Hi Dave GSXR--The scan tool I bought only works on ODB II (model year 1996-now). It will not work on the W124. I was mostly responding to the original poster whom has several cars he keeps that the ODB II scan tool will come in very handy for.

I'm embarrassed to say I've never pulled the codes on my w124's. There is plenty of info on that process on this forum.
