Hey,

Just started my ML350 after it sat for a month (I was away) and it gave me a "-83d" code (if memory serves me).

It's under warrenty so I'm not concerned.... Just curious as to what it is.

Thanks,

I believe you are 83 days past when your scheduled service is due. The service can come up based on time if you aren't putting on a lot of miles.
