I’m replacing the thermostat/housing on my 2011 Mini Countryman All4S and found this blue part laying towards the back of the engine. Anyone know what it is or where it goes? I’ve. Counted he parts listings on RealOem and can’t seem to identify it.

Also anyone know what size Torx bit fits the transmission fill bolt? https://cimg1.ibsrv.net/gimg/minicoo...778b196fa.jpeg
