Moin Together, I’m driving a Volvo v60 t6 twin engine from 2020. I’m very happy with the vehicle so far and that’s been for almost 2 years. Yesterday I heard a new noise while driving and I can’t yet explain what it is and where it comes from. After a few minutes (2,3 minutes) I hear an electric buzz from the front right. The buzzing goes away after about a minute and I don’t hear the ride about it any more. When I restarted the same game. I thought that it might be the fuel heater and this morning just turned on the stand heating: sounds quite normal. My suspicion is that the air conditioning system has been cooled down in some way. Yesterday, however, I imagined that the noise went away when I deliberately pushed the ac button (so switched off). But can also be by chance. How does the air conditioning work at the phev? Is the compressor purely electric or is driven by a belt? If the latter works: how does it work, if the petrol engine is off and I drive electrically? Maybe you have to have a good idea again.
