Phantomlord, you and Misha are "The Man" !
This is just what I've been looking for!
I've been limited to the blink codes until now and have been craving for more information like this..
Now, one question you or Misha might be able to answer;
I'm currently building a K-line interface (to RS232)
http://www.skpang.co.uk/content/view/18/36/
Would this be able to talk to "HFMScanner" directly?
I have one 1995 E220 (111.960) and one 1995 E320 (104.992), both with the 16-pin diag connector. If I understand this correctly - you hook up pin 1+16 for power supply to the interface and the "K-link data signal" to pin 8 (HFM) ?
Just simple as that?
Just dying to get this to work!
Best regards,
Lars.
