Change Transfer Box Oil:
• Run the "oil change" service function with the BMW diagnosis
system during the oil change to ensure that the VTG is drained and
filled completely.
Do I need special equipment for this or is this something I can do via Bimmerlink.
Thanks in advance! |
You're supposed to use ISTA to do it, it cycles the transfer case solenoids to empty it out completely and will tell you what to do after you fill it and at what temperature and stuff like that.
