Hi,

Out of curiosity, does anyone know if you can access some diagnostics through the instrument cluster of a 1997 s420? I read that you depress a tiny button on the clock stem and then twist clockwise. This only seems to adjust the clock when I tried to do it.

Thanks,
Brian

There are not any diagnostics in the cluster on the '97 W140 just mileage. What are you trying to find?
