🏷️ Basic Information

Make:

BMW

Model:

328i

Year:

2005

Chassis Code:

E90 (for 328i designation, though 328i wasn't specifically an E90 model designation in the US for 2005, it's more likely referring to the E46 generation 325i/330i which were current. However, the product name explicitly states 328i 2005, which is a common confusion point. For the purpose of this manual's coverage, it likely pertains to the E46 generation with a potent inline-six engine).

Engine Code Variant Association:

N52B30 (This engine was introduced in the 2006 model year on the E90 325i and 330i. For a 2005 model year referred to as '328i', it's highly probable this manual is covering the later E46 generation, specifically the 330i with the M54B30 engine, which was often conceptually associated with a '328i' type performance level in enthusiast circles. The manual might be mislabeled or cover a specific market's designation. Assuming the product title is accurate, it refers to a model variant of the E46 chassis, or potentially an early introduction of a later designation for specific markets.)

👋 Introduction

Positioning:

The BMW 3 Series (E46 generation, likely covered by this manual for the 2005 '328i' designation) was positioned as a premium compact executive sports sedan, renowned for its driving dynamics, sophisticated engineering, and luxurious appointments. It competed against rivals like the Mercedes-Benz C-Class and Audi A4.

Analysis:

In 2005, the E46 3 Series was in its twilight years, having established a strong reputation for sporty handling and performance. The 328i designation, if accurate for this year, would place it in a performance tier slightly above the 325i and below the 330i, or it could be a market-specific badge. The manual's comprehensive nature is critical for maintaining these complex German vehicles.

Features:

Excellent handling characteristics, powerful inline-six engines, premium interior materials, advanced (for its time) technology, and a focus on driver engagement. This manual unlocks the ability to maintain these premium attributes.
