Could someone point me to the instructions for building a code reader for a '91 190E and a list of codes? Thx!

Hi Jim. Did you ever find where to read the flashing codes and code list? I too have a '91 Mercedes 190E 2.3 (Canada) and have no clue where to read these codes but i do have a couple service manuals.
