Hey I started my 01 ML and it gave an extended tone along with a maintenance code 300 appearing in place of the miles that I have on the vehicle. This happened after I started the vehicle, and turned it off because I left something, changed my mind about getting it and started it right back up after about 20 seconds. However the code is still there for the second day. I am thinking this may have caused the error. Maybe? Will it just go away?

Does anyone know what this code means?

Thats what it is man. Figured it out today. It went from 400 to 300 and now 200. I talked to a friend with an ML. Thats what it is.

Thanks for the confirmation!

I realize these kind of things may be common since to most on this forum, but hey I bought my ML last year an 01 320 with 36000 miles and I have only put around 7k miles on it. Second owner, no problems. So I am still learning. The dealer didn't tell me much about how the insruments work. Thats the main reason why I love this site! Lots of info!
