Used Mercedes-Benz Citan Brake Light Switch

Yes, the brake light switch is a standard fitment on all Mercedes-Benz Citan variants — it sits on the brake pedal bracket under the dashboard and tells the brake lights to illuminate when you press the pedal. It is not engine-specific or drivetrain-specific, so every petrol and diesel Citan across all generations has one. When sourcing a used one from a breaker, the generation and engine size are the key details to have ready.

The first-generation Citan ran from 2012 to 2021 and the second generation launched in 2021 on a new platform, so these are quite different vans mechanically. The brake pedal assembly and switch design are unlikely to be identical across that generational boundary, so you should not assume a straight swap. Confirm the part against your exact registration with the breaker before purchasing.

Trim level and body style do not affect brake light switch fitment — whether your Citan is a basic panel van, a Tourer, or a crew-cab derivative, the brake pedal switch is the same within a generation. You may encounter different interior finishes on donor vehicles from a breaker, but that has no bearing on the switch itself. Stick to matching the generation and confirm with the breaker against your registration.

For a brake light switch, engine size is not a significant fitment factor — unlike brake calipers or discs where larger engines can carry heavier braking hardware, the pedal-mounted brake light switch is a simple electrical component that does not vary with engine output on the Citan. That said, it is still worth giving the breaker your full registration so they can confirm the exact connector type and part number matches your van.

Both a 2013 and a 2017 Citan fall within the first generation (2012–2021), so there is a reasonable chance the switch will be compatible, but minor mid-production running changes can affect connector design or mounting. Give both the donor vehicle's registration and your own to the breaker so they can cross-reference part numbers and confirm fitment before the part leaves the yard.

Give the breaker your full registration number, which lets them confirm the generation, engine variant, and any production-run changes relevant to your specific van. It is also worth mentioning the payload or GVW rating shown on the plate inside the driver's door, as vans built to different weight ratings can occasionally carry slightly different components. Having this information ready will help the breaker match the part accurately and avoid a wasted journey or return.
