E63 Engine Issues
These are software issues, minor air leaks in the intake manifold, oil cooler hose (ML63 only) and a few have reported lifter noises (haven't seen any myself).
Considering it's a completely new engine of such a high performance level, it is pretty reliable (as it should be!)
Any internal engine wear issue (especially cylinder bore wear) is extreamly uncommon for any MB engine. I'd be interested to know the outcome of your problem and see any pictures you may have.
