Additional Notes

  • The BMW 3 Series Convertible E93 328i variants, covering both the N51 SULEV and N52 engines across 2007-2013, share an identical automatic transmission fluid capacity range of 9-10 liters. A capacity expressed as a range rather than a fixed value typically reflects the difference between a drain-and-fill service and a full overhaul or replacement that includes the torque converter.
  • The 9-10 liter range on the 328i N51 SULEV and N52 contrasts with the fixed 9-liter figure on the 335i and 335is configurations. A fixed single value generally indicates a more consistent fill volume across service types, or a specification tied to a specific procedure.
  • The 335i Convertible was available with two different engines during the E93 generation: the N54 twin-turbocharged inline-six covered 2007-2010, and the N55 single-turbocharged inline-six covered 2010-2013. Both share the same 9-liter automatic transmission fluid capacity and the same 100,000-mile change interval under normal use conditions.
  • The 335is Convertible uses the N54 engine and carries the same 9-liter automatic transmission fluid capacity and 100,000-mile normal-use interval as the standard 335i configurations, despite the 335is representing a higher-performance trim level.
  • A 100,000-mile change interval under normal use conditions applies uniformly across the 328i, 335i, and 335is Convertible rows. Normal use conditions in transmission service contexts typically exclude frequent towing, extreme temperatures, or stop-and-go driving patterns, which would fall under severe use classifications.
  • The M3 Convertible across 2007-2013 is specified with a semi-automatic transmission rather than a conventional automatic, and carries a 7.8-liter fluid capacity. Semi-automatic transmissions in this context refer to automated manual units, such as the BMW M DCT or SMG, which use a different internal architecture than a traditional torque-converter automatic, accounting for the lower fluid volume compared to the other E93 rows.
  • No fluid change interval is listed for the M3 Convertible semi-automatic transmission, whereas all other E93 rows in the specification carry a 100,000-mile normal-use interval. The M3 row contains only a capacity figure of 7.8 liters.
