A Genuinely Useful Diagnostic Technique Worth Trying First — Toyota Aygo Cabin Air Filter
If you're chasing a musty or damp smell and have already changed the cabin filter without success, this is genuinely worth trying: switch specifically between "fresh air" and "recirculate" settings and see if the smell only appears on fresh air. If so, this points toward the external air intake area (the scuttle, at the base of the windscreen) as the genuine source rather than the filter itself. Debris can accumulate in this intake and block the drain, allowing standing water and decaying organic matter to develop a genuine, persistent musty smell that a filter change alone won't resolve.
It's also worth knowing that a genuine, documented Technical Service Bulletin has covered cases where the metal used within the air conditioning condenser itself can generate a distinctive musty smell, with affected cars under warranty qualifying for a condenser replacement rather than simply another filter change.
Toyota Aygo Cabin Air Filter: Easy to Forget, Easy to Fix
There's no performance downside to a neglected Toyota Aygo cabin filter, which is precisely the problem: nothing about how the car drives will tell you it needs changing, so it often gets forgotten until a musty smell or weak airflow forces the issue.

Toyota Aygo Cabin Air Filter: What It Does
Don't confuse this with the Toyota Aygo's engine air filter — they're unrelated parts. The cabin filter's job is cleaning air before it reaches the ventilation system, catching dust and pollen, with activated-carbon versions also filtering some airborne odours.
