As Mr Goonery said, its one of the ABS sensors most likely causing the problem.
There's one sensor on each corner of the car, and it sends info to the ABS, Traction, and Runflat systems, so throws up all the lights at the same time.
Dealer diagnostics tell them which sensor is the cause, its a relatively cheap part, and shouldn't take them long to fix
Sensors can be dirty, or can be a bad connection, but dealers will just replace the part as its relatively inexpensive.
