A single beep from the horn
I just got my 2000 ML320 about 2 weeks ago and right before I start it the horn would beep. Why is this? It has 52,100 Miles on it and on the meter it reads -4100 If this is not good. I guess I will be going to the dealer this weekend.
buy a Hi and Lo Note it cost less than 50 bucks/set

You should go to a dealer and ask them to reset your maintnence computer. It will beep after your service post due. So it should take no more then 1min for a dealer to reset. It not your horn it your computer makes sound.Good luck with your ML.:p
