P0500 speed sensor joy

Well after an interesting drive with the rev counter and speedo turning on and off, various warning lights doing a disco effect (abs, tc, HDC, mil) and F4 limp mode every now and then just for a laugh
Got the car home, but had to switch it off a few times. I now have P0500 vehicle speed sensor, which is more than likely an abs sensor fault. Hopefully it's not the one in the autobox
Anyway, the point is, which one?
I was thinking of replacing the two front ones first, then the rear ones if this doesn't sort it.
But if anyone has a trick for testing the sensors, please let me know.

Cheers
Mike

If there were problems with the ABS sensors, you would surely have ABS codes saying which sensor is at fault.

Nope, couple of CAN bus errors and P0500.
