Coding

The latest versions of VCDS come with a Coding Helper (availability may vary) allowing the user to determine the Coding based on Vehicle Equipment using the PR-Codes . In case you are unable to determine the Coding, please contact us directly and we can try to assist registered customers with the Coding Process. Every inquiry on this topic has to include a full Auto-Scan as well as which parts have been replaced and why, also make sure the Auto-Scan includes the complete VIN of the vehicle in question. The Factory Tool will normally perform the Coding by querying Software Version Management (SVM) for the proper Value.

Basic Setting

  • When having the steering wheel straight again stop the vehicle with the wheels pointed straight.
  • Ensure that the steering wheel is not moved again.
  • Keep the engine running and do not switch off the ignition.
  • System voltage at least 12.0 V.

Replacement

After Replacing this Control Module these Steps have to be performed in the following Order:

In case you are having trouble with procedure please contact us directly and we will assist you with the Coding Process. Every inquiry on this topic has to include a full Auto-Scan as well as which parts have been replaced and why, also make sure the Auto-Scan includes the complete VIN of the vehicle in question.
