I've been working on this problem for a while. My data table looks like this
(the actual table has approximately 5000 rows and for a given ID/Engine
Combo, can have as many as 300 codes that need to be concatenated.

ID Code Engine
BOX050 W3 1
BOX050 F3 1
BOX050 Y0 1
BOX050 A8 1
BOX050 B9 1
BOX050 K0 1
BOX050 K2 1
BOX050 T1 1
BOX050 X2 1
BOX050 AP 1
BOX050 D5 1
BOX050 F6 1
BOX050 G9 1
BOX050 GE 1
BOX050 K3 1
BOX050 L3 1
BOX050 MF 1
BOX050 N7 1
BOX050 N6 1
BOX050 U3 1
BOX050 AK 1
BOX050 BD 1
BOX050 BH 1
