Mercedes-Benz EQS Seat Belt Pretensioner Replacement Parts

Yes, the Mercedes-Benz EQS is fitted with pyrotechnic seat belt pretensioners as standard across all variants — these are a core part of the passive safety system, just as they are on any modern Mercedes-Benz regardless of drivetrain type, so the fact that the EQS is fully electric makes no difference here. Pretensioners fire in a significant collision, locking the belt tight to restrain the occupant, and like airbags they are single-use components that must be replaced after deployment. If yours has triggered or is faulty, a used pretensioner from a breaker is a viable route, but professional fitting by a qualified technician is strongly recommended given the safety-critical nature of the part.

The EQS (Z297 generation) launched in the UK in 2022 and has not received a full generation change within the current production run, so a 2022 and a 2024 car share the same fundamental platform and interior architecture. That said, Mercedes-Benz did introduce a mid-cycle refresh for the 2024 model year with interior and trim revisions, and pretensioner variants can differ even within a generation, so you should confirm compatibility against your specific registration with the breaker before purchasing. Never assume fitment without that check on a safety-critical part like this.

Trim level can matter for the EQS because the range spans significantly different interior specifications — from the standard EQS 450+ through to the AMG EQS 53 — and seat configuration and belt anchor points can vary accordingly. The pretensioner itself is tied to the specific seat and belt assembly for that position, so a pretensioner from a high-spec Hyperscreen or AMG-trimmed car may not directly suit a standard-trim EQS, or vice versa. Confirm your trim level with the breaker and check the part against your registration to be sure.

Yes, this is important — seat belt pretensioners are side-specific and are not interchangeable between the nearside (NS, passenger side) and offside (OS, driver side). When contacting a breaker on Findapart, always specify whether you need the NS or OS pretensioner, and also whether it is for the front or rear seat position, as these will be different parts. Getting the wrong side is a straightforward mistake to make, so double-check this before ordering.

Seat belt pretensioners are safety-critical components connected to the vehicle's SRS (supplemental restraint system), and incorrect fitting can result in non-deployment in a crash or, in the worst case, accidental deployment during installation. Professional fitting by a qualified technician with the appropriate diagnostic equipment to reset and verify the SRS system is strongly recommended. Many breakers and garages will also advise this, and it is worth factoring the fitting cost into your budget when sourcing the part.

The EQS is a purpose-built, fully electric vehicle on its own dedicated platform (Z297), which is distinct from the combustion-engined S-Class (W223) or any hybrid variant, so pretensioners from those models are very unlikely to be a direct fit even though the cars share a market position. Engine or drivetrain type does not affect pretensioner fitment on its own, but the underlying platform, body structure, and seat design do, so parts should only be sourced from another EQS (Z297). Confirm the donor vehicle's registration and trim level with your breaker to maximise the chance of a correct match.
