Discovery 3 2.7 error

Hi all you experts out there. I have a problem with my disco 3 2.7 2007
I can drive from norfolk to Scotland with no error message on dash
but when i switch engine off error message ENGINE SYSTEM FAULT comes up
i can still drive ok but at reduced power
when engine has cooled down error message disappears and car drives ok again.
message only appears when engine is warm but I can drive all day but when i switch off
and restart message reappears
I have changed the AIR INTAKE TEMP. SENSOR
got a feeling it might be turbo
anyone any ideas
