Mercedes-Benz SLK Fuse Box Replacement Parts

Yes, every variant of the Mercedes-Benz SLK has at least one fuse box — typically there is a main fuse box in the engine bay and a secondary one in the interior, often behind a panel in the footwell or dashboard area. The SLK is a two-seater roadster produced across three generations (R170 1996–2004, R171 2004–2011, and R172 2011–2020), and all variants including the four-cylinder, six-cylinder, and AMG models carried fuse boxes as standard. If you are searching for a used unit, make sure to specify which location (engine bay or interior) you need, as breakers will want to know this.

These two cars are from different generations — the 2003 model is R170 and the 2006 model is R171 — and the fuse boxes are unlikely to be compatible as the electrical architecture changed significantly between these generations. Fitment across this boundary is not straightforward, so you should confirm with the breaker against your exact registration before ordering. Stick to sourcing a unit from the same R171 generation (2004–2011) for the most reliable match.

Engine choice can affect fuse box fitment on the SLK because different engines (for example the four-cylinder SLK200, six-cylinder SLK350, or supercharged SLK55 AMG) may have different electrical demands and fusing arrangements, particularly in the engine bay fuse box. Trim level alone — for example Kompressor or AMG Sport badging related to cosmetics rather than drivetrain — is less likely to matter, but engine variant genuinely does, so always give the breaker your full registration rather than just the model name. The interior fuse box is less likely to vary by engine but it is still worth confirming.

These cars span the R171 (2004–2011) and R172 (2011–2020) generation boundary, and the fuse boxes from these two generations are not expected to be a direct swap due to changes in electrical systems between generations. You should source a fuse box from within the correct generation for your car — R172 units for a 2012 onwards car — and confirm the exact part against your registration with the breaker. Do not assume compatibility across this boundary without checking.

No, these are two distinct components with different functions and layouts, so you must make sure you are ordering the correct one for your needs. The engine bay fuse box on the SLK handles higher-current circuits such as the battery, alternator, and major electrical systems, while the interior unit manages cabin electrics like lights and accessories. Always tell the breaker which one you need and describe the fault or location you are trying to address so they can supply the right part.

The R172 received a facelift in 2016, so a 2015 car is pre-facelift and it is worth checking whether any electrical changes accompanied that update before fitting a post-facelift unit. Whether a post-2016 fuse box will interchange with your 2015 car is something you should confirm directly with the breaker against your registration, as minor wiring or circuit changes can affect compatibility. Staying within the pre-facelift R172 period where possible is the safest starting point.
