Been carrying out some repair work on the throttles i.e.removing and refitting after specialist repair. Read fault codes before starting and made a note. On completion cleared the codes all but one, 27d0 fuel pressure control adaption factory max stored fault present. The eml is not illuminated and car runs ok. I think the code has been present for some time but don't know if had anything to do with the throttle body fault.

Anyone know what the fault means
