General HELP - injector system warning light???

[LJB]

I hav a punto gt, and so does my dad. As far as i know if u fit a bleed valve the injector system light comes on under hard use (on my dads). I had a bleed valve so wasnt worried bout light coming on under hard use, but i took the valve off and it still randomly comes on, not always under hard use? Surely it shouldnt come on wiv standard boost???
PLEASE HELP- much appreciated!
