My friend just bought an 04 E60 530i and he told me that when he does a slow acceleration from 40-60 mph, there's a hesitation. But when he floors it, there's no problem...
Does anyone know a possible cause..??

tell him to get heavier shoes

Could be many things. Have him take it in and see if a newer software fixes the issue

change spark plugs
