Brake pressure sensor failure is the good old bosch ABS Pump muck up, they all do it sooner or later, new ABS unit or ECM is required, however, it will pass MOT As luckly on these it doesnt bring the ABS Lamp on, but this year its all going to change, for now any other warning light is an advisory, soon it WILL Fail if any warning lights are on. but im not sure when, i seem to remember being april, so you might be better off getting it in for an early MOT or repairing.
I highly recommend BBA Reman for a new unit, you can actually remove the ECU From the pump so you can still use the car while its away for repair.
