hi everyone. im trying to retrofit hill hold in a 2011 s5, so i bought an 1at abs module. it came from a 2015 s5, donor vin WAUGGAFR0FA008959. PN is 8K0 907 379 CP (ESP8 quattro H09 0020)

however, it seems i managed to get the only module that has 4 bytes coding i could find... hence not a lot of help found and the usual tutorial wont apply. if someone can help me with it id appreciate. even if by telling me its a no go so i can chase another module.

this is the coding that came with it: 281D1A01. from what ive searched, byte 0 indicates the vehicle, so for a5 should be 2D, and s5 should be 29. source: https://forums.ross-tech.com/index.php?threads/27749/

anyway... cant make the errors go away, and cant make the autohold button work.

THANKS!
