Hopefully someone can help me out. I am dealing with a problem I never seen before. I currently am working on a 01.5 S4 (6 speed with ESP), my problem is for some reason the cluster is not communicating with the abs controller. There's an abs light on along with the brake light and to make things even more strange the rpm on the cluster does not work. If I go into instruments with the vag and go to adaptations group 60 and change the code from 1025 (esp) to 0 (non esp) the rpm signal on the cluster works!! The car came with a "T" box ecu from the factory. It now has a chipped "M" box in it. According to the vag the cluster and ecu are seeing one another but no communication from the cluster to the abs or from the ecu to the abs. I even tried switching clusters, abs control module and abs controller, still same outcome. I checked the wiring of the can bus from the ecu to cluster to abs and everything seems fine. The ecu is coded for esp as well, If anyone can help I would really be grateful. Below is a copy of the auto scan. Again any input would be appreciated.
