BMW had a problem adjusting the mileage. After inserting the analog chip and ID7 filter, a red dot appeared on the dashboard and a DTC appeared on the diagnostic tool.
Solution:
Red dots are generally caused by the chip ID not being written, and you need to use Yanhua YH35XX Programmer.
What needs to be noted during operation is that the data and ID are read together on the YH35XX Programmer software, and then both data and ID are written to the chip.
