Just got done changing the oil on the S500 and figured I would take a look at the diagnostic LED to see if there were any stored codes.
My particular car is a transitional model as it still has both the 38 pin diagnostic connector, the single diagnostic LED, but no OBDII connector. There is a cutout in the bolster under the driver's side dash for the OBDII connector, but it's not punched out and there's nothing behind it.MY 96 is when they started using OBDII, and from what I have read MB was not keep about adopting it, so they were a bit of a holdout in this area. You can use an LED with a current limiting resistor and a momentary pushbutton to read codes directly out of the diagnostic socket, but it's a PITA in my opinion. The single diagnostic LED give you a global indication of codes but only shows the main ones and not codes unique to certain modules. Anyway, I ran the diagnostic procedure on the diagnostic LED and...... voila! No codes stored. Same as it was when I got the car. Amazing how complex these cars are that it's gone since February without throwing even one code. Nice. I really like the W140...
