Dear all,
I have done the following (boundaries: Audi RS4 B5 F-ECU, immo off):

I tried to flash the ECU with new dataset (checksum correct) with the nefmoto flash tool. But unfortunately I could not flash completely - in between the flash process I've had an error message saying that some sectors could not be written.
Then I removed the flash, put in an adapter (socket - for quick exchange if the flash) and flashed it with the basic Dataset first. What now happens: I can start the car, it is running. Then if you turn off the key, then next time you can not start the engine again. If you now plug off the ECU and plug in, then you can start again. Then I checked the error codes. there is one error saying that the ecu coding is wrong. then turn off the engine- not able to start agein.

Does anybody have an Idea??? That would be great...

many thanks in advance

Greg
