Help required regarding new Cultus strange noise

[hasan4u]

Hello Pakwheelers,

I have bought Cultus VXL 2018 model, previously I owned Passo 2015 model. There is strange noise that I notice normally at night when there is minimal outside noise. This noise comes when car is in 2nd,3rd, 4th,5th gear and vanishes when I left foot of accelerator or press clutch. This is very slight noise not that much but definitely its there.This noise is not engine noise that's for sure.

Is this normal noise in cultus or only my car has it?

Thanks

What kind of noise is it?
Seems like gear humming noise.

Can't explain that noise, may be close to whistle
