How do you clear code wait after entering the wrong code three times on ML 350?

Answer 1

Disconnect the negative battery terminal and wait 5 minutes. It should say code after 10 minutes with the key turned into the number 2 spot. If you don't have the radio code for your radio, it can be found on the radio itself, remove the radio and look on the side of your radio it is stamped into the metal and is a long number usually starting with 2 letters. The last 7 of the numbers is what you give the dealer when you call. Most people give the serial number and the code you get from the dealer doest work, this happened to me. I finally got the right code from the longer number on the side stamped in the metal. If you try your code and it keeps flashing that's not the right code. When you type the right code in by using the number pad... And then hit the seek arrow it will come on fast.... I hope this helps anyone. Instead of just saying call a dealer haha
