Another week later I get an anti-skid message, that disappeared a few minutes into the journey and on return it never popped up.
Last night, well it was Blackpool illuminations on the dash.
Almost all lights came on, a message about brake failure and to stop carefully. I didn't think to take the picture of the dash.
Anyway pulled into layby and stopped fine. Tried to turn engine off and the key didn't completely free itself in the lock, it was sort of locked. Started the engine and it started fine but again some lights but not all, and also the windscreen wipers started moving without engaging them. couldn't even turn them off. So after a few minutes of wishing and hoping the wipers turned off, I turned the enigne off, was able to remove the key. Rinserted and restarted the car, and all lights back to normal, reached home without any further issues.
Done a multimeter test on battery and I get 12.28 engine off, at idle I get 14.69 and loaded up with aircon/fans and lights etc I get 14.66.

Not meaning to hijack this thread but is that battery or alternator? From my brain cells levels and google searches, it looks like battery should be replaced.
I have no records of when the battery was last replaced.

The voltages you quote there are perfectly acceptable both off and on charge. In fact to only have a drop of 0.03v when on full load is really rather good.

I would suggest both your alternator and battery are fine. I know that does not help you a great deal, but I would guess your issue is elsewhere unfortunately.

It is like a copy of my problems I had. What I did and got rid of them, was: EGR/CEM removed and cleaned, no more messages.
In my case anti-skid message was EGR related, and wipers bad CEM connection.

OK, I was hoping it be a open and shut case...
Ah well, I'll try and give the CEM a removal and clean.
