ABS pump module

Hi there, I have a 2008 Micra 1.6 active luxury, it has only done 13k miles, perfect condition, like new, but all the brake and esp warning lights came on, took it to garage, they said the codes indicated problem with the ABS pump, I called Nissan and they said they no longer make this part, looked everywhere for second hand part, cannot find one anywhere, part no. is 47660 BG04B, any ideas???
Is it worth taking pump out and sending it of to be repaired, no idea how much that would cost or if it would be successful, anyone know of how I may find this part, the cars way to nice to scrap. Please help, thanks :)
