Second Hand Mercedes-Benz GLS Instrument Cluster

The GLS nameplate covers two main generations: the first-generation GLS (X166), produced from 2016 to 2019, and the second-generation GLS (X167), which launched in 2020 and remains in production. The instrument cluster differs significantly between these two generations, so getting the right generation is the single most important factor when sourcing a used unit. Check your V5C registration year and confirm with the breaker which generation applies to your vehicle.

Both the 2017 and 2019 GLS fall within the first-generation X166 range, so on the face of it you are comparing like-for-like within the same generation. That said, Mercedes did introduce software and hardware revisions across the X166's production run, and whether a specific unit from 2017 will plug straight into a 2019 car is something you should confirm with the breaker against your registration number.

The 2020 model year marks the changeover from the first-generation X166 to the second-generation X167, and these two generations use entirely different instrument cluster designs, connectors, and software architectures. Fitting a second-generation cluster into a first-generation GLS is not a straightforward swap and is very unlikely to be compatible. Stick to sourcing a cluster from within your own generation and confirm the exact part with your breaker.

The GLS was offered in trim levels including SE Line and AMG Line (among others depending on market year), and while interior styling does vary between trims, the core instrument cluster unit is largely driven by generation rather than trim. You may find minor display configuration differences depending on optional equipment fitted to the donor vehicle, so it is worth describing your trim level and any factory-fitted options to the breaker so they can match as closely as possible.

Engine choice — whether diesel, petrol, or hybrid — does not fundamentally determine instrument cluster fitment on the GLS, and you should focus on generation and build date rather than engine code when searching. The cluster may display slightly different readouts depending on the engine in the donor car, so mention your engine type to the breaker as a secondary check, but do not rule out a part on engine alone without consulting them first.

Give the breaker your full registration number so they can pull the exact build specification, and also confirm the model year and generation (X166 for 2016–2019 or X167 for 2020 onwards). It is also helpful to mention your trim level and any factory-fitted options such as widescreen digital displays, as these can affect the cluster variant. The more detail you provide upfront, the better chance the breaker has of supplying a unit that matches your car.
