I am investigating a car which seems perfect when speed less than 100 km/h. When driven more than 100 km/h, there is a side noise somewhere, but I have no idea where it comes and how. Everything has been checked 12/2016, next time 12/2017. Very nice piece othertise, driven 170 000 km, no accidents, nice bottom of the car - - no damages.
Side noise: I hear a continuous side noise (from the right side) which comes you drive faster than 100 km/h. I does not come from tires, because tested with other set. I do not see any leakages in the motor. There is no noise when you drive less than 100 km/h.
- I think the noise is not like the one in the video here coming from the right headlight, but exclude it completely. I cannot understand why the side noise occurs at the higher speed only - - maybe because vibration only then significant.
Which typical effects can cause a side noise when driving 100 km/h?
Car: Alfa Romeo 159 1.9 JTS 4d
Kilometers: 170 000
