Service Code
3 Answers
There is a "Service A", but the display should show a number ( like 1,2,3, etc.) and mileage after it. Are you sure it sys "AM exceeded"?

I got the "Service AM Exceeded" message on my wife's 2010 GLK. The Google has no answer. I'm pretty sure it said "Service A" first and now says "Service AM." Taking it in this weekend, not sure what to expect. Will try to remember to follow up here.
Shop didn't have a clear answer, the mystery continues.
