Second Hand Mercedes-Benz GLA Coil Pack

Yes, but only on petrol-engined GLA variants — diesel engines use a compression-ignition system and have no coil pack or spark plugs at all, so if you have a diesel GLA (such as the 220d or 200d), a coil pack is not the part you need. Petrol variants including the 200, 250, and AMG 45 use individual ignition coils, and the set is commonly referred to as a coil pack. If you're unsure which engine you have, your V5 registration document or a free VIN check will show the fuel type and engine code.

The GLA X156 ran from 2013 to 2019, with a facelift arriving around 2017, but both sit within the same X156 generation sharing the same petrol engine family. Fitment is primarily driven by the engine code rather than the facelift year, so a coil from a pre-facelift 200 petrol and a post-facelift 200 petrol with the same engine code will typically share the same part. However, ancillary changes can occur mid-production even within a generation, so confirm compatibility with the breaker against your exact registration before buying.

The H247 GLA launched in 2020 as a clean-sheet redesign and uses different engine architecture compared to the X156, so you should treat these as separate parts across the generation boundary. The engine codes changed between generations, and the coil pack design is unlikely to be interchangeable. Always confirm the engine code from your V5 or a VIN check and supply it to the breaker so they can match the correct part.

Trim level — whether SE, Sport, AMG Line, or Executive — has no effect on coil pack fitment whatsoever, as the coil pack follows the engine, not the badge or interior specification. What matters is whether both cars share the same engine code; a GLA 200 petrol and a GLA 200 AMG Line with identical engine codes will use the same coil. The AMG Line trim simply adds cosmetic and suspension tweaks, so don't let the trim name put you off a correctly engine-matched coil from a breaker.

The GLA, A-Class (W176/W177), and CLA share engine families across certain generations, and coils from the same engine code will often be identical regardless of which model they came from. The engine code is the key — if a breaker's A-Class or CLA donor car carries the same engine code as your GLA, the coil is very likely compatible. Confirm this with the breaker using both registrations or engine codes, as this is a common and legitimate cross-model source for good-value used parts.

Most petrol GLA engines are four-cylinder units and therefore have four individual ignition coils, one per cylinder. You don't have to replace all four at once, but many mechanics recommend doing so as a set since the coils age at a similar rate and a second failure shortly after is common. When buying from a breaker, check whether they're supplying a single coil or the full set, and confirm the engine code matches yours to ensure you're getting the right part.
