# Service bulletin B840822

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.

- Type: Service bulletin
- NHTSA id: 10235205
- Published by NHTSA: 2023\-05\-01
- Manufacturer's number: B840822
- Manufacturer's date: 2023\-03\-01
- NHTSA component: EQUIPMENT; ELECTRICAL SYSTEM

## NHTSA's summary

The 3G network in the US has been shut down. This means that only the 4G network will be available. In the 4G network, voice calls will be transferred via the Voice over LTE \(VoLTE\) function. For this purpose, the SIM card must perform an IMS registration in the mobile communication network. Due to a production error, the telematics control units were delivered without an IMS configuration. The Connected Drive voice services \(Concierge Call, BMW Assistance, and emergency call voice\) can no longer be used regionally in the US in vehicle with telematics control units ATM\-1 and TCB\-4G. Voice control of the vehicle and all other telephone \(paired mobile devices\) functions are not affected. Emergency call location data is unaffected.

## 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.
