I have the maxisys ms908p which is up to date and I can do bmw control unit software updates no problem at all. Every time I try a mercedes the control module software numbers and the reported update software numbers are always the same. I've had several mercs that I would like to carry out software updates on but haven't been able to and have been unable to find any info on this. Has anyone had this before or knows what i'm doing wrong?
Thanks
