Used horns vary between vehicles - and whether you call it used, second hand or a replacement, matching the right one matters. These are the details breakers need to match the right part to your car - our request form asks them so you only hear from suppliers with the correct part:
The Peugeot 407 was produced from 2004 to 2011, with a facelift arriving around 2008, and horns are a universal fitment across the entire model run — the mounting point and electrical connector are not generation-specific in the way that body panels or lights are. That said, confirm the connector type with the breaker against your registration before buying, as minor production changes can occur mid-cycle. In most cases a horn from any year 407 should drop straight in.
Trim level makes no difference to horn fitment on the 407 — SE, SR, GT, and Executive variants all use the same horn mounting and wiring. You may find the physical horn unit looks identical regardless of trim, so there are no cosmetic differences to worry about here either. Any breaker quoting you a horn off a 407 of any trim should be supplying a compatible part.
The horn itself is not body-style specific — the saloon, SW estate, and Coupé all use the same basic horn unit and operate on the same electrical circuit. The location in the engine bay may differ very slightly between body styles, but the part itself is interchangeable. Confirm the part number with the breaker if you want extra reassurance, but trim or body style should not be a barrier here.
No — whether your 407 has a petrol or diesel engine, turbocharged or not, the horn is independent of the drivetrain and is fitted to all variants. You do not need to match engine codes when sourcing a used horn from a breaker. Simply quote your registration so the breaker can confirm the correct connector and bracket style for your specific car.
The 2008 facelift updated the 407's exterior and some interior features, but the horn assembly sits in the engine bay and was not a component that changed as part of that refresh. Pre- and post-facelift horns are generally interchangeable, but because minor running changes can occur across a production boundary it is worth confirming the connector type with the breaker against your registration before purchasing. In practice most buyers find no issue swapping horns across this boundary.
Ask the breaker to confirm the electrical connector type and the number of terminals on the horn unit matches what is currently on your car, as these are the only variables likely to cause a fitment issue. Providing your full registration number will help the breaker cross-reference the exact specification for your build date. The horn itself is a straightforward part with no complex variants, so sourcing one from any 407 of any year, engine, or trim is a reasonable starting point.
