Hi, before I make a theatre for the last warranty service, I would like to ask if this is perhaps normal: With my V60 D3 the air conditioning system is relatively loud, i.e. partly clearly audible. However, this was already so with my V50 and does not bother me very much. But what is unusual is that in thrust mode this noise turns on and down, it turns softer and louder again in about a second. If any of you also have this swelling and lowering noise d He air conditioning? Thank you, greeting
