Prolly tried this already, but as insane as it may sound..
have you cleaned your ABS sensors?
I had this for ages on mine - and it only buggered off once I cleaned all the bum droppings off my front offside ABS sensor & sprocket when I replaced a split boot..
I know it was the front on mine - but it might be worth look..

^This
Worth a punt first. A crappy connection on the sensor, or grease from a split gaitor going all over the abs sensor, had that on mine once years ago.
Only 'true' 4WS issue I have ever had was the dry solder in the ECU, and that was after 11 years of driving it.

Well I did have an abs fault which was ns front sensor. I have now replaced this but 4ws fault cropped up again. Will try cleaning the others also and see how we go.

Front abs sensors aren't connected into the 4ws system at all though? It only takes a speed signal from the rear ones?
