Used Mercedes-Benz Vito Cylinder Head

The Mercedes-Benz Vito spans two main generations here: the W639 (2003–2014) and the W447 (2014 onwards), so a 2010 donor and a 2015 recipient sit on opposite sides of that boundary and are very unlikely to be compatible. The most important thing to match is the engine code, not the year — check your V5 or run a VIN check to get it, and supply it to the breaker so they can compare it directly against the donor unit. Never assume fitment across a generation boundary without the breaker confirming engine code compatibility against your specific registration.

Yes — the cylinder head follows the engine, not the badge or model year, so two Vitos from the same year can require completely different heads if they carry different engine codes. Common Vito diesel codes include the OM646 family in the W639 generation and the OM651 family in the later W447, and heads from these units are not interchangeable even if the vans look identical. Always locate your engine code from the V5, a VIN check, or the engine bay plate before approaching a breaker, as it is the single most useful detail you can give them.

Trim and body designation make no difference to cylinder head fitment; what matters is the engine code, fuel type, and gearbox type. The Tourer is a passenger-carrying variant of the same Vito platform, so if two vehicles share the same engine code they will use the same head regardless of whether one is a panel van and the other a Tourer. Focus your search on matching the engine code rather than the trim name, and confirm the exact specification with the breaker against your registration.

The W639 generation ran from 2003 to 2014, so on paper you are in the same generation as a 2007 donor, which is a good starting point. However, Mercedes made running changes to ancillaries and mounting points during that production run, so whether a specific donor head from a different year within the W639 bolts straight on is something you need to confirm with the breaker against your registration and engine code rather than assuming it. Giving the breaker both engine codes — yours and the donor's — is the safest approach.

The cylinder head itself is not directly altered by gearbox choice, but gearbox type can indicate different engine variants or states of tune that may have subtle differences in the head casting, porting, or ancillary provisions. It is worth mentioning your gearbox type to the breaker when you enquire, so they can cross-reference it alongside the engine code and confirm the donor head is a match for your specific setup. As always, supply your full engine code and registration for the most accurate check.

The CDI badge numbers like 113 and 116 refer to power outputs rather than different engine families, and within the W639 generation both are likely to use engines from the same OM646 or OM651 family depending on exact specification, but the power difference can mean different injector configurations or other internal variations that affect the head. The most reliable way to establish compatibility is to compare the actual engine codes from both vehicles rather than relying on the badging. Confirm the match directly with the breaker using both engine codes, and be aware that ancillary differences may require additional parts.
