E46 Generation:

328I Positioning:
The 328i was a popular mid-range engine option in the E46 lineup, balancing performance and efficiency.
Production Years:
The E46 328i was produced from 1998-2000 in Europe and 1999-2000 in North America. The 2002 model year 328i refers to a specific variant within the E46 lifecycle, likely a placeholder or a specific market designation if production of the 328i nameplate extended beyond 2000 for certain markets. For North America, the successor to the 328i was the 330i with the M54 engine for 2001+ models. This manual likely covers the M52TUB28 engine specific to the earlier E46 years or a specific regional variant. (Clarification on the exact engine code for a '2002 328i' would be crucial, as the primary US 328i was phased out for the 330i for 2001. Assuming this manual covers the M52TUB28 for a specific market or an error in the model designation).
