Cannot reset oil life on 2019 C300 4Matic?

Asked by Mike Nov 12, 2023 at 07:24 PM about the 2019 Mercedes-Benz C-Class C 300 Coupe 4MATIC AWD

Question type: Maintenance & Repair

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?

If there is no information in the owners manual and you can't find anything online then the dealer will need to go in and do the reset. But you may have other issues going on with the menu.
