Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Code Control Module (function 07): Notes
Vehicles manufactured from January 1999 onward must be equipped with ABS control module (w/EDL) -J104-, Part No. 8D0 907 389 A/D/E. These control units are codable. New control modules supplied as replacement parts are uncoded and must be coded after installation.
Control modules with Part No. 4B0 907 389 cannot be coded.
The coding of the ESP control module serves to adapt the control module to the vehicle.
Coding is only possible after the workshop code (WSC) has been entered into VAG 1551 scan tool.
