Cheap BMW i3 Horn

Yes, the BMW i3 is fitted with a standard 12V horn like any other road car — the high-voltage drivetrain does not affect this, as the horn runs off the conventional 12V auxiliary battery. All variants of the i3, including the standard battery versions and the Range Extender (REx) models, have a horn fitted as standard. If you are struggling to find one listed, search for 'BMW i3 horn' or ask a breaker directly against your registration.

The BMW i3 was facelifted in 2017, which brought exterior and interior changes, but the horn is a simple 12V unit mounted behind the front bumper and is generally unaffected by facelift revisions. That said, because the 2017 facelift did bring some structural and trim changes to the front end, it is worth confirming with the breaker that the mounting bracket and connector match your specific car using your registration. There is a reasonable chance a pre-facelift horn will cross over, but do not assume this without checking.

Trim level does not affect horn fitment on the BMW i3 — the horn is a functional safety component and is not varied between trim grades such as the entry-level, Suite, or Range Extender-equipped cars. You may find the horn itself looks cosmetically different from different donor cars depending on age, but the part that matters is the electrical connector type and mounting, not the trim level. Any used horn from an i3 of the same generation is worth considering, subject to confirming compatibility with the breaker.

The i3s is a sportier variant of the i3 with wider tracks and different bumper styling, which could affect how the horn is mounted or accessed, but the horn unit itself is the same type of basic 12V component. There is a good chance a standard i3 horn will physically interchange with an i3s, but because of the front-end differences, confirm the mounting position and connector against your registration with the breaker before buying. Never assume a part fits based on shared branding alone.

It is possible that a horn from another BMW model shares the same 12V specification and connector, as BMW tends to use common components across its range, but this is not guaranteed and the i3's unusual construction — including its carbon fibre passenger cell — means front-end mounting points may differ from conventional BMW models. We would not recommend buying a horn from a different model without first checking the connector type, mounting bracket, and voltage rating match your i3. Ask the breaker to confirm compatibility against your registration to be safe.

The BMW i3 was produced from 2013 until 2022, so there are a reasonable number of cars being broken in the UK and used horns should be available through dismantlers. The 2017 facelift is the main generation boundary to be aware of, so ideally source a horn from a car of the same era as yours and confirm fitment with the breaker using your registration. Because the i3 is an increasingly popular car to break as values soften, availability of used parts is growing.
