Moin, the topic has been with me since my first VOLVO (XC60 from 2014). In the meantime, I have the third (V90 from 12/19; and my wife also – currently XC90) and with each of my VOLVO the air conditioning has some unpleasant smells. Strangely, this is only the case with my vehicles, which my wife also have a much lower mileage and do not know the phenomenon. With my two predecessors it occurred each after more than 100,000km, so usually shortly before delivery, so that it didn’t disturb much. Now my just 40,000 km down and smells (feeling rather wet weather) very muffy again. The interior filter has already been exchanged twice. I have already wondered if something is wrong (automatic is always active), but could not find anything. Does anyone know this phenomenon?
