I have a e320 1995,that has a surging idle and eventually will surge and die at idle,cold.I used the 16 pin connector next to the battery with the push button to read the codes.If I press and hold for 2-3 seconds the button,the LED will blink 10 times,then press again will blink 16 times,then again 24 blinks,what are those codes and how to erase them first,then read them again?,car had a dead battery and I just want to erase the codes,drive the car and then read them again to start and diagnose the idle issues.Any help will be appreciated.
