ABS,DSC & Warning Lights..PROBLEMS

[samsx5]

Hi Everyone,
I have an X5 2000 4.4i Sport that has just developed a problem. When started from cold on a morning, reversing off my drive all I hear is a type of grrrr noise and also the ABS sounds like its operation and all the lights come on the dash. The lights usually go out after I pull away. Today they came back on while driving at about 90mph and the warning light was flashing amber/red/amber/red in 1 second sequences. The lights stayed on until I turned the ignition off. I am getting concerned with all these lights on my dash. Please help if you can.

Thanks, Tony
