## Other bulletins for the same vehicles and component

- [B110426](/bulletins/11035500.md), 2026-08-03, Service bulletin: ENGINE; ELECTRICAL SYSTEM. The manual starting of electronic engine oil level measurement from inside the vehicle, usually afterperforming an engine oil service task, is inoperative or it may lock up at between a 15% to 30% completionrate.
- [B840226](/bulletins/11035408.md), 2026-07-31, Service campaign: ELECTRICAL SYSTEM. Once the Telematics Module \(TCB2\) enters sleep mode, a BMW Data Services trigger for Remote Services\(remote engine start, lock/unlock/climate conditioning\) will not be able to reactivate the TCB2. Due to this issue, Remote Services will not function in the vehicle when parked and locked.
- [B120626](/bulletins/11034450.md), 2026-07-03, Service campaign: ELECTRICAL SYSTEM. In these vehicles with an S68 engine, an incorrect diagnosis of the Valvetronic \(VVT\) may occur. Undercertain operating conditions, the software may detect a short\-circuit in the valve control system even thoughthere is no fault. When the above\-mentioned fault occurs, the red Check Control warning light ‘Drive system fault’ illuminates.This can result in the intake valves closing gradually, which may lead to misfires while the engine is running.
- [B652025](/bulletins/11032744.md), 2026-05-18, Service bulletin: ELECTRICAL SYSTEM. After replacing the Multifunctional Display \(MFD\), the Central Information Display \(CID\) is black. The backlight of the CID is illuminated, and touch function does register an audible sound.
- [B120326](/bulletins/11030061.md), 2026-03-13, Emissions: ELECTRICAL SYSTEM. BMW AG is conducting Voluntary Emissions Recall \(effective March 11, 2026\) on certain Model Year 2023 \-2026 BMW vehicles that were produced between January 14, 2022, and September 16, 2025.
- [InVeh\-InApp\-Comm](/bulletins/11029008.md), 2026-02-25, Over\-the\-air update: EXTERIOR LIGHTING. Residues from the production process may be present on the Frontal Light Electronics circuit board. This could result in the failure of a lighting function \(e.g. daytime driving lights, low\-beam headlight, turn indicators\) on the affected side in the front area. In the event of a fault, you will be informed by a Check Control message. The front light module will be replaced.
- [B720125](/bulletins/11028928.md), 2026-02-23, Warranty extension: AIR BAGS; ELECTRICAL SYSTEM; SEATS. A situation may occur where the front passenger seat is not occupied; however, a “fasten seat belt” warning and a front passenger seat air bag deactivation message appears. If the situation is currently present, sit in the seat and move the seat to a slightly different position. The POL \(Passenger Occupancy Light\) light should now function correctly. In some cases, the Air bag Warning Light was illuminated, and the following Advanced Crash Safety Module \(ACSM\) fault is stored: 930A1C \- Front passenger seat occupancy detection transmitting fault \(moisture\)
