Second Hand Mercedes-Benz GLS Sunroof

Yes, the GLS is a large premium SUV and sunroofs or panoramic glass roofs were offered across the range, often as standard on higher specifications and available as an option on others. The GLS is a genuine candidate for a used sunroof assembly. Because sunroofs were fitment-dependent on specification rather than a universal fitment across every single car built, confirm with the breaker that the donor vehicle was actually fitted with a sunroof before proceeding.

The X166 and X167 are completely different platforms with different roof structures, so a sunroof or panoramic roof assembly from the X166 will not fit the X167. These are distinct generations with separate glass, frame, and track dimensions, so you must source the sunroof from the correct generation matching your car. Always confirm the exact build year of both your car and the donor vehicle with the breaker against your registration.

Trim level does not affect sunroof fitment in the way that body style or generation does — the key variables are the platform generation and whether the donor car was actually fitted with a sunroof at all. In practice, higher trims such as AMG Line or Grand Edition were more likely to have panoramic roofs fitted as standard, while base-spec cars may not have had one; the glass and frame assembly itself is the same across trim levels on the same platform. Confirm with the breaker that the sunroof type (single-pane versus full panoramic) on the donor car matches what was fitted to yours.

No — the engine type has no bearing on sunroof fitment whatsoever. The roof structure and sunroof assembly are determined by the body and platform generation, not by what is under the bonnet. Source from the correct generation (X166 or X167) and confirm the donor car was sunroof-equipped, and engine type can be safely ignored.

The GLE and GLS share architectural heritage within the Mercedes SUV range, but the GLS is a longer, larger seven-seat vehicle with a different roofline and roof structure, so a direct swap is not straightforward. Whether specific panels or assemblies interchange between the GLE and GLS of the same platform generation is something you must confirm with the breaker against both registration numbers, as this falls into the category of same-platform variants sold under different names where pressing and dimension differences can catch buyers out.

The X166 GLS received a mid-cycle update in 2017, but whether this brought any pressing or structural changes to the roof or sunroof assembly is something you should confirm with the breaker rather than assume either way. Provide the breaker with your full registration so they can check the exact specification of both your car and the donor vehicle. Matching the build year as closely as possible is the safest approach when sourcing a used sunroof for any updated model.
