Mercedes-Benz GLA EGR Valve Replacement Parts

Yes, but only on diesel variants — the GLA diesel engines (such as the 2.1-litre CDI units found in the X156 generation from 2013 onwards, and the 2.0-litre diesel in the X247 generation from 2020) use EGR valves as part of their emissions management systems. Petrol-engined GLAs do not have an EGR valve, so if you drive a petrol GLA you will not find this part on your vehicle. If you are unsure which engine you have, check your V5C or confirm with your registration number before searching for this part.

Both years fall within the first-generation GLA, known as the X156, which ran from 2013 to 2019 — however, fitment of a used EGR valve still depends on matching the engine code exactly, as Mercedes used more than one diesel engine variant across this generation. A 220 CDI and a 200 CDI unit, for example, are unlikely to share the same EGR valve even though both are X156 models. Always confirm the engine code (found on your V5C or stamped on the engine block) with the breaker before purchasing.

Yes, the X156 and X247 are completely different generations built on different platforms, and you should treat them as non-interchangeable for this part — the X247 moved to a newer 2.0-litre diesel engine family with updated emissions hardware to meet Euro 6d standards, whereas X156 diesels used the older 2.1-litre CDI family designed around earlier Euro 5 and early Euro 6 rules. Even if an EGR valve from the wrong generation looks visually similar, it may not seal or calibrate correctly for your engine. Confirm the generation and engine code with the breaker against your registration before ordering.

No — trim level has no bearing on EGR valve fitment whatsoever; SE, Sport, AMG Line and Urban trims are cosmetic and equipment-based distinctions that do not change the engine or its emissions components. What matters is the engine code and the emissions standard the vehicle was built to, not what badge is on the tailgate. Focus your search on matching the engine code and fuel type, and let the breaker check those details against your registration.

Yes, this is an important consideration — Euro 5 and Euro 6 GLA diesels may use differently calibrated EGR systems to meet their respective emissions standards, and fitting a unit from the wrong emissions era could affect engine performance or cause an MOT failure. The X156 GLA spanned both Euro 5 and early Euro 6 production years, so two X156s of different model years may not share the same EGR valve even if the engine code looks similar. Confirm the emissions standard and full engine code with the breaker against your exact registration to be sure.

No, the 4MATIC all-wheel-drive system is mechanically separate from the engine's emissions components and has no influence on EGR valve fitment. The relevant factors remain the engine code, fuel type, and emissions era — a 4MATIC diesel and a front-wheel-drive diesel GLA with the same engine code should require the same EGR valve. Confirm the engine code with the breaker regardless, as it is the engine specification rather than the drivetrain layout that determines this part.
