Thanks a bundle for the replies and information! At the concern of me breaking something, I will probably end up letting my "indy" Mercedes shop do this work on the odometer. I dont think he would charge to much to do it.

I am not sure about the warning lights, why some are brighter than others, but I know that my 1984 190D and 1985 380SE were identical.... some warning lights were quite dim and dimmer than others. It may be normal... maybe someone that bought one of these brand new or have one thats still with ultra low mile and new mint condition may have more info on this?

Thanks again!
