dsc, handbrake and tyre pressure lights

Hi all , I have a 2006 e46 320cd and yesterday dsc, handbrake and tyre pressure lights came on at the same time i haven`t drove the car for 3 weeks as i was o holiday and i was thinking it might be because of that , but this morning when i turned on the ignition all three lights came on again , drove it for a while and noticed that the abs is working break pedal seems as hard as it should be, checked the break fluid seems fine any ideas ???
