Second Hand Mercedes-Benz Citan Door Lock Mechanism

The Citan ran as the W415 (first generation, 2012–2021) and the W420 (second generation, 2021-onwards), and these are distinct platforms with different door and latch designs, so a lock mechanism from the W415 generation is very unlikely to fit a W420 or vice versa. Always confirm the exact generation with the breaker against your registration before purchasing.

Yes, absolutely — the Citan is available as both a panel van and a combi/Tourer with different door configurations, and the front door lock mechanisms are side-specific (NS for nearside/passenger-left, OS for offside/driver-right). For the rear, the Citan's sliding side door uses a different lock mechanism to any hinged rear door, so you must specify which door you need the mechanism for when contacting a breaker.

It can do — the W415 Citan was offered in both standard and long wheelbase variants, and sliding door components including lock mechanisms can differ between wheelbases due to the door's size and runner configuration. Make sure you confirm your wheelbase alongside your registration when asking a breaker for a quote.

The door lock mechanism is a mechanical fitment item and trim level alone does not typically affect which mechanism is used — what matters is the generation, the specific door position (NS or OS, front or sliding), and body configuration. However, always cross-reference your registration with the breaker to confirm, as equipment-level differences between van and Tourer/combi variants can occasionally affect ancillary components built into or around the lock assembly.

A 2018 Citan falls within the W415 first generation (2012–2021), while a 2021 Citan sits right at the boundary between the W415 and the incoming W420 second generation — so your 2021 vehicle could be either generation depending on exact build date. You should confirm your vehicle's generation with the breaker using your registration before assuming a 2018-sourced part will fit.

No — the door lock mechanism is entirely unrelated to the engine variant fitted to your Citan, so whether you have a diesel or petrol engine makes no difference to fitment. What matters is the generation, the door position (NS or OS), and whether the door in question is a hinged front door or a sliding side door.
