Second Hand Mercedes-Benz GLA Door

The GLA runs in two clear generations: the X156 (first generation, 2013–2020) and the X247 (second generation, 2020–present), and doors are not interchangeable between these two generations as the body structures differ entirely. Within the same generation, doors from any year in that range are your best starting point for a match, but always confirm the exact model year with the breaker against your registration before buying.

Both the 2015 and 2018 GLA fall within the first-generation X156 (2013–2020), so a door from that era is broadly the right family. That said, confirm with the breaker against your registration that no mid-cycle production changes affect your specific door, as subtle running changes can occur within a generation.

This question spans a generation boundary: the 2019 GLA is a first-generation X156, while the 2021 GLA is a second-generation X247, and these two generations use different body shells. A door from one generation will not fit the other, so make sure you source a door from the correct generation by confirming your registration with the breaker.

Yes, side is critical — a nearside (NS, passenger/left) door and an offside (OS, driver/right) door are completely different panels and are not interchangeable. Always specify NS or OS clearly when requesting a quote from the breaker, using your registration to confirm which side you need.

Trim level does not affect door fitment on the GLA; the door shell and frame are the same across SE, Sport, AMG Line, and similar grades within the same generation. You may find cosmetic differences such as mouldings, glass tint, or badging between trim levels, but these are finishing details and do not change whether the door physically fits — confirm any visible differences you'd like to match with the breaker.

Colour is not a fitment concern — a door from any colour GLA of the correct generation and side will fit your car physically. Used doors will nearly always need a respray to match your vehicle anyway, so focus on getting the right generation, side, and condition rather than the colour.
