Why is there a concern with chain stretch? Don't the tensioners account for any slack, and the VANOS accounts for any timing offset that might come with chain stretch? I'm pretty sure that's the case for the M54 engine, so why is the N62 different?

I did not deal with my oil pump chain at all on my M54, so I don't know about that one, but same questions.

^^^ Real questions here. I know the N62 is different in many ways, but still wonder why the things that make the M54 impervious to chain stretch would not apply here as well.
