Hi guys recently found an oil leak on my 2007 R56 One and have been scratching my head as to what this thing is called so I can find out what sort of gasket it needs can any of yous help ? It is a bad picture so I apologize in advance. I've circled the component that is leaking the the screenshot below and any help will be greatly appreciated. The engine is the 1.4l and the component is located next to the thermostat sensor
