Recently took my 06 JCW S in for the factory 20,000 mile brake service and about 400 miles later the ABS and traction control light come on and stay on when the vehicle starts up about 60-70% of the time. Has this ever happened to anyone? Could it mean that the pads are due to be swapped out?

 

Is there a third light also lit up? The tire pressure light? Common failure is the wheel speed sensor (mine was corroded) and I've included a link below:
