Volvo V40 Cabin Air Filter: OEM Part Number
| Standard particulate filter | Volvo OEM part, specific to generation — confirm via VIN |
|---|---|
| Cars with IAQS (Interior Air Quality System) | Genuinely require the activated-carbon version to function correctly — the IAQS sensor detects pollutants and the carbon filter is what actually absorbs them; fitting a plain paper filter to an IAQS-equipped car means the system detects pollution but can't filter it out, even though the paper filter physically fits the same housing |
Volvo V40 Cabin Air Filter: Easy to Forget, Easy to Fix

A Genuinely Useful Piece of Context Worth Knowing About Persistent Smells — Volvo V40 Cabin Air Filter
If a musty smell keeps returning despite regular filter changes, this is genuinely worth knowing: documented cases on related Volvo models describe a dealer resolving an annual mould smell during servicing by spraying a specific evaporator disinfectant product onto the coil, a step distinct from simply fitting a new filter — worth knowing this additional treatment can make a genuine difference.
It's also worth knowing an honest access difficulty: pushing the new filter back into place without removing the glovebox entirely is notoriously fiddly on related models.
