Mercedes-Benz Viano Windscreen Replacement Parts

The Mercedes-Benz Viano was produced from 2003 to 2014, all within a single W639 platform generation, with a facelift arriving in 2010 that updated the front end and interior. For windscreen fitment the key split is pre-facelift (2003–2010) versus post-facelift (2010–2014), as subtle changes around the glass aperture and bracket provisions can affect compatibility. Always confirm the exact year of both your vehicle and the donor vehicle with the breaker before purchasing.

These two vehicles sit either side of the 2010 facelift boundary, so while both are W639-platform Vianos, there can be differences around the windscreen surround and fitments introduced at the facelift that may prevent a straight swap. Name both registration years to the breaker and ask them to confirm the part is from a pre- or post-facelift vehicle to match yours. Never assume compatibility across that 2010 boundary without the breaker verifying it directly.

No — the Ambiente, Trend, and Avantgarde are trim levels on the W639 Viano and trim level does not affect which windscreen fits. What does matter is the generation (pre- or post-2010 facelift) and whether your windscreen has heating elements or a bracket for an ADAS camera, rain sensor, or lane-assist system. Focus your search on those features rather than the trim name, and a part from any trim level will be suitable as long as those specifications match.

Look at the top of your current windscreen near the rear-view mirror for a mounted camera or sensor housing, and check for fine heating wires or a heating zone across the glass itself — both are more common on post-2010 facelift models but not universal. If you replace a heated screen with an unheated one, or miss a camera bracket, the part may not fit correctly and associated systems will not work. Tell the breaker exactly what features your existing screen has so they can match them from their stock.

No — engine and gearbox choice makes no difference to windscreen fitment on the Viano. The variables that matter are the platform generation (pre- or post-2010 facelift), whether the screen is heated, and whether it carries a bracket or provision for an ADAS camera or rain sensor. Concentrate on those points when speaking to the breaker and ignore any engine-related descriptions in listings.

A post-2010 facelift W639 Viano screen is the right generation to be looking at, but not all post-facelift screens were specified with a camera bracket, so you need one that specifically carries the correct mounting. Whether the bracket from a particular donor vehicle is compatible with your specific lane-assist or ADAS system is something you should confirm with the breaker against your registration, as this depends on the exact system fitted to your vehicle. Ask the breaker to compare the bracket design on their screen with yours before agreeing to purchase.
