Mercedes-Benz CLS Brake Light Switch Replacement Parts

The CLS has had two main generations: the first-generation C219 ran from 2004 to 2010, and the second-generation C218 ran from 2011 to 2018, with a facelift around 2014. The brake light switch is a mechanical pedal-box component that differs between these generations, so always buy to match your generation rather than just the year. Confirm your generation with the breaker against your registration to be sure.

These sit in different generations — the 2009 is a C219 and the 2012 is a C218 — so the brake light switches are unlikely to be directly interchangeable due to differences in the pedal box and electrical connectors. You should not assume a cross-generation swap will work even if the switches look similar. Always confirm fitment with the breaker against both registrations before buying.

For a brake light switch, engine size does not typically affect fitment — the switch operates on the brake pedal mechanism rather than on any drivetrain-specific component. A 2.1-litre diesel CLS and a 5.5-litre V8 petrol CLS of the same generation should use the same switch. Confirm with the breaker against your registration to be certain there are no variant-specific differences.

Trim level does not affect brake light switch fitment on the CLS — this is a mechanical switch mounted at the brake pedal and is not tied to interior or exterior specification. Whether your car is a standard CLS or an AMG-badged variant, the switch itself is determined by generation and pedal box, not trim. Do note that AMG models may have slightly different pedal assemblies, so confirm with the breaker if you have an AMG.

The C218 facelift arrived around 2014, and while the pedal box design is broadly similar across the C218 generation, minor running changes mean there is a possibility of differences in the switch connector or fitment arrangement. Name the boundary confidently — pre-2014 and post-2014 C218 — but whether the switch crosses that boundary safely is something you should confirm with the breaker against your specific registration. Do not assume interchangeability across the facelift without checking.

The CLS Shooting Brake was offered as a five-door estate variant of the C218 generation from around 2012 to 2018, sharing the same platform and pedal box as the coupe. In most cases the brake light switch should be the same part, as the body style does not alter the pedal assembly. Confirm with the breaker against both registrations to rule out any minor production differences.
