I've always kind of wondered how in the world a mechanical linkage that is supposed to adjust the pitch of the blades in a turbocharger could possible live for more than about 5 minutes in the environment where its constantly getting pummeled with high-velocity exhaust gas. I'm amazed this is the first time I've ever heard of issues with the associated linkage.

There was nothing broken I guess? What are you impressions about the long-term durability of this kind of setup?

I've got lots of OM648 CDI experience but I've never had to mess with any turbocharger issues, I was aware the OM642 had the variable pitch blade setup - do you know if the OM648 has the same setup?
