Xhorse VVDI PROG can now be able to read Volkswagen MQB D70F35xx on bench successfully. Need to buy MQB Software License at first, disassemble MQB board from vehicle to lift pin or cut wire for connection. Wiring diagram can be found in VVDI PROG software.
As you can see, I've finished the connection, VVDI PROG is reading the D70F35xx IMMO data. It's in the process of reading. This may take some time to read the processor, probably 5 minutes, just wait for it... After successfully reading, I can use it to add a new key with VVDI2 directly.
The new feature was just released last month, so I'm still testing. But everything worked out for the first 3 cars. This is the 4th car. It's okay to believe it.
