Second Hand Mercedes-Benz EQE Body Control Module

The EQE is a fully electric vehicle built on Mercedes-Benz's dedicated EVA2 platform, and like all modern Mercedes models it does have a central gateway and various domain control units managing body functions — however, what Mercedes-Benz calls the central architecture on the EQE differs significantly from a traditional Body Control Module (BCM) found on older or combustion-engine vehicles, with functions distributed across multiple networked control units rather than a single BCM. If you've been quoted a 'Body Control Module' for your EQE, it's worth confirming with the breaker exactly which specific control unit is needed — it may be the Central Gateway (CGW), the SAM (Signal Acquisition Module), or another domain controller. Provide your registration to the breaker so they can identify the precise unit your car requires.

The Mercedes-Benz EQE (V295 saloon) launched in the UK in 2022, with a facelift introduced for the 2024 model year — this facelift brought software and hardware revisions that may affect whether control units are directly interchangeable across that boundary. Both pre-facelift (2022–2023) and post-facelift (2024-on) cars share the same V295 platform, but given how tightly integrated the EQE's control units are with its over-the-air software ecosystem, whether a specific unit crosses that facelift boundary is something you must confirm with the breaker against your registration. Never assume compatibility without that check.

The EQE was offered in the UK in trim levels including EQE 300, EQE 350, EQE 350+ (4MATIC) and AMG EQE 43 and 53 variants, and while trim level generally does not affect fitment of core body control electronics, the AMG variants and 4MATIC all-wheel-drive versions carry additional control units for their drive systems that standard rear-wheel-drive models do not have. For the main body/gateway control functions, trim is unlikely to be the deciding factor, but drivetrain (RWD versus AWD) and specification level (standard versus AMG) may influence which exact unit is fitted. Confirm the precise part number with the breaker against your registration to be sure.

The EQE and EQS share the same EVA2 electric platform and some components do interchange between them, which might suggest a control unit could cross over — however, the two cars differ in size, specification, and software calibration, and any cross-model compatibility for a central control unit is not something that can be stated confidently here. Route this question directly to the breaker, providing both registrations, so they can compare part numbers before you buy. Do not assume platform sharing alone guarantees interchangeability for an electronic unit.

Yes — on the Mercedes-Benz EQE, any replacement central gateway, SAM, or domain control unit will almost certainly require programming or coding to the vehicle using Mercedes-Benz diagnostic equipment (XENTRY) before it functions correctly, as these units communicate over the car's high-speed CAN and Ethernet networks and are tied to the vehicle's VIN and software environment. A used unit from a breaker will typically carry the previous vehicle's coding, so fitting alone is not sufficient. Factor in the cost of coding by a Mercedes-Benz specialist or a suitably equipped independent when budgeting for this repair.
