Changing the drive-unit reduction gearbox oil at the 40,000 km service is a huge plus—keeps the reduction gears quiet and clean for 300,000+ km.

@DominicWilson Thanks for posting the exact numbers—bookmarked this thread for my upcoming service.

@CanBusHacker Good tip—also worth keeping a compact 12V lithium jump starter in the frunk rather than the under-boot floor so you can always reach it if the electric tailgate loses 12V power!
