No question the O1E is strong, but that does not mean that its the only choice.

Agreed. However I have a 01E out of B6 a4 3.0 it seems to have the updated collars in it which is a good sign. I've had 3 of these open so far all from 3.0 B6's and all seem to have the updated collars in them. Not sure if that's how they came but also good to know.
