Today we have a 2008 Mercedes S550 that the customer said the cluster stopped working. They went to Mercedes and they said it would be $3000 for a new cluster but there was none availible so they put a used cluster in then said they could not program it. Let's try to fix the mileage on the new cluster and see if we can get the correct mileage to display. Currently the car just shows dashes for the mileage.
