Transmission Automatic (S5)
The 2004 BMW 330I rides on the E46 platform with a five-speed automatic transmission (S5) and returns EPA-rated fuel economy of 17 city, 25 highway, and 20 combined mpg, while its engine requires 6.9 quarts of oil meeting 15W-40, 10W-40, or 10W-30 API SJ specifications. Across the model's 1999–2011 complaint history, the 2001 model year recorded 121 complaints — the only annual figure cited as both the highest and lowest — placing the 2004 iteration in a dataset where reported issues appear concentrated in a single early year, suggesting a maturing platform by this model year.
