Used Mercedes-Benz GLA Engine

The GLA H247 generation ran from 2020 onwards, while your 2018 car sits in the first-generation X156 (2013–2019), so both a 2014 and 2018 GLA are within the same X156 generation — a good starting point for compatibility. However, fitment really comes down to the engine code rather than the year alone, since Mercedes used several different units across that generation (for example M270 four-cylinder petrols and OM607/OM651 diesels), and there were running production changes throughout. Pull your engine code from your V5 or a VIN check and make sure the donor car shares the same code before going further. Confirm ancillary and mounting details with the breaker against your registration, as mid-production changes can affect whether everything lines up.

The X156 ran from 2013 to 2019 and the H247 launched in 2020, and these are distinct platforms with different engine families, so straight swapping across that generation boundary is very unlikely to be straightforward. Engine codes, mounts, ancillaries, and management systems differ significantly between the two generations. Name the exact engine code from both vehicles when speaking to a breaker, and confirm with the breaker against your registration whether any crossover is feasible.

No — trim levels like Sport, AMG Line, Urban, and Executive on the GLA are cosmetic and equipment packages; they do not change the engine fitted to the car. The engine in an AMG Line GLA 200 d is mechanically the same as in a Sport or Urban GLA 200 d of the same year, because the engine code follows the drivetrain designation, not the trim badge. Do be aware that AMG Line cars may have different undertray covers or cosmetic engine-bay dressing that won't be included with a used engine, but that won't affect whether the engine itself fits. Always match on engine code rather than trim name.

Your engine code is the single most useful detail you can give a breaker — it's more reliable than the year or badge because Mercedes fitted several different engines to the same model across its production run. You'll find it on your V5C registration document, or you can run a VIN check through a service like the DVLA or a paid decoder to get the exact code. For the X156 GLA common codes include M270 (1.6/2.0 petrol), M133 (AMG 45), OM607 (1.5 diesel), and OM651 (2.1 diesel), though always verify your specific car. Give that code directly to the breaker so they can match it precisely.

The 220 d and 200 d are different power outputs and in the X156 generation used different engine variants, so they are not automatically interchangeable even though both are diesel. The engine code is what determines fitment, not the badge on the boot — a 200 d and 220 d can share a base block family but differ in tuning hardware, injection calibration, and associated components. Check the engine code on your V5 or via a VIN check, pass that to the breaker, and confirm against your registration whether the specific donor unit is a match. Never assume two diesel badges mean the same engine.

Both a 2017 and 2019 GLA sit within the first-generation X156 (2013–2019), which is encouraging, but there were running production and specification changes across those years that can affect ancillaries and mountings even within the same generation. The engine code must match between your car and the donor — if they share the same code, you're in the best position for fitment. Confirm with the breaker against your registration that mounts, sensors, and ancillary points are compatible for your specific build date, as mid-production changes are not always reflected in general listings.
