Additional Notes

  • The BMW 6 Series E63/E64 635d covers model years 2007-2011 with a separate power steering system that uses an ATF-capped reservoir, meaning the fluid type is automatic transmission fluid rather than a conventional power steering fluid.
  • The capacity specification for the 635d is expressed as a fill range between the minimum and maximum marks on the reservoir rather than a fixed volume, which is characteristic of a top-up or level-check service rather than a full system overhaul fill.
  • The specification applies under normal use conditions, meaning the interval or fill guidance is not adjusted for severe driving cycles, extended idling, or other demanding operating environments.
