The only way the engine code would indicate that the car carried the last design bearing would be if the engine number contains the letters "AT" and the engine number itself decoded to being a 2005 or later engine. AT means the engine is a replacement, all of which after 2004 are the last design bearing.

Just be aware that (1) Porsche never retrofitted an engine with an aftermarket IMS bearing, (2) As I mentioned above, the final design bearing fails just like the earlier units, and (3) The only IMS bearing you don't have to worry about is one that has been retrofitted with an LN Engineering replacement.
