I have a question for everyone. I just bought a 03' ML350 Inspiration package yesterday. On my way out of the dealership I noticed that there was a double wrench code that appeared on the display. At first the code was double wrench 400, the next time I started it I got a double wrench 500. The salesperson was not sure what the error message was (of course) but said that he would find out. The car just went over the 60K mark so I was wondering what types things to look out for.

Thanks for your help.
