1.Camshaft sensors are the same on all BBK B6\B7 engines, I checked this.
2. Immediately when you turn on the ignition (without starting the engine), an error appears (open or short to + of the camshaft sensors).
3.Synchronization is ok.
4. I wrote down my firmware 8e0910560N, removed the connectors from the camshaft sensors and got the same errors as with firmware 8e0910560J
In this case you can:
a) Compare the two firmwares and check what the difference is.
b) Compare the wiring diagrams for both cars (EU4 and EU2).
Again - there is nothing wrong with the 8E0910560J file here like you say, and your own file has HW 4E0907560 inside. Look at 0x18000.
This is also why a user here had no problems to flash BBK file to A8 4E ECU. Many of the BBK cars are using A8 4E ECU HW from factory, only the SW is different.
