stepper motors: short-circuit by mass To prevent harness damage the wiring harness will receive a new retention strap the next time the vehicle comes to the shop for its cabin air filter service.
B1204252025-04-28. Service campaign. ELECTRICAL SYSTEM. As a result of a data input error, certain fault memories are permanently stored. The permanent storage offault memories does not comply with the legal specifications of the authority (California Air Resources Board– CARB). The fault has no effect on the use of the vehicle by the customer.
B3401252025-04-03. Service campaign. SERVICE BRAKES. The parking brake actuator cannot be activated or deactivated due to a failed weld. Check Control message “Parking brake failed. When parking, secure the vehicle against rolling away. Mustbe checked by the Service Partner.” The vehicle is still held by the unaffected side and the transmission lock.
B3202252025-03-11. Service campaign. STEERING. Parts of the steering shaft universal joint may have been joined together without having beengreased. As a result, there can be audible squeaking and cracking noises. In some cases, moresteering force is required.
B3401252025-03-03. Service campaign. SERVICE BRAKES. DELIVERY STOP: EMF ACTUATOR
B3202252025-03-03. Service campaign. STEERING. DELIVERY STOP: STEERING SHAFT UNIVERSAL JOINT
B5104252025-02-10. Service campaign. STRUCTURE:BODY. Due to changes in the opening mechanism ofthe trunk/tailgate latch, it is possible that thetrunk/tailgate may not completely lock afterclosing it.
