Used Mazda 3 Sun Visor

These two cars belong to different generations — the second-generation Mazda 3 (BL) ran from 2009 to 2013, while the third-generation (BM) launched in 2013, so a 2014 donor visor is BM and your 2012 car is BL, and the two will not interchange. Always confirm the exact generation with the breaker using your registration and theirs before ordering.

Yes, generation is the primary fitment factor — the first-gen (BK, roughly 2003–2009), second-gen (BL, roughly 2009–2013), and third-gen (BM, roughly 2013–2019) each have different interior architectures and sun visor designs that are not interchangeable between generations. Within the same generation, visors are generally consistent, but always confirm with the breaker against your registration to be sure.

Yes, side matters because driver's (OS, offside) and passenger's (NS, nearside) sun visors are handed differently and are not interchangeable. When contacting a breaker, specify clearly whether you need the NS or OS visor so they can pull the correct part.

Trim level can affect the sun visor if one trim includes extras such as a vanity mirror with lighting while another does not, so a visor from a Sport may look slightly different to one from an SE even within the same generation. The mounting and fitment should be the same across trims within a generation, but check with the breaker whether the vanity mirror spec matches yours if that matters to you.

Sun visors are roof-mounted interior parts and are not affected by door count, so a visor from a 5-door Mazda 3 of the same generation should be the same part as one from a 3-door. Confirm this with the breaker against both registrations to be certain, as there can occasionally be minor production variations.

No — engine type has no bearing on interior parts like sun visors, so whether your Mazda 3 has a petrol or diesel engine makes no difference to which visor fits. Focus on getting the correct generation and the correct side (NS or OS) and the part should be suitable.
