Cheap Mercedes-Benz CLS Fuse Box

Yes, every variant of the CLS has at least one fuse box — typically located in the engine bay and/or the interior footwell area — regardless of engine or trim level. The fuse box is a fundamental electrical component fitted to all CLS models across both generations. When sourcing a used unit, the key is matching it to the correct generation and build specification of your car.

No, the W219 and W218 are entirely different platforms with different electrical architectures, so a fuse box from the first generation will not be a straight swap into the second generation. This is a confirmed generational boundary and the parts are not interchangeable. Always source a fuse box from the same generation as your car — confirm the exact part number with the breaker against your registration to be sure.

Engine variant can affect fuse box specification on the CLS, as different engines may require different fusing and relay configurations within the box. Unlike some simpler parts, fuse boxes are closely tied to the electrical system of the specific engine and equipment fitted to your car. Give the breaker your full registration so they can check the part number matches your exact build before buying.

Trim level alone does not typically change the core fuse box, but the optional extras and factory-fitted equipment associated with a particular trim can influence the specification of the fuse box fitted. For example, a car with the AMG Sport pack or additional comfort features may have a fuse box configured differently to a base-spec car of the same engine. Confirm the part number with the breaker against your registration rather than relying on trim name alone.

The W218 CLS received a facelift in 2014, and while both sit within the same generation, changes to electronics or optional equipment around that point can mean the fuse box specification differs. The generational boundary is clear, but whether a specific pre-facelift unit crosses into a post-facelift car without issue is something you should confirm with the breaker against your registration and part number. Do not assume compatibility across the 2014 facelift without checking.

On the CLS, fuse boxes are typically found in the engine bay and in the interior, often in the driver's side footwell or dashboard area — some models have more than one. If you need a specific fuse box (for example the engine bay unit rather than the interior one), make sure you tell the breaker which location you need, as they are different parts. Providing your registration and describing where the fault is will help the breaker supply the correct unit.
