Service campaign B612025

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.

NHTSA's summary

RSU availability. It is possible the State of Health (SoH) of the high-voltage (HV) battery is displayed incorrectly to the customer. The value is continuously displayed as 100% regardless of the actual ageing of the HV battery.

The document

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Components

Electrical system

Vehicles listed
BMW 550E XDRIVE2025 (the catalog's model; the bulletin names a series or trim of it)
BMW I52025

Listing a model year does not mean every vehicle of it is concerned: the document says which.

A recall listed here may apply to some of the same vehicles. Only the manufacturer can say whether it applies to one vehicle.

Other bulletins for the same vehicles and component
B6118262026-09-28. Service bulletin. Due to unfavorable software, the Storage Management Electronics (SME) will not show fault codes that trigger the Malfunction Indicator Lamp (MIL) when performing ISTA Service Function "Display Permanent SAE Fault Codes." As a result, workshops will have to identify SME-specific permanent SAE (emission related) Diagnostic Trouble Codes (DTCs) stored in the vehicle during diagnosis or when preparing a vehicle for a State Emission Inspection and Maintenance through a workaround procedure.
B6409252026-08-27. Service campaign. A faulty electric auxiliary heater may have been installed in the certain vehicles. This could result in thefailure of the electric auxiliary heater, utilized for the vehicle interior.
B6106262026-07-03. Service bulletin. 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.
B6103262026-03-13. Service bulletin. Several complaints are possible: Vehicle does not start Gear cannot be engaged Various Check Control Messages Malfunction indicator lamp (MIL) on Several Check Control messages are possible: “It is possible to continue driving. High-voltage system.” “You can continue driving. Drivetrain.” “Restart not possible. Drivetrain fault.” “Call Roadside Assistance. Drivetrain failure.” “Information: Total error of vehicle.” The following fault memory entries are stored in the CCU: D796D9 - Message (- 0x91) not up-to-date, receiver CCU, transmitter EME D796DC - No message (- 0x91), receiver CCU, transmitter EME D796D8 - No message (- 0x91), receiver CCU, transmitter EME Other fault codes below may be stored in the EGS BA09B8 – Inverter, Voltage Sensor, 5V HV AUX: Out of range or open connection detected BA0A45 – ECU internal: Internal error of the synchronous serial data bus. Additional fault memory entries are possible. Similar fault memory entries indicating a missing EMEmessage (Traction E-Machine Electronic) can also be stored in other control units.
B6119252026-03-13. Service bulletin. The malfunction indicator lamp (MIL) is triggered by the erroneous fault code 031BFC- AC charging,charging electronics 2, internal fault: No internal capacitor discharge stored in the CCU. However, AC charging is operating as designed without a charging concern or issue. Affected PHEV vehicles have the CCU-03 (7.4 kW / 11 kW) with I-levels from …24-07-500 to …25-11-5xx.
B6122252026-03-13. Service bulletin. Malfunction indicator lamp (MIL) is triggered by the erroneous fault code(s) BA0023 - Control unit: internalfault (software group fault) In addition, the BA0008 - CCU, internal coolant temperature sensor:Signal implausible faults may be stored in the CCU memory. However, AC charging is still operating as designed, without any related drivability complaints. Affected PHEV vehicles have the CCU-03 (7.4 kW / 11 kW) with I-levels from 24-07-500 to 25-11-5xx.
B6123252026-03-13. Service bulletin. The malfunction indicator lamp (MIL) is triggered and 0318E2 AC charging, charging electronics 1,component protection: Overload current on AC side fault may be stored during AC charging Level 1(120 VAC). Note: Despite the fault memory entry (and the malfunction indicator lamp), the AC charging process willcontinue operating as designed and there is no related drivability complaint. Affected PHEV (plug-in hybrid electric vehicle) vehicles with CCU-03 (7.4 kW combined charging unit).
