Accuracy note: this part is genuinely consistent across the range, since it's part of the HVAC system rather than the drivetrain — the same reference applies to the closely related Seat Mii and Skoda Citigo, which share the same small-car platform.

A Genuine Prevention Habit, Plus a Glovebox Step Worth Knowing First — Volkswagen Up! Cabin Air Filter

A genuinely well-corroborated preventive habit worth adopting, confirmed repeatedly across owner forums: running the air conditioning year-round, rather than only in summer, measurably reduces musty smell developing in the first place. The mechanism is straightforward — regular AC use keeps the evaporator drying out properly between uses, while a system left dormant over autumn and winter gives moisture, and the mould that feeds on it, a genuine chance to establish itself before the following spring. A related, equally simple habit: a couple of minutes before finishing a journey, switch the AC compressor off but leave the blower fan running — this dries out the evaporator and ducting properly rather than leaving them damp when the car is switched off.

A specific access step worth knowing before you start: on many current-generation models, there's a linkage rod on the right side of the glovebox (connected to the glovebox light switch mechanism) that needs to be disconnected first — pull firmly on its base toward the rear of the car until it releases — before the glovebox will drop down far enough to reach the filter housing behind it. Trying to force the glovebox down without releasing this first risks snapping the linkage.

If a musty smell persists even after fitting a genuinely fresh filter, it's worth looking beyond the filter itself — a dirty or mould-affected evaporator coil, or a partially blocked condensate drain tube, are both common underlying causes that a filter change alone won't fix. A specialist AC clean and disinfection service addresses these directly if the smell doesn't clear with a fresh filter and the habits above.

Easy to Forget, Easy to Fix

Unlike most parts covered here, this one has no bearing on how the car drives or performs — its only job is air quality inside the cabin, which makes it very easy to forget about entirely until something forces the issue.

Before you buy: filter size and whether your car uses a standard or activated-carbon filter varies by trim. Always confirm against your VIN before ordering.

What It Does

The cabin air filter cleans incoming air before it reaches the car's ventilation system, trapping dust, pollen and, on activated-carbon versions, some airborne odours and pollutants. It has no connection to the engine air filter, which is a completely separate part serving the combustion process rather than the cabin.

These are the same regardless of make or model — see our full Cabin Air Filter Guide for signs it needs changing, confirming fitment against your VIN, and choosing standard, carbon, or HEPA media.
