Second Hand Mercedes-Benz EQC Engine

The EQC is a fully electric vehicle, so it has no combustion engine — the drive unit consists of two electric motors (one per axle on the 400 4MATIC, the only variant sold in the UK) rather than a traditional petrol or diesel engine. When contacting a breaker, give them your full registration number so they can run a VIN check, and confirm the motor/drive unit part numbers from your V5 or a dealer printout. This is the single most useful information you can supply, as the EQC's drive components are matched closely to the vehicle's architecture.

In the UK, Mercedes-Benz sold the EQC exclusively as the 400 4MATIC, producing around 408 hp via its twin-motor setup, so there is no multi-variant engine fitment question in the way there would be with a combustion-engined car. Because only one drivetrain configuration was offered here, a drive unit from another UK-market EQC is likely to be the correct specification, but you should still confirm the exact part numbers with the breaker against your registration before purchasing. Never assume fitment without that check.

The Mercedes-Benz EQC was produced as a single generation (no separate facelift generation was introduced in the UK market during its production run from 2019 onwards), so year-to-year differences are less dramatic than on a model with a defined mid-life facelift. That said, Mercedes does make running production changes to electric drivetrains and associated electronics, and ECU pairing and immobiliser coding to the vehicle must be confirmed with the breaker against your specific registration rather than assumed to be straightforward. Treat any cross-year swap as requiring professional verification.

No, trim level does not affect the drive unit itself — Sport, AMG Line, and Edition 1 are specification packages covering interior and exterior features, not mechanical drivetrain differences. The EQC's motors and drive unit are the same across these trim variants, so a drive unit from an AMG Line car is mechanically the same as one from a Sport. You may find cosmetic or ancillary differences between trim levels when stripping the donor car, but these have no bearing on drive unit fitment.

Because the EQC is fully electric, there is no traditional gearbox to match — the drive unit incorporates single-speed reduction gears as an integral part of the motor assembly, so there is no separate gearbox selection to make in the way you would have with a combustion car. What you should confirm with the breaker is that all ancillary components (inverters, cooling connections, mounting hardware) match your vehicle's specification, as these can have running changes mid-production that are best verified against your registration. Always cross-reference part numbers before buying.

ECU pairing and immobiliser coding for an electric drive unit is a topic you must confirm with the breaker against your specific registration, as this falls outside what can be stated as fact in a general fitment guide. Electric vehicles commonly require control unit programming after a drive unit replacement, and this typically needs Mercedes-Benz dealer-level diagnostic equipment or a specialist with appropriate software. Ask the breaker explicitly whether the unit they supply has been cleared of previous vehicle pairing, and budget for professional coding as part of the job.
