W205 C-180 whining noise Air Condition on
Hi everyone,
I'm driving a W205 C-180 petrol 2015. When i have my AC on, i hear a very loud whining noise. It is also related with the tachometer.
When i turn my ventilator of en turn it on with the AC of, the sound disappears. When i turn the AC on, the sound comes back again.
Also important to mention that i doen't have this sound the first time of the day when i drive the car. But when i for example go to the supermarktet and turn the car on again after 30 minutes, i hear this sound.
It is very strange.
I checked it at the dealer, the car stil have warranty, but they said the car is fine
What could this be?
