Used Mercedes-Benz EQB Transfer Box

No — the EQB is a fully electric vehicle and does not have a transfer box. On the EQB 350 4MATIC (the four-wheel-drive variant), the rear wheels are driven by a separate electric motor rather than by a mechanical transfer box splitting drive from a combustion engine, so the part simply does not exist on this model. If you are looking for a drivetrain component, you may actually need one of the electric drive units (front or rear motor/gearbox assembly), and a breaker will be able to advise which unit applies to your specific variant.

The EQB 4MATIC does not use a transfer box at all; its all-wheel drive is achieved by having two independent electric motors — one on each axle — with no mechanical transfer case linking them. The component you may be thinking of is the rear electric drive unit or the front drive unit, depending on which axle has developed a fault. Describing the fault symptoms to a breaker, along with your registration, will help them identify the correct electric motor or drive unit assembly you actually need.

No transfer box will fit an EQB because the EQB has no provision for one — it is a purpose-built electric vehicle with no combustion drivetrain and no mechanical four-wheel-drive system to connect. Attempting to source a transfer box for this vehicle suggests there may be a misidentification of the faulty part; the correct starting point is to confirm with a breaker or Mercedes technician exactly which electric drive component has failed. Your registration or VIN will allow a breaker to look up the correct motor or drive unit part number for your specific EQB variant.

Yes, the production year can matter for electric drive unit compatibility, as the EQB (X243) launched in 2021 and may have seen hardware or software revisions across its production run. However, because the EQB has no transfer box, the relevant parts to compare year-to-year would be the front or rear electric motor assemblies, not a transfer box. Always confirm the exact part against your registration with the breaker, particularly for components that may involve ECU pairing or motor control unit matching.

No trim level of the EQB — whether EQB 250, EQB 300 4MATIC, or EQB 350 4MATIC — was ever fitted with a transfer box, so trim is irrelevant here. The difference between trim levels that matters mechanically is whether the car is a single-motor (front-wheel drive) or dual-motor (4MATIC) variant, and even the 4MATIC versions use two separate electric motors rather than a transfer case. If you are searching for a drivetrain part, confirm the motor configuration of your specific car with a breaker using your registration.
