Second Hand Alfa Romeo 155 Airbag Control Module

Yes, the Alfa Romeo 155 was fitted with an SRS airbag system, and an airbag control module (also called an airbag ECU or SRS module) is part of that system. It was introduced as the safety electronics landscape developed through the 155's production run from 1992 to 1998, though not all very early cars may have had full SRS provision, so it is worth confirming with the breaker exactly what your car has fitted against your registration.

The Alfa Romeo 155 ran from 1992 to 1998 and received a facelift in 1995, and the SRS system configuration could differ across that boundary, meaning a pre-1995 module may not be directly compatible with a post-1995 car. You should treat the facelift year as a likely fitment boundary and confirm with the breaker that the module matches your specific registration and SRS system before purchasing. Because airbag modules are safety-critical components, professional fitting is strongly recommended.

The airbag control module itself is tied to the generation and the specific SRS system fitted to the car rather than trim level branding as such, though trim variants with different seat or interior specifications could have variations in the overall SRS setup. Confirm with the breaker that the module matches your car's exact SRS configuration against your registration rather than relying on trim name alone. Professional installation by a qualified technician is essential given the safety-critical nature of airbag systems.

Airbag control modules are single-use items once the system has deployed — after a deployment event the module stores fault data and is effectively locked out, so a replacement unit from a breaker is the correct solution rather than resetting the original. You must ensure the replacement module is compatible with your exact SRS system, which your breaker can help verify against your registration. Because this is a safety-critical system, fitting must be carried out by a professional, not at home.

Engine type does not determine airbag control module fitment — the module relates to the car's SRS system and interior specification, not the drivetrain. Whether your 155 has a 1.8, 2.0 Twin Spark, V6, or any other engine makes no difference when sourcing this part. Focus instead on the model year relative to the 1995 facelift, and confirm compatibility with the breaker against your registration.

A used airbag control module from a reputable breaker is a legitimate and common way to source this part, provided it has not previously been deployed and comes from a car whose SRS system matches yours — confirm both points with the breaker against your registration. Because airbag systems are safety-critical, the module must be fitted by a qualified technician who can also check and clear any SRS fault codes correctly. Never attempt to fit or test airbag components yourself.
