If a Masbooq commits an error whilst behind the Imaam, should he perform Sajdah Sahw?

Answer

There is no Sajdah Sahw for the Masbooq (late-comer) if he commits any error whilst behind the Imaam, i.e. before the Imaam has terminated the Salaat. Thus, if in the Imaam's last raka't, after Tashahhud he recites Durood Ibraaheem, Sajdah Sahw is not necessary.
