Disco 1 abs problem no codes

had an issue with the abs air gap front left found play in swivel hub but now fixed but the abs keeps coming on at slow speed but the warning light stays normal like its all ok(apart from my pants) and no codes.any idears?.

if the warning is not on it's normal to not have fault codes, it might be an air gap difference between hubs, not as large to trigger a fault code but enough to give different reading on that side then the system will act like that wheel is slipping and activate ABS, try to tap a bit the sensor and retighten the retaining screw...the only certain way would be to plug in a dedicated tester and read live sensor outputs to see if they are even at the same speed or not

ok thanks i will give that a go.
