Second Hand Alfa Romeo 155 Seat Belt Pretensioner

Yes, the Alfa Romeo 155 was fitted with pyrotechnic seat belt pretensioners as part of its passive safety system, though the exact specification could vary by trim level and production date. If you are sourcing a used pretensioner, confirm with the breaker that the unit matches your specific car's SRS setup using your registration number.

The Alfa Romeo 155 ran from 1992 to 1998, with a facelift introduced in 1995 that brought interior and trim revisions which could affect pretensioner specification. Parts from within the same pre- or post-facelift period are the more straightforward match, but whether a pre-facelift pretensioner crosses over to a post-1995 car is something you should confirm with the breaker against your registration before buying.

Trim level can matter for interior parts on the 155 because seat and belt configurations varied across the range, so it is worth telling the breaker your trim grade alongside your registration. Common UK-market grades included base, Super, Cloverleaf, and the Q4 — if your car has sport seats or a different belt anchorage arrangement to a standard car, the pretensioner may differ, so do not assume all trim levels share the same unit.

Yes, nearside (passenger) and offside (driver) pretensioners are handed and are not interchangeable, so always specify which side you need when contacting a breaker. Double-check the side on the part itself if possible, as fitting the wrong side is a safety risk on a safety-critical component like this.

A used pretensioner is only safe to fit if it has never been deployed — pretensioners are single-use pyrotechnic devices and cannot be reset or reused after activation. Always confirm with the breaker that the unit has not fired, and strongly consider having the part fitted and the SRS system checked by a qualified mechanic, as incorrect installation of a safety-critical component can put occupants at serious risk.

Seat belt pretensioners are safety-critical components integrated with the car's SRS system, and incorrect fitting can prevent them from deploying correctly in a crash or cause accidental deployment during installation. We strongly recommend having a used pretensioner fitted and the SRS system inspected by a professional rather than attempting a DIY installation.
