Hello Guys, i'm new in this forum. I was worried about a strange noise.

I wanted to ask if anybody know about this noise. This is a Volvo s60 2013 diesel with start stop system. When the car stops using the start stop system , a strange noise happens, i don't know but i think this is not normal.

I uploaded a video that i filmed so you can hear the noise, while the car is stopped .



Thank you for your help in Advance!
