Mercedes-Benz EQS Transfer Box Replacement Parts

No — the Mercedes-Benz EQS is a fully electric vehicle and does not have a transfer box on any variant. Transfer boxes are mechanical components found in combustion-engined four-wheel-drive vehicles to split drive between axles via a conventional drivetrain; the EQS uses electric motors on each axle with no mechanical link between them requiring a transfer box. If your EQS has a drive or traction fault, the components to investigate are likely the electric motors, power electronics, or the rear/front axle drive units rather than a transfer box.

It is not correct — the EQS 450+ is a rear-wheel-drive electric vehicle and has no transfer box whatsoever. The confusion may arise because some garages apply generic four-wheel-drive terminology to electric vehicles, but the EQS drivetrain is entirely different in layout. What you may actually need is a drive unit (motor and reduction gear assembly) for the relevant axle, so it is worth clarifying exactly which component the garage has identified as faulty.

No — despite having four-wheel drive, the EQS 580 4MATIC does not use a transfer box. Its 4MATIC system drives both axles via separate electric motors, each with its own reduction gearbox, so there is no mechanical transfer box splitting drive from a single source. If you need a drive-related component for this vehicle, speak to a breaker about the specific front or rear drive unit assembly rather than a transfer box.

No transfer box from any other Mercedes-Benz model will fit the EQS because the EQS simply does not have a transfer box at all — there is no mounting point, input shaft, or driveline connection designed to accept one. The EQS electric architecture is fundamentally different from combustion-engined models like the GLE or G-Class where transfer boxes do exist. If you are looking for a used drivetrain component for your EQS, contact a breaker specialising in electric vehicles and describe the specific drive unit or axle assembly you need.

Depending on the fault, the parts most likely to be relevant are the front drive unit, the rear drive unit, or associated power electronics — these are the EQS equivalents of what a transfer box does on a conventional 4WD vehicle. Because electric drive units can involve ECU pairing and immobiliser coding, you should confirm with the breaker against your exact registration whether a used unit will require coding before it can be used. Supplying your VIN or registration to the breaker will help them identify the correct drive unit variant for your specific model year and power output.
