Yes, I bought it for my 1998 E300 that is OBDII compliant and which turned out to have a defective MAF sensor that caused the check engine light to come on. I was disappointed that the software, which included a dynometer and other performance monitoring functions would not work but I still was able to fix the MAF sensor and reset the light so it was worth $90 to me.
