From some brief reading it be more of a general fault code than anything specific to the turbo...recommendation was to pull fault codes, however you do that.

I'll keep kicking it around the interweb though.

EDIT: upon further reading, it appears that light is a check engine light, rather than anything specific to the turbo itself. The green light appears to be turbo-specific, but I'm still unclear as to what exactly it indicates.
