Hi All,

The car is G21 320XD, I'm observing a strange electronic noise into the cabin. In lower speed it looks likes disappearing but in fact when I start driving after several km the noise starts. I've seen several colleagues here that have the same issue without any solution.
It makes me crazy to be honest.
If you could help me to indentify it. I would be grateful to you for your help.
