Hey,

 

When I close my car, there's a really high noise happening from somewhere under the hood, like a really high "beep"  or something like that.

What's that all about? Is it some kind of an option I can turn off?

 

It turns off after some time but it is still annoying since the car is parked close to my house and I can hear this thing pretty well.

 

Help appreciated!

Thanks.

There is a secondary (low pressure) electrical oil pump to oil around the turbo bearings to prevent sludging in there and premature turbo bearing failure. Normal.

 

Not sure why it pulses tho. I think they have some strange algorithm to maximize low-duty cycle cooling.
