Cannot reset oil life on 2019 C300 4Matic?
I just completed an oil change on my wife's C300 that we purchased used,
when I try to do an engine oil life reset using my scanner, it tells me this
function is not available, also on the scanner, service items also come up as
unavailable, following the instructions found here and elsewhere about how
to reset it using ASSYST PLUS through the dash menu, instead of getting a
menu item for FULL SERVICE, it immediately shows message of service
overdue. How do I reset the oil life when ASSYST PLUS is unavailable?
