335i engine sound when car is off

Hi

I recently heard this noise when I turned my car off. I have no idea what it is.

Its coming from the passenger side

Anyone able to help?

Thanks

Had some weird shit like that too before. Could be turbos being cooled.

I think it's the electric water pump - looks like I got a big bill coming

Sounds a bit like an unhealthy pump alright

Electric coolant pump is on the way out.

I wish I could close my ears sometimes.

It is air in the water pump. Probably just sorted it's self out when everything turned off and settled. Won't do the turbos any good though as they won't be getting cooled properly.
