Mercedes-Benz EQS Fuse Box Replacement Parts

Yes, the EQS does have fuse boxes — despite being a fully electric vehicle, it still uses fuse boxes to protect its 12V auxiliary circuits, comfort systems, and high-voltage control electronics. You won't find a traditional engine-bay fuse box in the same sense as a petrol or diesel car, but there are multiple fuse and relay units located in the cabin and luggage areas. When sourcing from a breaker, it's worth specifying exactly which fuse box location you need, as there are several on the EQS.

The Mercedes-Benz EQS (V297 generation) launched in 2021 and covers the 2022–2024 model years within the same foundational platform, so a fuse box from a 2022 car is likely to be directly relevant to a 2023 or 2024 car. That said, Mercedes did introduce running production changes during this period, and the specific fuse box variant can differ depending on the powertrain spec (EQS 450+, 450 4MATIC, 580 4MATIC, etc.). Always confirm the part number from the breaker against your exact registration before purchasing.

It can matter, because the 450+ (single motor, rear-wheel drive) and the 580 4MATIC (dual motor, all-wheel drive) have different high-voltage and control architectures, which can mean different fuse box configurations or different part numbers. The 12V auxiliary fuse boxes may be more interchangeable across variants than the powertrain-related units, but this isn't something that should be assumed. Give the breaker your full registration so they can verify the correct part against the specific powertrain configuration of your car.

Trim level — whether your EQS is AMG Line, Executive, or another specification — does not fundamentally affect which fuse box you need, as the electrical protection architecture is determined by the car's underlying build rather than its trim designation. However, certain optional equipment packages fitted to higher trims (such as rear-axle steering, advanced MBUX Hyperscreen, or massaging seats) may mean additional fuse positions are populated differently. A breaker can cross-reference your registration to confirm the build matches, so trim-level differences aren't a barrier to finding the right part as long as the spec is verified.

The EQS (V297) and EQE (V295) share Mercedes' MEA electric platform and have significant engineering commonality, so some components do interchange between the two models. However, fuse boxes are closely tied to the specific electrical architecture, wiring loom configuration, and feature set of each vehicle, and the EQS is a larger car with more complex systems than the EQE. This is one to route directly to your breaker — give them both registrations and ask them to compare part numbers before committing to the purchase.

The EQS has more than one fuse and relay unit — there is typically a fuse box in the passenger compartment (often accessible near the dashboard or footwell area) and additional units associated with the high-voltage battery management and boot area electronics. Location does affect which part you need, so be as specific as possible when contacting a breaker — describe the symptoms or the location you're working on rather than just asking for 'a fuse box'. Providing your registration and the approximate location of the faulty unit will help the breaker pull the correct part from their dismantled vehicle.
