This is to notify you of the Service Campaign Launch to update the Battery Management System (BMS) in 394 Model Year (“MY”)
2024 EQB (243 platform) vehicles. The vehicles will be visible and flagged in VMI as “OPEN” on January 10, 2025.

Background

Issue

Mercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined
that on certain MY 2024 EQB (243 platform) vehicles, the BMS software does not
correspond with current production specifications. In this case, a yellow malfunction
warning message could erroneously be triggered and displayed in the instrument
cluster. This warning message presents no impact to the functionality of the vehicle.

What We’re Doing

MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will
update the software of the BMS control unit.

Parts

The remedy is available and can be performed as necessary.
