Mercedes-Benz B-Class Camshaft Replacement Parts

Yes, every petrol and diesel engine fitted to the Mercedes-Benz B-Class (W245 2005–2011 and W246 2011–2018) uses one or more camshafts — all variants use piston engines, so a camshaft is a fundamental internal engine component on every version ever sold. The number of camshafts depends on the engine: a DOHC (twin-cam) layout has two per cylinder bank, while a SOHC engine has one. Your V5 or a VIN check will confirm which engine code you have, and that determines exactly which camshaft you need.

Almost certainly not — the W245 (2005–2011) and W246 (2011–2018) are entirely different generations with different engine families, so camshafts from one generation will not cross over to the other. Even if the fuel type and displacement look similar on paper, the engine codes differ between generations and the camshaft profiles, dimensions and bearing arrangements are specific to each engine design. Always match by engine code, which you'll find on your V5 or via a VIN check, and confirm compatibility with the breaker against your registration.

No — trim level (SE, Sport, AMG Line, Urban, Executive) makes no difference whatsoever to camshaft fitment on the B-Class. The camshaft is determined entirely by the engine code, and SE, Sport and AMG Line models sharing the same engine code use identical camshafts. When sourcing a used part, give the breaker your engine code rather than your trim name and you'll get the right component.

The W246 ran from 2011 to 2018, with a facelift arriving in 2015, but the critical factor for camshaft fitment is still the engine code rather than the facelift year. Some engine codes carried across the facelift unchanged, meaning the camshaft could be the same, but others were revised mid-production. Confirm with the breaker against your specific registration and engine code before purchasing, as ancillary and internal specification changes mid-production are the kind of detail only the breaker can verify against your VIN.

Yes, fuel type matters significantly — petrol and diesel engines are entirely different units with different camshaft profiles, timing and lift characteristics, so a diesel camshaft will not fit a petrol engine and vice versa. Beyond petrol versus diesel, the specific engine code within each fuel type determines the exact camshaft required, as even two 2.0-litre petrol engines can have different camshaft specifications. Always supply your engine code and fuel type to the breaker to avoid an incompatible part.

In most cases the gearbox type does not directly change the camshaft specification, as the camshaft is an internal engine component independent of the transmission. However, on some B-Class variants the engine tune or software calibration differs between manual and automatic versions, and on rare occasions this can correspond to a difference in camshaft specification. To be safe, tell the breaker both your engine code and gearbox type when requesting a quote, and let them confirm the part matches your exact vehicle.
