GLA 220 CDI 4 matic 2014 whistling noise

Hi all,

Ive been experiencing a very loud whistling noise whilst cruising at around 2000 rpm on motorways ect, the noise only appears for around 5 - 10 seconds then stops and starts again and so on, if i tap the accelerator or let off it instantly stops, it doesnt seem to have affected engine performance its more just an annoyance than anything, has anyone else had this problem or have any solutions i could look into?

Thanks in advance for any help
