You buy the main unit of digiprog 3. Only has ST01 and ST04 cable in the package. Different car type need different cable. Such as your car mode is BMW 7er CAS E65, you need to move the chip from the main board. Then use cable ST63 connect the chip with your digiprog 3. Do not directly use the cable connect with the board. Then you can read the write the mileage. So your problem is that 1) you do not have the right cable. 2) You connect it in wrong way.
