Mercedes-Benz EQC Fuse Box Replacement Parts

Yes, the EQC does have fuse boxes — typically a main underbonnet fuse box and a secondary interior fuse box covering low-voltage circuits such as lighting, infotainment, and ancillaries. However, because the EQC is a fully electric vehicle, it does not have a conventional engine-bay fuse box associated with a combustion engine or fuel system; the high-voltage battery system has its own separate safety components. When searching for a used fuse box, make sure you and the breaker are clear about which fuse box location you need — underbonnet low-voltage, interior, or high-voltage battery management — as these are distinct parts.

The Mercedes-Benz EQC (X293) was sold in the UK from 2019 onwards as a single generation with no major mid-life platform change, so year-to-year variation is relatively limited. That said, Mercedes did introduce running changes and software-related updates during the production run, which can affect fuse box configuration and connector layouts. Confirm the exact year and build date of the donor vehicle with the breaker against your registration to be sure the unit matches.

Trim level — whether Sport, AMG Line, Edition 1, or any other EQC variant — does not in itself determine fuse box fitment, as the underlying electrical architecture is shared across trims on the same platform. What can vary is whether optional equipment such as a panoramic roof, advanced driver aids, or premium sound systems adds additional fused circuits, so a car with fewer options may have a slightly different fuse box configuration than a fully loaded example. Ask the breaker to check the donor car's specification against yours to rule out any option-related differences.

The EQC's fuse box location and wiring loom layout can differ between left-hand-drive and right-hand-drive vehicles, particularly for the interior fusebox which may be mounted on the opposite side of the dashboard. UK-specification right-hand-drive cars are far safer to match to another RHD donor vehicle. Confirm the hand-of-drive of the breaker's donor car before proceeding.

No — the high-voltage battery management system on the EQC is a separate and highly specialised assembly, distinct from the conventional low-voltage fuse boxes that cover everyday electrics. Sourcing or replacing high-voltage components on an electric vehicle requires specialist knowledge and equipment, and should not be treated as a straightforward used-parts swap. Speak to a Mercedes-specialist EV workshop or main dealer before approaching a breaker for anything related to the high-voltage system.

Give the breaker your full registration number so they can cross-reference the donor car's build date, specification, and options against your vehicle — this is the most reliable way to check compatibility. The EQC's fuse box is closely tied to the car's software and BCM (body control module), so a like-for-like match on year, spec, and optional equipment is important. Never guarantee fitment based on model name alone, and ask the breaker whether the unit will need coding or programming before use.
