Mercedes-Benz GLE Seat Belt Pretensioner Replacement Parts

The GLE W166 generation ran from 2015 to 2019, so a 2016 and a 2019 are both within the same generation, which is a good starting point for compatibility. However, pretensioner variants can differ within a generation, and this is a safety-critical part, so you should confirm the exact part number matches against your registration with the breaker before buying. Never fit a used pretensioner that has previously been deployed, as these are single-use devices.

The W166 ran from 2015 to 2019 and the V167 is the next generation, launched in 2019, so these are distinct platforms and the parts are very unlikely to be interchangeable. You should treat these as separate generations and source a pretensioner specific to your V167. Confirm the exact variant against your registration with the breaker, as pretensioner types can vary even within a generation.

Trim level can influence seat belt and pretensioner fitment on the GLE because higher trims such as AMG Line may have different seat configurations compared to standard Sport trim, and the pretensioner is integrated with the seat belt assembly. You should tell the breaker your exact trim level as well as your registration to help them identify the correct part. Because this is a safety-critical component, always confirm the specific variant with the breaker rather than assuming trim-to-trim compatibility.

Yes, side matters — nearside (NS, passenger side) and offside (OS, driver side) pretensioners are handed and are not interchangeable with each other. Always specify NS or OS when requesting a quote from a breaker. Fitting the wrong side is a safety risk, so double-check this before purchasing.

Seat belt pretensioners are safety-critical components and, along with airbags, form part of your vehicle's SRS restraint system, so professional fitting by a qualified technician is strongly recommended. Used pretensioners must never have been previously deployed, as they are single-use devices and a fired unit will not protect you in a collision. A professional will also be able to check that the replacement unit is compatible with your specific SRS system before installation.

Yes — you should provide your full registration number, the generation (W166 2015–2019 or V167 2019-onwards), your trim level, and whether you need the nearside or offside unit. Pretensioner variants can differ within the same generation, and confirming these details against your registration gives the breaker the best chance of supplying the correct part. Because this is a safety-critical component, do not rely on year alone to establish fitment.
