Hello guys,I am asking for help to diagnose possible cuase of vibration on my audi , after visiting two different garages who failed to solve it. I have an A4 avant quattro 2013 245ch 3.0 Tdi automatic.Symptoms:feel vibration while driving at speeds between 120-140kmh mainly, peaking close to 130front axle change didnt make any noticable difference.after using a phone to detect vibrations, i notice frequency is proportional to number of rotations of the tires at the corresponding speed.problem persists with two different sets of tires, with different rimswheel balancing and convergence has been made 2 timesreving up the engine in neutral show no signs of vibration, so i would exclude it from the causes As far as i am checked the remaining causes can be transmission, wheel bearings or suspension.Any suggestions and help would be appreciated. Below is a recording of phone accelerometers and speed of car at the corresponding time.
