A used horn that fits one vehicle won't always fit another - even within the same model range. These questions help breakers match stock to your exact vehicle before they quote:
The Mazda CX-5 runs across two generations: the first generation (Mk1) covered 2012 to 2017, and the second generation (Mk2) ran from 2017 onwards. Horns within each generation are very likely to be physically compatible, but crossing the Mk1-to-Mk2 boundary is less certain given changes to the front end and mounting points. Confirm with the breaker that the part number or mounting arrangement matches your registration before buying.
The 2014 facelift updated the Mk1 CX-5 but the car remained in the same first generation through to 2017, so a horn from a 2014-2015 car is very likely compatible with a 2016-2017 Mk1 car. That said, minor changes around the facelift mean it is worth confirming the part against your registration with the breaker before committing.
Trim level does not affect horn fitment on the CX-5 - the horn is a mechanical component that is the same across SE, SE-L, Sport, and GT Sport grades within a given generation. You may find minor differences in bracket or wiring connector style depending on build date rather than trim, so confirm the connector type with the breaker, but do not rule out a part simply because it came from a different trim.
Engine choice makes no difference to horn fitment on the CX-5 - the horn is mounted in the front of the car independent of the drivetrain and is the same part regardless of whether the donor car was a 2.0 petrol or 2.2 diesel. You can safely disregard the engine type when searching for a used horn.
All three of those years sit within the second-generation (Mk2) CX-5, which launched in 2017, so a horn from a 2017 or 2018 car is very likely to be a direct fit for a 2019 model. Confirm the mounting bracket and connector match your car's registration with the breaker to be sure, but generation compatibility is a good starting point.
Before buying a used horn, it is worth checking the fuse and horn relay first, as these are cheap and commonly cause the same symptoms as a failed horn. If the fuse and relay are fine and the horn still does not work, a used horn from the same generation CX-5 sourced through a UK breaker is usually a straightforward swap; ask the breaker whether the unit they have was tested before removal if possible.
