I have a customers 2002 E320 sitting here in the shop. I replaced the intrument guage cluster, and have been able to set everything EXCEPT the odometer. It simply reads ------- (dashes) across the screen. Anyone perform this repair ? Know how to get in there and fix it ? Seems like its not through the scanner ? I know the previous model, you did it inside the car, that doesn't seem to work either. HELP !
