Programming and Relearning

Coding the ESP control module adapts the control module to the vehicle.

New control modules from the parts distribution center are un-coded and must be coded after being installed.

Coding is only possible if a dealership number stored in the VAG1551 scan tool.

Before the control module can be coded, "Login Procedure" function 11 must have been successfully carried out using the VAG1551/1552 scan tool.

After the control module is coded, the steering angle sensor -G85- must be zeroed without leaving "Basic Setting" function 04, display group 001.

Note: If the control module is coded with code 00000 or with a code that does not match the vehicle, the ABS warning light K47- and the traction control indicator light -K86- light continuously, and the DTC 01044 - "Control module incorrectly coded" is stored in the DTC memory of the control module.
