Second Hand Mercedes-Benz V-Class Fuel Injection Pump

The Mercedes-Benz V-Class W447 generation runs from 2014 onwards, so both a 2016 and a 2019 model sit within the same generation — however, the engine code is the critical factor here, not the year alone, so you need to confirm both vehicles share the same engine code (found on your V5 or via a VIN check) before assuming interchange. There was a facelift in 2019 that brought revisions to the W447, and whether ancillary fittings or mounting points changed around that boundary is something you should confirm directly with the breaker against your registration. Never assume fitment on year alone.

The W447 V-Class received a facelift in 2019, and while the core engine architecture may be shared, whether the injection pump itself or its mounting and connections changed across that facelift boundary is not something that can be stated as fact here — confirm this with the breaker against both registrations. Your engine code, which you can find on your V5 or through a VIN check, is the most reliable thing to quote when asking a breaker about cross-facelift compatibility. Treat the 2019 facelift as a boundary that warrants checking rather than assuming.

Trim levels like Sport or AMG Line on the V-Class are specification packages affecting cosmetics, comfort, and styling — they do not change the engine or fuel injection pump fitted, provided the engine code is the same. A pump pulled from a standard V-Class with the same engine code as your AMG Line will be mechanically equivalent; you may simply find differences in surrounding components like covers or brackets, but the pump itself is unaffected by trim. Always match on engine code and fuel type rather than trim badge.

The fuel injection pump follows the engine code above everything else — for the W447 V-Class the diesel variants have used engine codes including OM651 (2.1-litre four-cylinder) and OM654 (2.0-litre four-cylinder), depending on year and output, but you should verify your specific code from your V5 document or a VIN check rather than relying on the badge alone. Quoting the exact engine code to the breaker is the single most useful thing you can do to get an accurate match. If you are unsure of your code, any reputable breaker can look it up against your registration.

Whether a used fuel injection pump requires coding or pairing to your vehicle's ECU or immobiliser system is something you must confirm with the breaker and ideally with a Mercedes-Benz specialist before purchasing — this cannot be stated as a blanket fact here, as it can vary by system and build date. Some modern diesel injection systems do involve software calibration, and fitting a pump that cannot be correctly coded could leave your vehicle running poorly or not at all. Always raise this question explicitly with the breaker when getting your quote.

The V220d and V250d are different power outputs of the same V-Class W447 platform, but whether they share an identical injection pump depends on their specific engine codes — both use diesel engines but the fuelling and pump calibration may differ between outputs. Check the engine code on each vehicle's V5 or via a VIN check and quote both codes to the breaker so they can confirm compatibility. Do not assume that sharing a body or generation guarantees pump interchange across different power variants.
