Cheap Mercedes-Benz Citan Air Flow Meter

Yes, but only on diesel-engined Citans — the common 1.5-litre diesel variants (engine codes such as K9K) use a mass air flow (MAF) sensor as part of the engine management system. Petrol-engined Citans also use a MAF sensor, so the part does exist across the range. However, always confirm the exact sensor fitted to your specific engine code with the breaker, as sensor design can vary between engine variants.

The Mercedes-Benz Citan W415 generation ran from 2012 to 2021, so both a 2013 and a 2019 vehicle fall within the same generation — which is a promising starting point for compatibility. That said, there were running production changes across that span, and whether a specific MAF sensor from a 2013 unit physically and electronically matches a 2019 unit is something you should confirm with the breaker against both registration numbers. Engine code is the key detail to check — if both vehicles share the same engine code the chances of a match are much higher.

No, trim level makes no difference to air flow meter fitment on the Citan — whether your vehicle is a standard panel van, the Tourer passenger variant, or any other body configuration, the MAF sensor is determined entirely by the engine, not the body style or trim. The engine code (found on your V5 or via a VIN check) is what you and the breaker need to match. You may find cosmetic or interior differences between a van and a Tourer, but those have no bearing on this mechanical part.

Engine code is the single most important detail for sourcing a Citan air flow meter — matching by year alone is unreliable because different engine variants were available across the same model years. The K9K 1.5-litre diesel family, for example, had different specifications and the MAF sensor calibration can differ between them. Always quote your engine code (from the V5 registration document or a VIN check) to the breaker so they can cross-reference accurately.

The Citan's 1.5 dCi diesel engine is indeed a Renault-sourced K9K unit also found in vehicles like the Renault Kangoo and certain Nissan models, so there is a realistic possibility of cross-compatibility on the MAF sensor. Whether the specific calibration, connector, and mounting arrangement match your exact Citan variant is something to confirm with the breaker, who can check part numbers against your registration. This cross-brand avenue can be a useful way to widen your search and potentially reduce cost.

A MAF sensor is generally a straightforward swap that does not require ECU coding in the way that, say, an engine control unit itself would — but whether your specific Citan requires any reset or adaptation after fitting is something to confirm with a Mercedes-trained technician or the breaker rather than take for granted. It is always worth clearing any fault codes after fitting and checking that no warning lights remain. Do not assume the used sensor will simply plug in and perform identically without any checks.
