Good day everyone,

First, I want to thank everyone on the forum for all the great information. I have found everything I needed flash and tune my car. I have run into a problem though. I have an ecu, 4D0907551K, that I have flashed with 8D0907551M 0261207143 360857. No issues with the flash or the modifications to the bin thanks to all of your posts. It is coded wrong though. ABS is expecting data from the ECU and it is not being sent. The coding is 06621. I need 06721 to turn on ABS data. I have tried to use VCDS to code it but it will not take. I tried to login via the two codes VCDS provides then code but no luck. Wont stick. Does anyone know how to make the ECU accept the coding.

Let me know if further ECU info is needed that I did not provide.

Thank in advance

*Update*

The problem is an M box ecu will not accept an A6, or 2 as the last digit, because the bin is designed for an S4. Changed the last digit to 1, A4, and the ECU accepted the coding. 06711.
