I've been driving the D3 today, and no problem to report with the ABS until whilst sat idling outside my house doing 0mph the fault triggered.
Tomorrow I am going to hook up VCDS and connect to the ABS controller and look at measuring block 1 which should show me what all 4 wheel speed sensors are seeing and then start a log, and hopefully when the fault recurs I may catch something in the log.
I may even try going for a drive to see if that sensor is returning consistent readings compared to the other three sensors.
The attached picture is taken looking up at the sensor with the wiring disconnected, no sign of water ingress at this end.
