Fitment on a used seat belt varies by vehicle, so a bit of detail goes a long way. Our request form covers what breakers need to know, so every quote you get back is for the correct part:
Both years fall within the third-generation W176 A-Class (2012–2018, facelift 2015), so a pre-facelift belt and a post-facelift belt are from the same generation — but confirm with the breaker against your registration whether the pretensioner variant is identical across that 2015 facelift boundary, as subtle changes can occur. Side (NS or OS) and door count (3-door or 5-door) must also match. Because seat belts contain pretensioners, which are safety-critical single-use devices, professional fitting is strongly recommended.
No — the W169 (2004–2012) and the W176 (2012–2018) are completely different generations with different body structures, so their seat belts are not interchangeable. Always source a belt from the correct generation matching your registration. Confirm the exact part with the breaker before purchasing.
Trim level can affect seat belt fitment on the A-Class because Sport and AMG Line models may use sport seats with differently routed or styled belt assemblies compared with SE. Tell your breaker your exact trim level so they can match the correct belt. Side (NS/OS) and door count also need to match, and because seat belts are safety-critical, professional fitting is recommended.
The fourth-generation W177 A-Class ran from 2018 onwards, so ask the breaker to supply a nearside (NS) front belt from a W177 donor car. Confirm any pretensioner variant details with the breaker against your specific registration, as these can differ. Seat belts with pretensioners are safety-critical and should be fitted by a professional.
Door count matters for seat belt fitment because the B-pillar geometry and mounting points can differ between 3-door and 5-door body styles, so you should source a belt from the same door count as your car. Make sure the generation, trim, and side (NS or OS) also match. Confirm the exact compatibility with the breaker against your registration before buying.
Seat belt pretensioners are single-use safety-critical devices — if the donor car was involved in a collision that deployed the pretensioner, that belt must not be reused. Ask the breaker to confirm the belt comes from an undeployed, undamaged vehicle, and check the webbing and buckle carefully on receipt. Professional fitting by a qualified technician is strongly recommended for any seat belt replacement.
