Local Nanocom/Hawkeye service required to clear fault codes

Hi. I have a 2001 Discovery 2 Td5. The Air Con radiator fan is always on regardless of temperature, so I have just taken the fuse out for now. Another thread suggests this is due to the ecu logging a high temperature in the past and that this permanently enables the air con radiator fan until the fault code is cleared. Does anyone have either a Nanocom or Hawkeye locally (Tewkesbury, Gloucestershire area) that would be willing to assist?
