What would be interesting is if anyone could record the sound and post it.
My noise is more like a muffled resonance low hertz "whoooo...-like" sound.

My dealer tried a different set of tires, not the solution. I have a new appointment in february, there is a servicebullentin that som version of the prop shaft support bearing can cause noise. My dealer is ordering the updated part. Next appointment they will tear the car down and check the part number on the bearing, and if it is the faulty version replace it.
The bearing sounds like a probable source of the noise to me. I hope it does the trick. I will post the result when done

Exciting news! Think I will call my dealer on monday to hear, if they've heard about that! |
Did you get any answer? |

Spoken to two dealers and they haven't heard anything about any service bulletin, either.
Jugga, could you try to get the service bulletin number from your dealer?

I think it's hard to pick up on a microphone in the cabin.
