My 1999 E300 diesel has started giving me warning messages on the dashboard display suggesting "service due in 27 days". One day is subtracted from days remaining each day.

I did an oil change back in Decemeber with a 229.5 compliant engine oil and reset the FSS system at that time. It appears I will be at 0 days at the end of June which would coincide with 6 months having passed. I checked the OM and find several non-specific references to this message. I am not clear on what's actually due, if anything. The car has been driven ~3,000 miles since that oil change.

Is anything actually required when the day countdown hits 0?


Thanks.
