Funny sound when turned off engine

[wills777]

When I turn off my auris hybrid 2010 anytime I turn off the engine after 2 seconds I will hear a sound as if it's releasing gas close to the abs in the engine

Hi, 

this is possible to be your brake system depressurising, perhaps a minute after switching off the car. Typical for many modern cars and all Toyota hybrids.
