## Other bulletins for the same vehicles and component

- [B611226](/bulletins/11037844.md), 2026-10-02, Service campaign: ELECTRICAL SYSTEM. The BCP controls several vehicle functions, including the windscreen wipers and air conditioning actuators. Low current flow may cause excessive current in parts of the BCP circuit board and damage the unit. If a fault occurs, the wipers or air flap controls may operate incorrectly or fail. A wiper failure is indicated by a yellow warning light and the “Windscreen wiper fault” Check Control message.
- [B611526](/bulletins/11036455.md), 2026-08-28, Service campaign: ELECTRICAL SYSTEM. In vehicles equipped with the Roof Function Center “FZD‑21” variant, a quiescent‑current violation mayoccur if the system fails to enter sleep mode. When this sleep error is present, a remote software upgrade\(RSU\) may be aborted and the FZD can become degraded. The following Check Control Messages \(CCMs\) may be displayed: “Energy Management — Increased Energy Consumption While Parked.” “Software Upgrade Failed — Workshop Visit Required.”
- [B640825](/bulletins/11036382.md), 2026-08-27, Service campaign: ELECTRICAL SYSTEM. A faulty electric auxiliary heater may have been installed in the certain vehicles. This could result in thefailure of the electric auxiliary heater, utlized for the vehicle interior.
- [B651826](/bulletins/11034469.md), 2026-07-03, Service bulletin: ELECTRICAL SYSTEM. If BMW Intelligent Personal Assistant is active in the vehicle, once the customer exits the vehicle and a newkey cycle starts, the Intelligent Personal Assistant is deactivated and no longer available.
- [B651726](/bulletins/11034468.md), 2026-07-03, Service bulletin: ELECTRICAL SYSTEM. After a factory reset of the head unit, the navigation voice input cannot be activated or deactivated.
- [B651426](/bulletins/11034467.md), 2026-07-03, Service bulletin: ELECTRICAL SYSTEM. The vehicle may experience various operational issues with Apple CarPlay Projected Modes such as: Dropped connections No automatic reconnection Display errors
- [B651226](/bulletins/11034466.md), 2026-07-03, Service bulletin: ELECTRICAL SYSTEM. The voice command to deactivate Automatic Engine Start/Stop function can also trigger the activation ofIconic Sounds.
- [B610626](/bulletins/11034463.md), 2026-07-03, Service bulletin: ELECTRICAL SYSTEM. Charging sessions cannot be started or they are interrupted while using a Level 2 AC high\-power chargingstation, or with a Level 3 DC charging station. Charging may start normally but can interrupt after some time. Level 2 \(240 V\) Flex Charger and Wall boxmay also be affected. The red or white LED is displayed on the high\-voltage charging socket; however, no associated fault codesare stored.
- [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.
- [B120326](/bulletins/11034449.md), 2026-07-03, Warranty extension: ELECTRICAL SYSTEM. Due to an implementation error in various OBD diagnostics in the vehicle's control units, in very rare cases itmay happen that stored fault memory codes \(DTCs\) and the MIL \(warning light\) are not automaticallydeleted even though the underlying malfunction has already been rectified. This does not comply with the statutory OBD specifications.
