So you probably have the wrong computer in the car. I just got a disco with a bad ecm. I swapped one from one of my parts cars only to find this fault. After looking the one does not have the dmtl valve so there is no connection there, I saw a post at some point a long time ago about this but cant find it anymore now that i need it. I vaugley remember something about rewiring something but since i cant find the post i really dont know the outcome. So now im on the hunt for an ecm/bcm from a donor that did not have dmtl in it.
