Jack, I know the VAG is some kind of sweet tool. And I know that is what this forum is about not scopes.
And also I know a guy like you and the team from Ross tech can probably tell what is wrong before opening the hood, I call this empirical studies, experience, just is what it is.
But with an engine as complex as this, would have done a relative compression and compression wave form back about page one before buying a butt load of parts. As. You note all the lines might look sweet but what if a keyway or other is compromised now what do we trust.
As you stated with no codes has somebody played with it?., I hate it, makes it really tough for the garage guy when trying to trust the scanner data.
Again great stuff, have a great new year.
