## Other bulletins for the same vehicles and component

- [B611626](/bulletins/11036456.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/11022361.md), 2025-09-03, Service campaign: ELECTRICAL SYSTEM. A faulty electric auxiliary heater may have been installed in the certain vehicles. This could result in the failure of the electric auxiliary heater, utilized for the vehicle interior.
- [B651825](/bulletins/11021819.md), 2025-08-13, Service bulletin: ELECTRICAL SYSTEM. When the alarm system is activated and doors are locked, within a short period the doors will unlock, and a “double beep” acoustic confirmation is heard from vehicle.
- [B120523](/bulletins/11012080.md), 2024-12-31, Service bulletin: ELECTRICAL SYSTEM. The customer states there is a Drivetrain Malfunction message displayed in the instrument cluster. In addition, the following fault memory entries are saved in the CCU \(Combined Charging Unit\) 0317F2 \- High\-voltage system, insulation fault detected: when switch contactors are closed. 0317F1 \- High\-voltage system, insulation resistance below warning threshold: when switch contactors are closed. The fault memory entries \(isolation faults\) can occur both individually and in combination and must be traced back to the eDrive motor based on the ISTA test procedure. If ISTA test procedure lists possible cause of fault as; A metal chip is found behind the brush module \(between the brush module and the end shield of the electrical machine\). Repair required. Refer to service solution no. 20000794435083 in Aftersales Information Research \(AIR\). Follow information in the Procedure section below.
- [B612124](/bulletins/11008117.md), 2024-09-29, Service bulletin: ELECTRICAL SYSTEM. The \(CCM\) Check Control message: “811 – Stop carefully. Hood open”, is displayed even though the hood is closed. Fault code 80415B “Engine compartment lid contact switch: Line fault or faulty” is often stored inthe BCP module.
- [B651124](/bulletins/11002658.md), 2024-07-01, Service campaign: ELECTRICAL SYSTEM. Quality improvements and robustness measures are to be implemented on the affected vehicles via thissoftware update. The software update improves functions in the following areas of the vehicle: Bluetooth malfunctions The start\-up phase of the HU has been shortened \(faster start of the operating system\) The number of disconnections from Apple CarPlay have been reduced Vehicle access and the drive\-ready state have been improved The AC charging abort error has been fixed Remote Control Parking without function
- [B840224](/bulletins/11000566.md), 2024-05-30, Service bulletin: ELECTRICAL SYSTEM. The Check Control Message “Emergency call not available” is displayed to the customer. Check Control Message 299 is stored in the Instrument Cluster check control message list or in the vehiclekey data. This fault may be intermittent and can heal itself after a drive cycle. It may no longer be displayed to the customer in the next life cycle.
