Mercedes-Benz Viano Headlight Replacement Parts

The Viano was built as a single generation spanning 2003 to 2014, based on the W639 platform, with a facelift introduced in 2010 that brought updated front-end styling including revised headlights. Lights from within the pre-facelift period (2003–2010) should generally be compatible with other pre-facelift Vianos, and the same applies within the post-facelift range (2010–2014). Always confirm the exact part against your registration with the breaker before buying.

These two vehicles sit on either side of the 2010 facelift boundary, so the headlights are likely to be different designs. The 2008 model is pre-facelift and the 2012 is post-facelift, and front-end panels including lights typically change at a facelift. Confirm with the breaker whether the specific unit they have matches your post-facelift 2012 registration before purchasing.

No — wheelbase does not affect headlight fitment on the Viano, as the front-end panels are shared across different body lengths within the same generation. The key questions are which generation your vehicle belongs to and whether it is pre- or post-facelift. Confirm the exact part with the breaker against your registration to be sure.

Trim level does not change the physical fitment of the headlight on the Viano — the same front-end structure is used across Ambiente, Trend, and Avantgarde variants within a given facelift period. However, you may find cosmetic differences between units, and some higher trims may have been fitted with xenon rather than halogen lights from the factory. Check with the breaker whether the headlight they have matches your lighting type as well as your registration's facelift period.

NS (nearside) refers to the left-hand side of the vehicle as you sit in the driver's seat, and OS (offside) is the right-hand side — so the NS headlight is the passenger side and the OS is the driver's side on a right-hand-drive UK Viano. Breakers will list these as NS or OS, so make sure you specify which side you need when requesting a quote. Double-check the side when you receive the part, as left and right units are not interchangeable.

The Viano and the contemporary Vito share the W639 platform and were sold alongside each other, so there is a possibility of front-end parts crossing over, but this is not guaranteed as trim and specification differences can affect exact compatibility. The V-Class is a different generation and is unlikely to share the same headlight units. Confirm compatibility with your breaker by providing your full registration before buying.
