Re programming ABS Module

[czm]

Hi there
I started today replacing the ABS Pump/Module on my wife's 2010 A3 1.6TDI sport back.
According the Audi dealer the fault log showed that the ABS module was faulty and wanted a fortune to replace it.

I found a used OEM Pump and Module and fitted it today, bled the brakes ect however I have not cleared the old fault codes so still get the flashing dash lights.

I understand that the new pump/module needs to be reprogrammed with VCDS however I am unsure on how to do this- any body point me in the right direction??

Thanks
