Brake system failure

My Evoque has just made a clunking sound which I felt through the brake pedal and now my power steering has gone, all warning lights have come on saying parking brake fault, hdc fault drive carefully abs system fault, my reversing camera won't come on and my speedo and rev counter won't work

I'd guess a CAN bus/Device Failure, will need proper Diagnostic tools to diagnose it correctly.

There were issues with the rear camera taking out a CAN bus in the early models due to moisture ingress.
