Mercedes-Benz EQC Differential Replacement Parts

The Mercedes-Benz EQC was produced as a single generation running from 2019 onwards, so there is no major generational boundary to navigate in the way you might find with petrol or diesel Mercedes models. Because the EQC is a pure electric vehicle with a fixed-ratio reduction gear rather than a traditional multi-ratio gearbox, the drive unit and differential arrangement is closely tied to the specific motor and inverter configuration of your car — confirm the exact part compatibility with the breaker against your registration before buying.

The EQC 400 4MATIC and EQC 300 4MATIC use different motor outputs and torque distributions between their front and rear axles, so the differential and drive unit assembly from one variant may not be a straightforward swap to the other. Treat the motor configuration — which you can confirm via a VIN check — as the equivalent of an engine code here, because that is the primary driver of which differential belongs to which car. Always confirm interchangeability with the breaker against your exact registration before purchasing.

AMG Line is a cosmetic and equipment package on the EQC, not a mechanical specification, so it does not alter the differential or drive unit fitted to the car. What actually determines which differential you need is the powertrain variant — 400 4MATIC or 300 4MATIC — and your vehicle's VIN, not whether the car has AMG Line styling or standard trim. You should expect cosmetic differences such as different bumpers or wheels between trim levels, but the drivetrain components themselves are unaffected by trim.

Mercedes made detail changes to the EQC during its production run, and it is not always publicly documented exactly when specific mechanical or mounting specifications were revised on the production line. Name the boundary confidently if you can confirm it via your V5 or a VIN check, and supply that detail to the breaker so they can cross-reference against the donor vehicle. Whether a differential from a pre-update car crosses that boundary safely is something you must confirm with the breaker against your registration rather than assume.

On an electric vehicle like the EQC, the integration between the drive unit, inverter, and the car's control systems is more complex than on a conventional combustion-engined car, and there is a real possibility that components may require coding or configuration after fitting. Whether the differential or drive unit assembly from a donor car needs any ECU pairing or re-coding on your vehicle is something you must confirm with the breaker and your fitting workshop before purchasing a used part. Do not assume a used unit will be plug-and-play without checking this point.

Give the breaker your full registration number and, ideally, your VIN, which will allow them to confirm the exact powertrain variant — 400 4MATIC or 300 4MATIC — and any mid-production specification changes that apply to your car. Specifying which axle the differential is from (front or rear) is also important on a 4MATIC car, as the front and rear units are not the same. Trim level and colour are irrelevant to fitment, so focus on the mechanical specification rather than the cosmetic details of your car.
