Some advice please

Hi all,
Anyone come across EAS issues? I have a P reg range rover 2.5 diesel and the suspension is high, all the lights are like a christmas tree on the dash and EAS fault showing on the LED. is this a big (expensive) repair does anyone know ?
many thanks and apologies if i've posted in the wrong forum area!
