Used Mercedes-Benz EQS Airbag Control Module

Yes, the EQS is a fully electric luxury saloon but it is still equipped with a complete SRS (Supplemental Restraint System) including airbags and seatbelt pretensioners, all managed by a dedicated airbag control module — the absence of a combustion engine makes no difference to this system. The module controls deployment of front, side, and curtain airbags across all EQS variants. If you are searching for a used unit, you are looking for the right part on the right car.

The EQS (V297 platform) launched in the UK in 2021 and represents a single generation at the time of writing, with a facelift introduced for the 2024 model year bringing interior and exterior updates. Generation and build date do matter for the airbag module, as the SRS system configuration can vary across the facelift boundary — confirm with the breaker that any unit they hold matches your exact registration rather than assuming all 2021-onwards cars are identical.

The 2024 facelift brought meaningful changes to the EQS interior and electronic systems, which means a module from a 2021-2023 car crossing that boundary into a 2024 car is not straightforward. You should confirm compatibility of the specific module and its SRS system variant directly with the breaker, quoting your full registration number. Airbag modules are safety-critical single-use components, so professional fitting and system coding by a qualified technician is strongly recommended regardless of which unit you source.

Trim level can matter on the EQS because higher specifications include additional airbag positions and seat configurations — for instance, the optional rear executive seating arrangement on upper trims may mean additional pretensioner variants that differ from standard rear seating. Always confirm with the breaker that the module they have came from a car with the same trim and seating configuration as yours. Quoting your registration to the breaker is the safest way to match the correct unit.

The powertrain variant — whether rear-wheel drive (450+) or four-wheel drive (580 4MATIC) — does not directly determine which airbag control module is fitted, as this is an interior safety system tied to the body and trim specification rather than the drivetrain. However, SRS module compatibility with your specific system configuration is something you should still confirm with the breaker against your registration, as software and connector variants can differ. Never assume engine or drivetrain alone rules a module in or out.

Airbag control modules are safety-critical components, and fitting one incorrectly can result in airbags failing to deploy in a collision or, in rare cases, deploying unexpectedly — both outcomes are extremely dangerous. Professional fitting by a qualified technician, including SRS system coding and fault-code clearance with Mercedes-compatible diagnostic equipment, is strongly recommended. The module is also a single-use item once the system has deployed, so always confirm with the breaker that the unit has not been triggered.
