Used Mercedes-Benz GLE Door Lock Mechanism

The GLE in this era covers the W166 generation (roughly 2015–2019), so a 2016 and a 2019 are within the same generation and the mechanism is more likely to be compatible — but you must match the side (NS or OS) and confirm with the breaker against your exact registration, as late W166 production changes can affect fitment.

The V167 generation launched in 2019 replaced the W166, and these are distinct platforms, so mechanisms from the two generations are not interchangeable — always tell the breaker which generation your vehicle is and give them your registration to confirm.

Yes, door lock mechanisms are side-specific, so you must specify NS (nearside, passenger/left) or OS (offside, driver/right) when requesting a quote — ordering the wrong side means the mechanism simply will not fit.

Trim level does not affect door lock mechanism fitment on the GLE; the mechanism is determined by the generation and the door side, not the trim grade — the main trim differences you may encounter are cosmetic items like interior door furniture, which can be swapped or resprayed and do not affect whether the lock unit itself fits.

No, the door lock mechanism is part of the door structure and is entirely unrelated to the drivetrain or engine type — a diesel GLE and a petrol or hybrid GLE of the same generation use the same mechanism on the equivalent door side.

The GLE W166 was actually a direct continuation of the ML W166 platform and shares significant components, meaning there is a strong chance of compatibility — however, given that Mercedes did make revisions when rebranding to GLE, you should confirm with the breaker against both registrations before purchasing.
