## 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.
- [B840525](/bulletins/11022119.md), 2025-08-24, Service bulletin: ELECTRICAL SYSTEM. SITUATION After the telematics module \(TCB4\) has been replaced, the replacement part control unit is not accepted byISTA.
- [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.
- [B610325](/bulletins/11015537.md), 2025-03-11, Service bulletin: ELECTRICAL SYSTEM. This is an informational bulletin regarding Plug \& Charge function complaint diagnosis. Possible customer complaints: Plug \& Charge menu does not appear in the vehicle, function not available Problems with the configuration, for example: Contracts cannot be installed Fault / problems when attempting charging with Plug \& Charge Plug \& Charge contract disappeared Plug \& Charge payment method expired
- [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.
- [B520224](/bulletins/11006734.md), 2024-09-01, Service bulletin: ELECTRICAL SYSTEM. Customer states they started to receive Check Control messages for the driver’s seat at the end of eachdriving cycle: One or more of the following check control messages \(CCM\) were present at that time: CCM 434 Seat calibration required. CCM 108 Driver restraint system. Eventually multiple restarts after they first noticed the CCM the seat stopped functioning, the air bag warninglamp illuminated in the instrument cluster, and they received a new Check Control message: CCM 97 Restraint system. There are now 6 DTC faults stored: ACSM6 Air Bag module 930D86 \- Function restraint system driver restricted. C95432 \- seat module Driver \(seat memory\), message status backrest locking standardization required. C95434 \- seat module Driver \(seat memory\), message status backrest locking standardizationrecommended.
