BMW M8 Fuse Box Replacement Parts

Yes, the BMW M8 has fuse boxes — typically one in the engine bay and one in the passenger compartment — as with all modern vehicles. The M8 (F91/F92/F93) was produced from 2019 onwards and all variants, whether Coupe, Convertible, or Gran Coupe, and including the Competition models, carry fuse boxes as standard. If you are sourcing a used unit from a breaker, make sure to specify which fuse box you need (engine bay or interior) as they are different parts.

The BMW M8 (F92 Coupe, F91 Convertible, F93 Gran Coupe) ran as a single generation from 2019 with no major facelift that is known to have significantly changed the fuse box architecture, so there is a reasonable chance of compatibility across those years. That said, minor mid-life electrical updates can affect fuse box design or connectors, so you should confirm with the breaker that the part number from their donor vehicle matches what your registration requires. Never assume fitment purely on year alone.

Trim level — including Competition specification — does not typically affect the fuse box, as the underlying electrical architecture on the M8 and M8 Competition is the same platform. Both use the same 4.4-litre twin-turbocharged V8, so there is no engine-layout reason for a different fuse box either. You may find minor differences in fused circuits if one car has optional equipment the other does not, so confirm the part number with the breaker against your exact registration to be sure.

All three body styles — F92 Coupe, F91 Convertible, and F93 Gran Coupe — share the same basic electrical architecture and engine, so the main fuse box design is likely similar or identical across variants. However, the Convertible and Gran Coupe may have additional circuits for their specific features (roof mechanism, rear passenger electrics), which could mean subtle differences in the fuse box layout or a secondary fuse carrier. Always quote your exact registration to the breaker so they can cross-reference part numbers before agreeing a sale.

On the BMW M8, there is typically a main fuse and relay box in the engine bay, usually near the battery on the passenger-side (NS) of the vehicle, and a secondary fuse box inside the cabin, commonly in the footwell area. There may also be a fuse carrier near the boot-mounted battery, as the M8 uses a rear-mounted or supplementary battery setup. When ordering from a breaker, clarify exactly which unit you need, as each location is a separate part and prices will vary.

The standard 8 Series (G15 Coupe, G14 Convertible, G16 Gran Coupe) shares its platform with the M8 but carries different engines and a different level of electrical complexity, so the fuse boxes are unlikely to be a straightforward swap. The M8's higher-output powertrain and additional performance systems may require different fusing or relay configurations compared to a non-M 840i or 840d. This is one to route directly to the breaker, who can compare part numbers from both donor vehicles against your registration before you commit.
