Cheap Mercedes-Benz GLA Timing Chain

The GLA runs in two main generations: the X156 (2013–2020, facelifted in 2017) and the X247 (2020-onwards), and these generations use fundamentally different engines and architecture, so a timing chain from one generation will not cross to the other. Within the X156 generation, fitment depends heavily on engine code rather than year alone, so a 2014 and a 2019 GLA sharing the same engine code have a much better chance of using the same chain. Always confirm the exact engine code from your V5 or a VIN check before ordering, and verify with the breaker that the specific chain matches your registration.

The GLA 200 and GLA 250 petrol variants use different engine codes — the 200 typically uses a 1.3-litre or 1.6-litre unit depending on generation, while the 250 uses a 2.0-litre unit — and timing chains are specific to the engine, not the badge or displacement family. Trim level makes no difference to timing chain fitment; what matters entirely is the engine code. Pull your engine code from the V5 or a VIN decoder and give it directly to the breaker to ensure the correct chain is supplied.

Mercedes-Benz diesel engines fitted to the GLA, such as those carrying the OM651 engine code found in the GLA 200d and GLA 220d, do use a timing chain rather than a belt, so this is a genuine part you can source from a breaker. Petrol variants of the GLA also use timing chains across the range, so whichever fuel type your GLA is, a chain-driven setup is standard. Confirm your exact engine code with the breaker, as chain design and component count can vary between diesel and petrol families.

Trim level — whether Sport, AMG Line, Urban, or any other — has no bearing whatsoever on timing chain fitment, as this is a purely mechanical part determined by the engine fitted to the car. Two GLAs with identical engine codes will use the same timing chain regardless of which trim grade they are. The only detail worth passing to a breaker is your engine code, fuel type, and registration so they can cross-reference the exact specification.

The X156 GLA received a facelift in 2017 which brought some engineering updates, and while many engines carried over, ancillary components and exact chain configurations can sometimes change at a facelift point. Whether a pre-facelift (2013–2016) chain crosses directly to a post-facelift (2017–2020) unit is something you should confirm with the breaker against your specific registration and engine code, rather than assume. Supplying your engine code alongside your reg gives the breaker the best chance of identifying the correct chain without guesswork.

The GLA, A-Class (W176/W177), and CLA share platform architecture and in many cases use the same engine families, meaning timing chains can sometimes be common across these models when the engine codes match. However, 'sometimes' is not 'always', and subtle production changes mean you should not assume compatibility purely on the basis of shared badging. Give the breaker both your GLA's engine code and the donor vehicle's engine code and let them confirm whether the chains are identical before committing to a purchase.
