One customer gave feedback that Xhorse VVDI PROG will not read anything from Audi Q7 steering lock but said “adapter wrong” when trying to read old unit.
Here Xhorsevvdi tech answers
The adapter in picture is only for ELV emulator.
To read/write original ELV module, solder or use correct ELV adapter (Xhorse XDNP45 Adapter)
Hope this could help!
