Used Volkswagen Polo Airbag Control Module

This is a generation boundary question: the Polo Mk5 ran from 2009 to 2017, while the Mk6 arrived for 2018 onwards, and these are distinct platforms with different SRS systems. A module from a 2014 (Mk5) is very unlikely to be compatible with a 2018 (Mk6), but whether a specific unit will work with your car's exact SRS setup is something you should confirm with the breaker against your registration number. Never guarantee fitment across a generation change.

Yes, generation is the most important factor — the Mk4 (2001–2009), Mk5 (2009–2017), and Mk6 (2018 onwards) each have their own SRS architecture and the modules are not interchangeable between them. Within a generation there was also a facelift — the Mk5 received one around 2014 — and whether a pre- or post-facelift module crosses that boundary is something to confirm with the breaker against your registration. Always supply your full registration when requesting a quote.

The airbag control module itself is a central ECU that manages the whole SRS system, so door count can influence which curtain airbag or side-impact sensors are mapped into it. You should tell the breaker your exact door count and confirm the module they have came from the same body style. Do not assume a module from a 3-door will work straight away in a 5-door or vice versa.

Trim level can affect the SRS system because higher or sportier trims may include additional airbags or different seat-mounted pretensioner configurations — Polo trims such as S, SE, Match, and GTI have had varying seat and safety equipment specs across the years. Whether the specific module from one trim is compatible with another trim's SRS layout is something you must confirm with the breaker against your registration. As a general guide, like-for-like trim sourcing is the safest starting point.

No — the engine has no bearing on the airbag control module, which is part of the passive safety system rather than the drivetrain. What matters is the generation, trim level, and body style, not whether your Polo has a 1.0, 1.2, 1.4, or any other engine. Focus your search on finding a module from the correct generation and trim, and confirm compatibility with the breaker using your registration.

Airbag control modules are safety-critical components and professional fitting by a qualified technician is strongly recommended — an incorrectly configured or coded module could prevent the SRS system from deploying in a crash, or cause unintended deployment. Airbags and seatbelt pretensioners are single-use devices, so if the module you are buying came from a car that was in an accident, check with the breaker whether it has been triggered or fault-stored, as a deployed or fault-coded module will need specialist attention. Always have the replacement unit coded to your vehicle by a professional before driving.
