Hi everyone,
I have an 2015 i30, CRDI and a persistent problem with the smell from the vents. The forum threads I've found mostly talk about the smell from the A/C when it's turned on, but my issue is the opposite. There's a really nasty smell that appears the moment the A/C is turned OFF (but only if AC was running earlier). If I just start the car and do not turn the A/C, there is no smell. If I then turn on the A/C, still no smell. But the moment I turn A/C off, the smell is really bad. It doesn't matter how long the A/C was running - even if I activate it just for a few seconds (even accidentally, literally click A/C button on then off), the very strong smell appears and would not go away for at least half an hour.
I tried aircon bombs (smell returns in full after a day or two), chaniging pollen and A/C filters (again, smell returns very quickly).
Any idea what's causing it and how to fix it?
Would be grateful for advice! Thanks
