    would I be on the right track thinking they have broken a sensor or cable to a sensor

    what warning lights exactly? abs? traction? esp? brake pad wear?

    might have damaged an abs/pad wear sensor.

    speedo is driven off a sensor on the gearbox tho. dunno how they might have managed to damage that changing wheel bearings.

    take it back and complain. get them to code read it etc.
     
  4. Damaged speed sendor I would say, not 100% here mind, but ABS, ESP and speedo all rely on the speed sensors for their readings.
