BMW 3 series, E90 / E91 / E92 (EU)

Power steering fluid capacity & service interval

BMW 3 series, E90 / E91 / E92 (EU) power steering fluid capacity is between min and max. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
  • M3 CRT (2011-2012)
  • Separate system (ATF cap)
  • Use: Normal
  • Between min and max.
  • M3 GTS (2010-2011)
  • Separate system (ATF cap)
  • Use: Normal
  • Between min and max.
  • M3 (2007-2013)
  • Separate system (ATF cap)
  • Use: Normal
  • Between min and max.

Additional Notes

  • The BMW 3 Series E90/E91/E92 M3 (2007-2013) runs a separate power steering system, meaning the hydraulic circuit is independent from other vehicle systems rather than integrated into a shared fluid loop.
  • Across all three M3 variants listed, the specified fill level is expressed as "between min and max" rather than a fixed volume, which is characteristic of a top-up or inspection-based service rather than a measured drain-and-fill procedure.
  • The M3 CRT (2011-2012) and M3 GTS (2010-2011) share the same separate-system architecture and the same min-to-max fill specification as the standard M3, despite being lower-volume, higher-specification derivatives.
  • All three configurations carry an ATF cap designation on the power steering reservoir, indicating the system accepts automatic transmission fluid rather than a dedicated power steering fluid, which is a relevant compatibility detail when sourcing the correct fluid type.
  • The use condition recorded for all three variants is normal, meaning the min-to-max fill specification applies under standard operating conditions rather than a severe-duty or first-change scenario.
