Hi Peter,
you forgot the Blank:

In[1]:=computeIndividualCDOPLB[filteredTimes] :=
   Module[{i}, Print["computing IndividualCDOPLB"]; ];
In[2]:=computeIndividualCDOPLB[foo]
Out[2]=computeIndividualCDOPLB[foo]

In[3]:=Clear[computeIndividualCDOPLB];
computeIndividualCDOPLB[withAnArgument_] :=
   Module[{i}, Print["computing IndividualCDOPLB"]; ];

In[4]:=computeIndividualCDOPLB[bar]
From In[4]:="computing IndividualCDOPLB"
