The wiring in that area in general is known to suffer, usually bad connectors but also wiring itself has been found broken, tis very much trial and error though

The said wiring does roughly a 90 degree turn towards the middle of the car before disappering throught the bulkhed etc. The -shudder- of the diesel can over time cause a break in one of the wires just at the 90 degree point (from the horses mouth aka Corin

)

Just to clean this up.

The ABS fault was due to a broken wire on each of the front sensors somewhere in the loom.

Thanks for all your help.
