Additional Notes
- The M3 variant across 2007-2013 runs a separate power steering system, meaning the power steering circuit operates independently rather than sharing fluid or components with another hydraulic system in the vehicle.
- The M3's power steering reservoir is capped with an ATF-type cap, indicating the system is designed around automatic transmission fluid specifications rather than a dedicated power steering fluid formulation.
- The fluid level specification for the BMW M3 power steering system is expressed as a range between a minimum and maximum mark, rather than a fixed fill volume, which is characteristic of a service top-off or level-check procedure rather than a measured capacity overhaul fill.
- The use condition recorded for the M3 power steering specification is normal, meaning the fluid level guidance applies under standard operating conditions rather than a severe-use or first-change-only scenario.
