Cheap Mercedes-Benz CLA Horn

The CLA has two main generations: the first-generation C117 (2013–2019, facelifted in 2016) and the second-generation C118 (2019–onwards). Horns are electrically simple components and within the same generation fitment is generally straightforward, but crossing from the C117 to the C118 introduces different mounting points and wiring connectors, so confirm compatibility with the breaker against your registration before buying.

No — the horn is not engine-specific and is fitted across petrol, diesel, and AMG variants of the CLA alike. You do not need to match engine size or fuel type when sourcing a used horn, just focus on the generation of the car.

Both sit within the first-generation C117 (2013–2019), with the facelift arriving in 2016. Horns within this generation are generally interchangeable as the core mounting and electrical connections did not change significantly at the facelift, but it is worth confirming the connector type with the breaker against your registration to be sure.

Trim level does not affect horn fitment on the CLA — Sport, AMG Line, and other trim grades all use the same horn hardware. The horn is a standard safety component unchanged across the trim range, so you do not need to source one from the same trim level.

Mercedes-Benz does share components across its compact car family, and the horn used on the C117 CLA has commonality with other models on the same MFA platform such as the W176 A-Class and W246 B-Class. That said, connector and mounting details can vary, so ask the breaker to verify the part number against your CLA's registration before purchasing.

Give the breaker your full registration number so they can confirm the generation (C117 2013–2019 or C118 2019–onwards) and check the exact part number — this is the most reliable way to ensure the connector and bracket match your car. Horns are inexpensive parts, so most breakers will have them readily available from CLA dismantles.
