Notes
  • →The nameplate in the engine compartment indicates which refrigerant has been used.
  • →The automatic transmissions have a extended oil filling. These transmissions require no oil change for their entire service life. The approved lifetime fluid must be used after repairs on the transmission or transmission oil cooler. The lifetime oil must not be mixed with or replaced by other types of automatic transmission fluid as this will cause transmission failure.
  • →BMW Part No. 83 22 2 365 988.
  • →Fill with water and - if required - with a washer antifreeze (according to manufacturer's recommendations). Mix the washer fluid before adding it to the reservoir.
