Cheap Mercedes-Benz GLA AC Compressor

The GLA X156 generation ran from 2014 to 2019, with a facelift in 2017, so a 2015 and a 2018 car sit either side of that facelift boundary. The engine code is the critical detail here — if both cars share the same engine code the compressor may well be compatible, but whether Mercedes made any ancillary or mounting changes around the 2017 facelift is something you should confirm with the breaker against your registration before buying.

Engine code matters far more than year alone — a 2016 GLA 200 petrol and a 2016 GLA 220d diesel will use completely different compressors, and even within petrol variants different displacements can differ. Always supply your engine code (found on your V5C or via a VIN check) when requesting quotes from breakers, as it is the single most reliable way to match the part. Year alone is not sufficient.

Trim level does not affect which AC compressor is fitted — a GLA Sport, AMG Line, or Executive on the same engine code will use the same unit. What can vary cosmetically between trims is underbonnet appearance and bracket finishing, but the compressor itself is determined by the engine, not the specification level. Tell the breaker your engine code and fuel type and trim is irrelevant to the search.

Both the 220d and 200d are diesel variants of the X156 GLA, but they can carry different engine codes and different power outputs, which can mean different compressor specifications. Check the exact engine code on your V5C and pass it to the breaker rather than relying on the badge alone, as diesel badge names do not guarantee identical mechanical components.

The X156 generation GLA ran through to 2019, while the all-new X247 generation launched in 2020, making these two distinct platforms with little parts commonality. A compressor from an X247 (2020 onwards) is very unlikely to fit an X156, so make sure the donor vehicle year is confirmed as 2019 or earlier when you contact breakers. Always cross-reference engine codes as the final check.

On many applications a replacement AC compressor is a straightforward mechanical swap with no coding required, but whether your specific GLA requires any ECU pairing or immobiliser-related work is something you must confirm with the breaker or a Mercedes specialist against your exact registration. Do not assume it is plug-and-play without that check, as some configurations may need additional steps.
