This software works on my S4 B5 with stock 8d0907551d box.
I was able to connect and read the full flash. I didnt try out more yet.
But i was confused, directly after reading out the flash and disconnecting and shutting down thenefmoto flasher, I tryed to read fault codes etc with vag com, it showed me not the number of my ecu in the first field. It was sth. like "THi-SS I..." or so. Also fault codes have not been supported. Is that normal?
I was afraid that Ive messed up my ecu
.
After I turned off and on the ignition, everything was fine and as it should be.
Fault codes are shown (If there are) and everything elsa as it has to be. I started the car for a test, and it started as it should.
So everything seems to be fine.
