Strange noise from engine left side
Hey!

i have a strange pulsing/buzzing noise from legt engine side when engine is heated.

M276 2020 glc43

sounds like something is touching something or like pump… not sure but it can be heard with the hood down.

car drives perfectly, no errors, recently did B service - no issues.

what could be wrong, should I fix it asap or is it something what is not very dangerous and just makes the sound?

thanks!!
