The Mileage Blocker unconditionally removes the mileage. The mileage figures will remain unchanged even after removing the module from the car. You can use our Mileage Blocker to alter the mileage and remove it anytime. Stopped mileage will not increase spontaneously after removing the module. However, in most cases, error messages should be deleted after removing the tool. Can Communications save any interruption messages as error messages. These are sporadic errors that do not necessarily have to be deleted, but it is recommended.
