Used Vauxhall Vectra Airbag Control Module

Yes, all Vauxhall Vectras were fitted with an airbag control module (also called the SRS ECU or airbag ECU) as standard across the range. It sits at the heart of the supplemental restraint system, triggering the airbags and pretensioner seat belts in a collision. Because it is a safety-critical component, professional fitting is strongly recommended.

No — the Vectra B (1995–2002) and Vectra C (2002–2008) are entirely different generations with different SRS systems, wiring, and connectors, so the modules are not interchangeable. Always source a module from the correct generation to match your car. Confirm compatibility with the breaker against your exact registration before buying.

The Vectra C received a facelift in 2005, and there can be differences in the SRS system configuration across that boundary, so a module from a 2003 car may not be a straightforward swap into a 2006 car. Name the facelift year to your breaker and confirm compatibility against your registration, as this is one of those details that varies by build date rather than model year alone. Professional fitting and system-reset after installation are essential regardless.

Trim level can affect fitment because higher trims such as Elite may include side curtain airbags or additional sensors that require a different module configuration compared with a base Club. Give the breaker your full trim name and registration so they can match the correct module to your specific SRS setup. Do not assume a module from a different trim level is a straight swap, even within the same generation.

Airbag control modules are effectively single-use: once the system has deployed, the module stores crash data and will not allow the airbags to fire again, so a replacement unit is required. A used module from a breaker is a common and cost-effective solution, but it must be professionally installed and coded or reset to your vehicle's SRS system. Confirm with the breaker that the module they supply has never been involved in a deployment before purchasing.

Body style and door count can influence the SRS configuration, particularly if your car has curtain airbags, so it is worth telling the breaker the body style alongside your registration. The core module location and generation are the primary fitment factors, but differences in airbag count between body styles mean the module must match your car's specific setup. Always confirm against your registration with the breaker rather than assuming any same-generation module will work.
