This article has been around for a while but I've added some pictures and video. According to MOGolf, you can tell if the geared module is already on the engine because of a casting difference in the module.

These pictures show the difference.

There are currently 3 videos from me with another coming soon and a few videos from other people showing various chain noise and gear module conversions.

The second half of the article, repair procedure, has also been split off into a part 2 so that I can add pictures and more info later.

I believe sometime around 2005-2006, too late for the mk4 VW Passat TDI but I know from European Audi boards that Audi A4 had this problem so I put in a mention.

The new CBEA CJAA engine on the 2009+ Jetta/Golf use a geared balance shaft-oil pump module very similar to the upgraded part.
