Mercedes-Benz Citan Airbag Control Module Replacement Parts

Yes, the Citan is fitted with an airbag control module (also called the SRS control unit) as standard across its production run, covering both the first generation (W415, 2012–2021) and the second generation (W420, 2021-onwards). The module manages the airbag and seatbelt pretensioner systems throughout the vehicle. Because this is a safety-critical component, always have it replaced and coded by a qualified technician rather than attempting a DIY fit.

Both a 2015 and a 2019 Citan sit within the first-generation W415 range (2012–2021), so they share the same platform and the module is more likely to be compatible than one from across the generation boundary. That said, compatibility with your specific SRS system configuration is something you must confirm with the breaker against your registration, as pretensioner variants and software calibration can differ. This is a safety-critical part, so always have fitment and coding carried out by a professional.

The W415 ran from 2012 to 2021 and the W420 launched in 2021, and these are distinct generations with different vehicle architectures, so a module from across that boundary is very unlikely to be a straight swap. You should confirm compatibility with the breaker against your specific registration before purchasing, as SRS system configurations differ between generations. Given that airbag modules are safety-critical and single-use after deployment, professional fitting and coding is essential regardless of which generation you are sourcing from.

For the W415 Citan, trim levels such as Basic, Worker, and Tourer can affect the airbag and seat configuration — for example, Tourer variants are passenger-focused with more seating rows, which may influence the SRS system layout. While the core module may be similar across trims, you should confirm with the breaker that the unit they have matches your trim's specific SRS setup, particularly regarding the number of seats and any side airbag provisions. Always verify against your registration to be safe, and have the replacement coded by a qualified technician.

The Citan W415 was available in different body configurations including panel van and the multi-seat Tourer, and door count or body style can influence the overall airbag system layout, particularly if side curtain airbags or additional sensors are fitted. The airbag control module itself may vary depending on which sensors and airbag circuits it is configured to manage. Confirm the exact body style and door configuration of the donor vehicle with the breaker against your registration before buying, and ensure a professional carries out the fitting and any required coding.

Airbag control modules are safety-critical components, and fitting one incorrectly can result in airbags failing to deploy in a collision or deploying unexpectedly, both of which are extremely dangerous. A used module will also require professional coding to your vehicle's SRS system to function correctly, which is not something that can be done without specialist diagnostic equipment. Always have this work carried out by a qualified technician, and confirm with the breaker that the unit is compatible with your specific vehicle before purchase.
