Hello everyone…. I have a question about a noise that can be heard for about 4 weeks. V70 III 2014 D5 215 hp automatic 134tkm down I bought the car with 94000 20 months ago…there was not yet the buzz. The noise is speed-dependent and very strong to hear at about 1300 revolutions. When I set to N during the ride and the speed is increased it is also to hear. Tempomat at 55 kmh and I hear it permanently. I was my Volvo dealer and he said it might be d the timing belt or the alternator. The timing belt is only due at 180 tkm. Is there anyone here who is familiar with all this ? What would you do in my place ? Thank you already Thomas
