I think part of the confusion is that document is for BMW North America. Maybe outside of NA the BMW G series 330i is made with the B48TU?
Couple of questions for you:
- Is your 330i the new G series, or old F?
- What is your manufactured date?
- How do you know that your engine internals are the same as the B58TU?
Thank you, we are getting closer to answers.
