Problem: Tried to read 2015 Audi q5 BCM2 with the new style Audi BCM2 adapter v2 and vvdi key tool plus . The device ask me for 12v power supply. But the new adapter does not have orange bcm2 adapter, thats where you plug the 12v. Error: 12V unconnect ot adapter connect line error. use DB15 cable. Solution: You don’t need any other adapters, only this cable to adapter and tool. Voltage comes from tool to adapter. If need, you can put charger cable normally to keytool plus. Those new version adapters works only with keytool plus and multiprog . This one don’t a 12v power it just plug and read. This is a version 2. Because new Audi BCM2 adapter does not need nothing between tool and bcm2 adapter. You need only this cable between adapter and tool. Update your tool and use the correct menu option . There is an option that says ‘Adapter new generation’.
