Used Mercedes-Benz GLA Camshaft

Yes, all Mercedes-Benz GLA variants use internal combustion engines — petrol or diesel — and every one of those engines has at least one camshaft, typically one per cylinder head (DOHC setups have two per head), so it is a genuine and commonly sourced used part. The camshaft you need depends entirely on the specific engine fitted to your car, not just that it is a GLA. Give the breaker your engine code from your V5 or a VIN check to make sure you get the right one.

The original GLA (X156 generation) ran from 2014 to 2019, with a facelift arriving in 2017, so a 2015 and a 2019 car are both X156s but sit either side of that facelift boundary. Camshaft fitment follows the engine code rather than the model year, so if both cars share the same engine code the part may well be compatible, but you should confirm with the breaker whether any ancillary or timing-chain changes were made at the facelift point for your specific engine. Never assume compatibility on year alone.

The second-generation GLA (H247) launched in 2020 and is a significantly different car from the first-generation X156 (2014–2019), with new engine families and revised architecture. A camshaft from an X156 is very unlikely to suit an H247 engine even if the displacement and fuel type look similar, because the engine codes differ. Always match on engine code, and ask the breaker to cross-reference against your registration to be certain.

No, trim level has no bearing on camshaft fitment. Sport, AMG Line, and Executive trims on the GLA are differentiated by cosmetics, alloy wheels, interior trim, and equipment levels, not by the engine internals. What matters is your engine code — two GLA models with identical engine codes will use the same camshaft regardless of which trim badge is on the tailgate. The only exception would be if different trims were offered with genuinely different engines, in which case it is the engine code that differs, not the trim itself, that drives the part selection.

Yes, absolutely — petrol and diesel engines have different camshaft profiles, dimensions, and often different numbers of camshafts per head, so they are not interchangeable. Beyond fuel type, the specific engine code is the most important detail you can supply, as Mercedes-Benz fitted several different petrol and diesel units across the GLA range. Have your V5 or a recent VIN check to hand when contacting a breaker so they can match the part precisely to your engine.

Mercedes-Benz does share engine families across multiple models, so a camshaft from a same-era C-Class or A-Class running an identical engine code to your GLA could well be the correct part. The key check is that the engine codes match exactly, not just the displacement or badge; breakers routinely source camshafts this way and it is an accepted practice. Confirm the match with the breaker against both registrations before purchasing, as minor production changes can sometimes affect ancillary fittings even within the same engine family.
