Problem:
I used Yanhua Mini ACDP 2 to reset the mileage of BMW 535i GT, and encountered trouble when making log data. Some people told me to wait when making log data, but I was still making log data after 10 minutes. Is this normal? And what makes me curious is that the prompt that ECU needs to be upgraded appeared on the interface. Should I upgrade the ECU?
Yanhua technicians answered:
This car was produced in 2010 and is an older model. It is recommended to remove the dashboard for CAS matching.
Regarding the question of whether to upgrade the ECU, there are risks in upgrading, and after the upgrade is completed, other equipment is required to set parameters or functions of the ECU to match the original vehicle system.
