traction control warning light

[retna]

Just got 182 back from mot where they changed track rod end and my abs/traction control light and service light come on 30seconds after I turn the ignition, Any ideas?

wouldn't have passed with the lights on so may have got some oil on the abs ring or sensor. They have a habit of disabling the abs/esp if the system malfunctions in any way i.e. dirty sensor/ring -> unable to read -> system doesn't work properly….
Jack it up, spin the wheel and see if its all clear -if not give it a clean and try again...
