There is something wrong with my CGDI Prog MB. When I use it to add new keys on my Mercedes ML2013 and W906, a pop-up window displays an error message ‘The current voltage is insufficient: 2.12V, please charge the vehicle or switch on the 12 V power supply.’ I have checked the connection, and the CGDI MB has been connected to the car via obd, and connected to the laptop via usb cable. Why is the voltage still low?
Cgdishop.com chief engineer replied:
You need to provide the 12V power by an extra power adapter.
First connect the 12V power adapter to CGDI Prog MB Benz key programmer
Then connect the device to your car and computer
Finally, run CGMB software to add new key to your car.
