Second Hand Mercedes-Benz EQB Differential

The Mercedes-Benz EQB (X243) launched in the UK in 2022 and has run as a single generation through to the current model, so a 2022 and a 2024 are within the same generation. That said, Mercedes did introduce running changes during production, so confirm with the breaker against your exact registration that no ancillary or mounting updates affect the specific unit they have. Never assume fitment without that check.

No — these are fundamentally different drivetrains. The EQB 250 is a single-motor front-wheel-drive setup, while the EQB 350 4MATIC uses dual motors with front and rear drive units, so the differentials are not the same parts and will not interchange. Always confirm the motor configuration and drivetrain layout with the breaker against your registration before ordering.

Trim level does not affect differential fitment on the EQB — AMG Line, Sport, and other trim variants are cosmetic and equipment-based distinctions, not mechanical ones. What matters is the drivetrain: whether your car is the 250 (front-wheel drive) or the 350 4MATIC (all-wheel drive) and the associated motor configuration. Confirm the drivetrain specification with the breaker against your registration.

The most reliable way is to supply your registration number or VIN to the breaker, as this identifies the exact motor configuration and drivetrain fitted — this is more useful than the badge alone, since a '350' badge tells you the power output but the breaker needs to match the specific drive unit (front or rear on 4MATIC cars). If you have your V5C, the variant and VIN details there will help the breaker cross-reference the correct part. Always confirm with the breaker rather than assuming a visual match is enough.

This is something you must confirm with the breaker and your fitting garage, as ECU pairing and any immobiliser-related coding requirements vary and we cannot state this as fact for your specific vehicle. A specialist Mercedes-Benz independent or a main dealer will be best placed to advise on whether the replacement unit needs any software work after installation. Do not assume a used differential will be plug-and-play without checking.

Both a 2022 and a 2023 EQB sit within the same X243 generation, so the core specification should be shared, but mid-production ancillary or mounting changes can occur and are difficult to verify without checking part numbers. Give the breaker your registration so they can compare what they have against your car's exact build spec before you commit. This is the safest route and a good breaker will do this check as a matter of course.
