Usually just a bit of love and care , no hardware. That car stills need a new one from VW though and once intalled and configured it will appear to have the same vin and other data too- essentially it will be the same ECU as before. With your hand controller I don't think they are too fancy either so it may not store flash counter values and you may simply be able to load it again. You shouldn't have to pay for this as the same file that what used before would would work but there may have to be a tiny but of effort at their end if something needs to be reset perhaps
Did you see what errors where showing in the engine module before it went to VW ?
