SOLVED

after trying countless solutions and checking abs ecu
and removing complete engine to instrument wiring loom and Can twisted pair half a dozen times
( pictures later ) I found the devil hiding away in a little green wire
about six inchs from the abs ecu plug wrapped inside the twist was a pin hole no or visible break whatsoever just a tiny hole probably 0.25mm.
I cut the piece out and rejoined all good now everything works

Conclusion

I nearly ruled out can wires as tested with test light but after checking all other possibilitys knew it had to be a break I had already checked them few times so as loom was out I checked again a inch a time under a bright lamp and found it fixed and coded complete system on my living room floor lol.

worth noting is that immo/service light will be completely gone non appearing for this fault , the light will come back when wires fixed and ipc may play up and not program till fixed also.

i will tape up can wires separate and then tape them into loom for added protection so it shouldnt ever happen again.
