Just googled it and they are the codes, they are also on a sticker ontop of the Cam pulley cover, above and below the bar code, the codes shown on my f super have no comparison at all so I don't know who's been messing on with this car, all I know is my pal owned it 5 year and only replaced cam sensor, a battery and regular servicing, so must be down to previous owner or the place he bought car from. I know a fiesta rs1800 needs running at 2-2,500 rpm for the ecu to learn the engine characteristics, when the battery has been disconnected for 4 hours or more so maybe these need the injectors recoding if the battery been disconnected or flat for a while
