Kess, FG54...

kess clone is possible? checksum is correct?

Yes, but in some cases the coding of the ECU changes, so first you must check it with VCDS and save it, and code after flashing.
With FG no such problem.
Some of ECUs didn't allow OBD read/write...

yes, coding is different after flashing. I read/write with kess v2 no problem. Bobolin4o have you got solution for egr off?
