Second Hand Mercedes-Benz Vito Crankshaft

This question crosses the boundary between the W639 generation (2003–2014) and the W447 generation (2014 onwards), and that boundary matters enormously for a crankshaft because the engine family changed completely between the two. Even if both vans share a similar displacement on paper, the internal architecture is different enough that a W639 crankshaft will not slot into a W447 block. Confirm the exact engine code from your V5 or a VIN check and supply it to your breaker so they can match like-for-like.

Yes, both a 2007 and a 2011 Vito sit within the W639 generation (2003–2014), so you are at least in the right ballpark, but crankshaft compatibility within that generation depends heavily on the specific engine code rather than the year alone. The W639 used several different four-cylinder and V6 diesels whose cranks are not interchangeable with one another, so a 2.1-litre OM646 crank, for example, will not fit a 3.0-litre OM642 block. Always match on engine code and confirm the specific part number with your breaker before purchasing.

No, trim level has no bearing whatsoever on crankshaft fitment — Pro, Progressive, and Premium are specification packages that affect interior features, comfort equipment, and cosmetic details rather than anything mechanical inside the engine. What matters entirely is the engine code stamped on your engine block or listed on your V5, your fuel type (diesel in virtually every UK Vito), and which generation your van belongs to. Strip away the badge and give your breaker the engine code and they will be able to find the correct crankshaft.

Yes, fuel type matters in principle because a petrol and a diesel engine have fundamentally different internal components, but in practice the overwhelming majority of Mercedes-Benz Vito vans sold in the UK are diesel, so a petrol crankshaft query is unusual. Even within diesel variants, different engine codes — for example OM651 versus OM642 in the W639 and W447 ranges — use different crankshafts, so fuel type alone is not enough. Provide your full engine code to your breaker and they will confirm the correct part.

The gearbox type itself does not change the crankshaft specification, because the crankshaft lives entirely inside the engine block and is independent of what is bolted to the back of it. That said, some engine-and-gearbox combinations were only offered together by Mercedes, so if your van has an automatic the engine code can still help your breaker verify the full drivetrain spec and rule out any ancillary differences at the rear of the engine. Supply your engine code and registration to your breaker and let them cross-reference both details for a confident match.

The single most important detail is your engine code, which you will find on your V5 registration document, via a VIN decoder, or stamped on the engine block itself — for the W639 generation (2003–2014) common codes include OM646 and OM642, while the W447 generation (2014 onwards) typically uses the OM651 family in UK spec. Alongside the engine code, tell your breaker your van's registration, the generation, and your fuel type to help them cross-reference their stock accurately. Never buy a used crankshaft on year and model alone — the engine code is what determines the correct internal dimensions and fitment.
