Fitment on a used fuse box varies by vehicle, so a bit of detail goes a long way. Our request form covers what breakers need to know, so every quote you get back is for the correct part:
The CLK ran across two main generations: the W208 (1997–2002) and the W209 (2003–2009), and these are fundamentally different platforms with different electrical architectures, so a fuse box from the W208 is very unlikely to be compatible with a W209 and vice versa. Within the W208 generation you stand a much better chance of a used unit fitting, and the same applies within the W209 generation. Always confirm the exact part number on your existing fuse box with the breaker before buying, as wiring configurations can vary even within a generation.
Engine variant can affect the fuse box on the CLK because different engines have different ancillaries, sensors and relay requirements that are mapped into the fuse and relay layout. A box from a 320 may not share the same configuration as one from a 200 Kompressor, even on the same generation chassis. Give your registration to the breaker and ask them to match the part number rather than going by engine size alone.
Trim level on the CLK (Avantgarde, Elegance, Sport) can actually influence the fuse box because higher or different trims may have additional electrical equipment such as memory seats, upgraded audio or different lighting systems that need corresponding fuse and relay positions. Unlike purely mechanical parts where trim rarely matters, electrical distribution components like fuse boxes can differ between spec levels. Confirm the exact part number from your existing unit with the breaker to make sure you get a box that matches your car's equipment level.
The CLK typically has more than one fuse and relay location: there is usually a main fuse box in the engine bay on the driver's side (NS in right-hand-drive UK cars), and a further fuse and relay panel inside the cabin, often in the footwell area or behind a trim panel. When ordering a used unit, make sure you and the breaker are clear on which location you need, as they are separate components and not interchangeable with each other.
Both fall within the W209 generation (2003–2009), which is a good starting point, but there were running production changes and option-dependent wiring differences throughout that period that could affect relay and fuse layouts. The safest approach is to read the part number off your existing fuse box and ask the breaker to match it exactly, rather than relying on year alone. A good breaker will cross-reference against your registration to check compatibility before supplying the part.
Mercedes-Benz did share platforms and some electrical components across the W203 C-Class and W211 E-Class ranges that were contemporary with the W209 CLK, and some fuse box components may be related, but differences in body style, equipment levels and option packs mean you cannot assume direct interchangeability. Some breakers with experience of Mercedes parts will know which units cross over, so it is worth asking them directly with your CLK's registration to hand rather than assuming a match.
