Second Hand Mercedes-Benz Vito Washer Pump

The Mercedes-Benz Vito has gone through distinct generations — the W638 (1996–2003), the W639 (2003–2014), and the W447 (2014–present) — and washer pumps are generally not interchangeable across these generation boundaries due to differences in connector types and mounting. Within the same generation, fitment is more likely to carry across model years, but always confirm the part number with the breaker against your registration before buying.

No — trim level, whether that's Sport, Tourer, or any other Vito variant, does not affect washer pump fitment; the pump is determined by the generation and body configuration, not how the van is spec'd. You may find cosmetic differences in how the pump is presented or packaged, but the functional part itself is trim-independent, so don't let trim level put you off a pump from a different spec vehicle of the same generation.

A 2013 Vito is a W639 (the generation that ran from 2003 to 2014), while a 2015 Vito is a W447 (the generation introduced in 2014), so these are different generations and the washer pump is unlikely to be a straight swap. Because this crosses a generation boundary, we'd strongly recommend confirming compatibility with the breaker using both vehicles' registrations before purchasing.

No — the washer pump is not engine-specific, so whether your Vito has a diesel or a different engine variant within the same generation, the pump should be the same. Focus on matching the generation rather than the engine when searching for a used part.

Not necessarily — where a rear wash-wipe system is fitted, the rear washer pump (or a second outlet on a dual-outlet pump) may differ from the front, so it's important to specify to the breaker whether you need the front or rear pump. Check your own vehicle first to confirm whether it has a rear washer, as not all Vito configurations include one, and then ask the breaker to match accordingly.

There is some parts-sharing across the Mercedes-Benz van range, and pumps from related vehicles like the Viano (which shares the W639 platform with the Vito of the same era) may well interchange, but this is not guaranteed for every application or year. Confirm the part number with the breaker against your Vito's registration to make sure you're getting a compatible unit rather than assuming platform sharing means a straight fit.
