Hi.
I have VWZ1Z7 (1K0 035 198 B) and I've tried to read FIS using the method from this article.
As I know the 20, 40, 60 lines of a dump must be the same. But I had only about 1 second after pushing on the "on/off" button for reading and each time i've received different data. Also i've tried to lower the voltage to 7.5v. But in this way the mfd2 just has been switched off.
I've found some information and now I'm not sure about the right connection. Should I connect 5v instead of GND to the point 3?Connection.jpg

I don't have A4 cable. I've used a CH341A programmer and the connection scheme according to the picture. read.jpg

Did you connect GND from programmer to radio board?

[ArtemK]

Yes. Connection.jpgprogrammer.jpg

Also I've found this picture. Where is the true?

Sorry, I forgot that I had checked the contact 3 on the board by a tester. Definitely it's GND.

Do not connect 5V. Connect 3 x 12V to radio factory connector.

Hi.
Eventually I've read the FIS. My problem was that I've used too long wires for I2C.
Please, help me with decoding.
