I've got the first one in for an injector leak which was just starting to build up the nasty black stuff. A little Kroil and running it to soften up and it came right off.

I just performed an oil change on my daughter-in-laws 06 CDI with 282K on the clock. I do always check the injectors for black-death symptoms at every oil change and it was A-OK again. Since the plastic covers can be removed in about 30 seconds I don't see it as a big deal to leave them in-situ. Agree with catching it early and Kroil, I've actually participated in a fairly advanced case of black-death on an 05 CDI and it wasn't really all that difficult/expensive to fix. Just a bit tedious.
At 282K the SBC is original and I continue to be amazed at how leak free the engine is, its actually totally devoid of any leaks at all. The OM648 doesn't have a dipstick but this specimen doesn't seem to consume any oil between 10K interval changes.
The contrast between my experiences with the OM61x and the OM648 is quite stark. From where I'm sitting the OM648 wins hand-down in the long-term reliability test.
