Used Mercedes-Benz Sprinter Seat Belt Pretensioner

This is an important generation boundary: the first-generation Sprinter ran from 1995 to 2006, and the second generation (W906) ran from 2006 onwards, with a third generation (VS30) arriving from 2018. Pretensioner seat belts are safety-critical components, and parts from different generations are not interchangeable – the mounting points, connector types, and SRS system integration differ between generations. Always confirm the exact part against your registration with the breaker before purchasing.

Both of these fall within the second-generation Sprinter (W906, 2006–2018), so there is a reasonable chance they are compatible, but pretensioner variants can differ across production years even within the same generation. Because pretensioners are safety-critical and single-use after deployment, you should confirm compatibility against your exact registration with the breaker before buying. Never fit a used pretensioner without verifying it matches your vehicle's SRS system.

Yes – seat belt pretensioners are side-specific, so a nearside (NS, passenger side) unit will not be the same as an offside (OS, driver's side) unit. When requesting a quote from a breaker, always specify which side you need. Fitting the wrong side is a safety risk, so double-check this with your breaker against your registration.

Trim level can influence seat fitment and pretensioner variants on the Sprinter, as higher-specification or crew-cab versions may have different seat and belt arrangements compared to a standard panel van. Because pretensioner variants are a topic you should confirm with the breaker rather than assume, always provide your full registration and describe your seat and cab configuration when requesting a quote. Do not assume a pretensioner from a different trim level is a straight swap.

Yes – the Sprinter is available in panel van, crew van, minibus, and other body configurations, and vehicles with additional rear seating positions will have pretensioners for those seats as well as the front. Make sure you specify whether you need a front or rear pretensioner, which row, and which side, as these will differ. Confirm all of this with the breaker against your registration to ensure you receive the correct unit.

Seat belt pretensioners are safety-critical components and are single-use – once deployed, they cannot be reset or reused, so any used pretensioner must be confirmed as undeployed before fitting. Professional fitting by a qualified technician is strongly recommended, as incorrect installation can affect the SRS system and may mean the pretensioner fails to operate in a collision. Always have the system checked and cleared by a professional after the part is fitted.
