Yeah, I have always been something of a oem part researcher; going back to my aircooled vw days, I was always trying to get the best and correct parts, for my Volkswagens. Once, my New Beetle went out of warranty; I was thrown into a totally different world of oem parts suppliers and it took some time, effort to attempt to figure everything out.
I was amazed, to find Schaeffler, to be a major player in the German auto and VW oem parts supply chain. Over the years, it seems; they have created or supply some pretty interesting technologies, which many could say, they love or hate!

Things like cage-guided needle roller bearings, diaphragm clutches, dual mass flywheels, alternator clutches, etc.

As I ended up needing to replace various failed parts on my New Beetle; it became readily apparent, that many were supplied by the companies in the Schaeffler Group. e.g. INA, ***, LUK and Ruville.
Things that I had to have replaced; that were suppled by Schaeffler companies, were typically motion related: serpentine belt tensioner (Ruville), alternator clutch pulley (INA), timing belt kit (Blauparts/INA), wheel, transmission bearings (***) and clutch/flywheel kits (Luk).
I'm glad Luk was able to help, they were also very professional and helpful with me as well. I have found the REPXPERT support site; to have solid tech info and even, repair training and various types of support info for installation of their products. One particular things I learned; was a tech bulletin, about NOT doing a bleeding process, before installation of the slave clyinder, on the 02M tranmission. Many try to bench bleed these; before they install them and as the tech bulletin states, it destroys the assembly. I was glad I saw that and made a point; of bleeding after installation and used the Phoenix Systems reverse bleeder with excellent results.
