Summary Verdict

The 2002 BMW 330Ci (E46) is a desirable performance coupe with a generally solid mechanical foundation, particularly its M54 engine. However, as a vehicle approaching two decades old, it is susceptible to age-related failures. Common issues revolve around oil leaks from gaskets, cooling system components, and the VANOS system. Transmission reliability is good for both manual and automatic, though wear items like clutches and potential leaks/torque converter issues in automatics should be considered. Suspension components, especially control arm bushings and rear subframe mounts, are known wear points. Electrical gremlins, often related to the BCM or ABS/DSC module, can also arise. Interior issues like pixelated displays and sagging headliners are cosmetic but common. Regular maintenance and addressing these known issues proactively will contribute significantly to the long-term enjoyment and reliability of this classic BMW.
