Second Hand Mercedes-Benz CLS Ignition Switch

The CLS (both the W219 generation from 2004–2010 and the W218 generation from 2011–2018) does use an ignition switch, though the design varies by generation — earlier cars use a more traditional barrel-type ignition switch while later models moved toward a keyless ignition button system. When searching for a used part, it is important to know which type your car has, as the two are not interchangeable. Confirm the exact system fitted to your car with a breaker against your registration before ordering.

Both years fall within the first-generation CLS, the W219 (2004–2010), so there is a reasonable chance the ignition switch will be compatible. However, Mercedes did make running changes during production, and whether a specific switch from a 2006 car crosses over cleanly to a 2009 car is best confirmed with the breaker against both registrations before you commit.

The W219 (2004–2010) and the W218 (2011–2018) are separate generations with different architectures, and the ignition systems are not the same — the W218 moved to a more integrated keyless start setup on many variants. These parts are not directly interchangeable, so you should source a switch specific to your generation and confirm the exact part reference with the breaker against your registration.

Trim level and engine choice do not affect the ignition switch itself — the switch is determined by the generation (W219 or W218) and the ignition system type fitted to your car, not by whether you have a standard or AMG variant. You may find cosmetic differences such as a different surround or trim ring depending on the interior spec, but the functional switch component should be the same within a generation. Confirm the exact part against your registration with the breaker to be sure.

The W218 CLS received a facelift in 2014, which brought updates to lighting, styling, and some interior elements, but the core ignition system was not significantly changed at this point. That said, whether a pre-facelift (2011–2014) switch will plug straight into a post-facelift (2014–2018) car without any difference is something you should confirm with the breaker against your specific registration, as connector or software differences can sometimes be a factor on Mercedes parts.

Findapart connects you with UK vehicle dismantlers (breakers) who can supply used Mercedes CLS ignition switches from salvaged cars. When requesting a quote, give the breaker your full registration so they can match the correct generation and ignition system type to your car, as supplying the wrong type is a common issue with this part. A reputable breaker should be able to check the part number against their stock before despatch.
