I had posted a thread before asking about a speedometer problem and someone suggested I may need to replace the instrument cluster. I know this is probably a silly question, but I am concerned about the legality of this. I know when I have gone to the dealer they have recorded the mileage and I don't know if they'd say something to me if the mileage was drastically different. I don't have plans to sell my car but I don't know how selling a car with a changed cluster would work, as tampering with the odometer is illegal. Can anyone shed some light on how this works?
