Right then.. so after all this, in the spirit of repairing not replacing, I took the cover off the relay and the thing was full of dust and C###. So cleaned up the contacts, sprayed with contact cleaner and put back on. All works now, brakes function, abs comes on ( really hammered it and abs definitely came on) and no buzzing or pump over running.
I know there will be many drawing of breath and tutting, but I took the chance and so far.. working. I wouldn't do it to any one else's vehicle, but on my head be it. Ready for the onslaught..
