The Boxer & Relay 2.2 2006 on 100/120ps & 2.4 Land Rover Defender 2.4’s have the same EGR control bytes in their ECU as the Transits that use the same “Puma” engine.. so its possible to delete the EGR function from the system.. With the EGR delete itself worth up to 1mpg on good day, this could be a worthwhile conversion..
