Used Mercedes-Benz Vito Clutch Master Cylinder

Only on manual-gearbox versions — the Vito has been sold with both manual and automatic transmissions, and a clutch master cylinder only exists where there is a clutch pedal, so automatic variants never had one. If your Vito is an automatic, there is no clutch master cylinder to replace; what you may actually be looking for is a brake master cylinder or a gearbox component. Always confirm your gearbox type before ordering.

These are entirely different generations of Vito — the W638 ran from 1996 to 2003 and the W639 from 2003 to 2014 — and the two are not interchangeable for this component. The engine family, bulkhead design, and hydraulic layout changed significantly between generations, so a part from one will not suit the other. Confirm the correct generation against your registration before approaching a breaker.

The engine code matters above almost anything else — within the W639 generation (2003–2014), Mercedes used several diesel units including the 109 CDI, 111 CDI, and 115 CDI variants, and the master cylinder specification can differ between them. Always find your engine code on your V5 or via a VIN check and pass it to the breaker, as this is the single most reliable way to ensure you are quoted the correct part. Do not assume all W639 cylinders are identical just because the van looks the same from the outside.

No — trim level has no bearing on clutch master cylinder fitment whatsoever, as Sport, SE, and Pure are essentially specification packages covering interior, cosmetics, and equipment rather than mechanical changes. What matters is the engine code, the gearbox type (manual only), and the generation of van. You may receive a cylinder pulled from any trim level and it will be mechanically equivalent, so do not pay extra or hold out specifically for a Sport-trim donor vehicle.

Both a 2010 and a 2014 Vito fall within the W639 generation (2003–2014), so they share the same broad platform, which is encouraging. However, there were running production changes and potential ancillary differences across that span, so whether this specific cylinder crosses that mid-production boundary cleanly is something you should confirm with the breaker against both registrations and engine codes. Never assume fitment on the basis of generation alone without the breaker checking both vehicles.

No — the W447, which replaced the W639 from 2014 onwards, is a substantially redesigned van and the clutch master cylinder from a W447 will not be a direct fit on a W639. The two generations differ in bulkhead layout, hydraulic connections, and engine family, making cross-generation swaps on this component impractical without significant modification. Source a part from the correct generation and confirm engine codes with the breaker to get an accurate match.
