Build the scanner tool, and interrogate further.

Arthur's scan tool: http://members.aol.com/ajdalton7/ledtool.jpg

JimF's site to give you some insight as to what the codes mean:http://pages.prodigy.net/jforgione/MB_S500.html (see the Diagnostic Module code - section 6 for current codes)

Radu, if you hear a buzzing from behind the battery I'd suspect a bad OVP relay.

You have an EGR problem. Do a hand vacuum test at EGR port at idle and see if engine attemps to stall. First Suspect on 104 is blocked EGR tube at head.
Search EGR..tons of info on this common code.
Recheck pin 8, as you also have an Ignition code

What do you mean by hand vacuum test?... I guess that I will read the posts first.
Did recheck pin 8 got code1
Also my ASR problem reappeared even after I change the brake light switch.
and I got now codes 2 and 14 at Pin 14.
Maybe those defects will correlate somehow.
In other order of ideas, the car runs beautiful no smoke, no MPG increase, clean tailpipe, and plenty of power. The only think that bothers me is the crazy ASR and Engine light.

Indeed there is a buzzing noise that I hear if the engine is ideling and a/c and radio are off so I could differentiate the noise. So I should go for OVP relay.
But I have no other typical symptoms for OVP. Are you sure?
