Xhorse VVDI2 Asks to Disconnect Power Solution

 Problem: 

I just got Xhorse BMW BDC2 adapter for VVDI2. But have an issue. It asked to disconnect 12V power supply. Any help?

Solution:

Need adjust the adapter and fixing good and retain step number three directly.

NOTE: There is a Process wizard mode. The wizard mode is one-step process from the begining to the end.  If you choose wizard mode, don’t perform step 2, step 3… manually.

We suggest adding BMW BDC2 key with Key Tool MIDI or Key Tool Plus. KTP and MIDI don’t ask to disconnect 12V power supply.

VVDI Key Tool Plus Adds 2014 Audi A4 BCM2 Key with Audi BCM2 Adapter V2

 Tested the new Xhorse Gen2 Audi BCM2 adapter today on an encrypted 2014 Audi A4 (BCM2 8K0 907 064 JM).

Worked flawlessly. It was easy to place on pins, stable communication and completed full read of d flash and p flash with VVDI Key Tool Plus using the Gen2 adapter.

No need to write back service file. No need to remove additional components or use jump wires.
Highly recommend it for anyone doing Audi BCM2 jobs.
