I have replaced the abs sensor lead to no avail . new wheel bearing , abs sensor , drive shaft - ran perfectly for 500miles then : abs, engine , stability control , limp diesel lights on , c1155 obd2 code shows.
now shows limp diesel/ engine warnings when started - apply braking pedal kicks back and grinds then ; abs , stability lights also show. Code remains c1155 : replacing abs sensor lead failed to cure problem -
what can I try next ?

 

Cleaning all the connectors for the abs sensors, both sides of plugs and connectors using electrical contact cleaner and a tooth brush.
The other thing is that the codes WILL NOT go away unless erased and the generic tool at your local parts store cant get the abs codes.
