Used Mercedes-Benz GLA Air Filter

The GLA runs across two main generations — the X156 (2013–2020) and the X247 (2020 onwards) — and 2015 and 2019 both fall within the X156 generation, so there is a reasonable chance the filter will interchange if the engine codes match; the key check is that your engine code is identical, since a 1.6 petrol, 2.0 petrol, and 2.1 diesel each take a different filter even within the same generation. Give the breaker both registration numbers so they can confirm on their system before buying.

Engine code matters far more than year for the air filter — the GLA X156 alone was offered with multiple petrol and diesel engines (including 1.6 and 2.0 petrol units and a 2.1 diesel), each with its own airbox and filter size. Matching year alone risks ending up with the wrong part. Your engine code is stamped on the V5C or available from a free VIN check, and supplying it to the breaker is the most reliable way to get the right filter.

The X156 ran from 2013 to 2020 and the X247 replaced it from 2020, and these are completely different platforms with redesigned engine bays and different engine families, so the air filter housing and filter itself are very unlikely to interchange across that generational boundary. Even if you find a part that looks similar, confirm fitment with the breaker against your exact registration before purchasing.

Trim and specification names like GLA 200, GLA 250, or GLA 220d reflect different engines rather than cosmetic grades, so in this case the badge does directly point to the engine — a GLA 250 runs a 2.0 petrol while a GLA 220d runs a 2.1 diesel, and these take different air filters. Where two cars share the same engine code but differ only in equipment level (for example, standard versus AMG Line interior), the air filter will be the same; it is always the engine code, not the trim name, that determines the correct part.

Yes, every GLA variant — petrol or diesel — has an air filter, as all internal combustion engines require one to clean intake air before it enters the engine. Fuel type does matter for fitment because the airbox design differs between petrol and diesel variants, and within each fuel type there can be further differences depending on the specific engine code. Always confirm your engine code with the breaker alongside your fuel type to make sure the filter is a match for your exact car.

The X156 GLA received a facelift in 2017, and while both the pre-facelift (2013–2017) and post-facelift (2017–2020) cars sit within the same generation, there can be ancillary and mounting changes introduced during a production run that are not always well documented. If your engine codes are identical the filter element itself is likely compatible, but to be safe ask the breaker to confirm against both registrations, particularly whether the airbox housing matches, before committing to the purchase.
