Cheap Mercedes-Benz Citan Window Regulator

The Citan W415 ran from 2012 to 2021, and window regulators within this generation are generally consistent in design, but fitment depends on the specific door position (NS or OS), whether you have a sliding or hinged rear door, and the wheelbase variant for sliding doors. The Citan W420 arrived for 2022 onwards and is a completely different generation, so parts from the two generations will not cross over. Always confirm the exact generation against your registration with the breaker before buying.

Both a 2015 and a 2019 Citan fall within the same W415 generation (2012–2021), so the regulators are likely compatible provided the door position matches — NS front, OS front, or the correct sliding door for your wheelbase. That said, confirm with the breaker using both registrations to rule out any mid-run production changes, as these can occur without a formal facelift.

No — 2021 is the final year of the first-generation W415, while 2022 marks the start of the all-new second-generation W420, which is a substantially different vehicle. Parts from these two generations should be treated as non-interchangeable. Confirm both registrations with the breaker, as this is a clear generation boundary.

Trim level does not affect window regulator fitment on the Citan; the regulator is determined by the generation, door side (NS or OS), and for rear doors whether it is a sliding or hinged unit and the wheelbase length. The Tourer passenger variant and the van body share the same door frame engineering, so a regulator from a Worker or Base panel van will fit the same door position on a Tourer. Be aware that interior trim panels and switches may differ between variants, but the regulator mechanism itself is not trim-specific.

Yes, for sliding door regulators wheelbase does matter — the sliding door dimensions differ between short and long wheelbase Citan models, so a regulator from one may not suit the other. For the front doors this is not a factor; the key variables there are simply the generation and NS or OS side. Always tell the breaker your exact wheelbase as well as your registration when sourcing a sliding door regulator.

Yes, absolutely — window regulators are side-specific and a nearside (NS, passenger/left) unit will not fit the offside (OS, driver/right) door and vice versa. In UK convention, NS is the kerb side and OS is the driver's side, so make sure you are clear which side has failed before contacting a breaker. Getting this wrong is one of the most common reasons a used regulator is returned, so double-check before you order.
