This TSB applies to 2011-2012 Audi A6 and A7 models, VIN range 0000001-999999. After replacing the electromechanical steering with the control unit J500, the unit cannot be coded via SVM spec/actual.
All new replacement power steering control units (J500) must be coded and parameterized using online SVM spec/actual or an SVM code. If the SVM spec/actual returns a response of “Check Hardware,” then the SVM code is required to code and parameterize the new replacement control unit.
The SVM code can be found in Parts Bulletin 9-97. All parts bulletins are located on the ETKAinfo.com website. The link to ETKAinfo.com is indicated by an icon ?@.
Once the icon is selected, the ETKAinfo.com website will be automatically opened. Next, the user must select the tab labeled “Infoline,” than set the Make to “Audi” in the dropdown menu, then select the tab labeled “Technology,” and then select the left menu option labeled “GP bulletins.”
When replacing the power steering control unit (J500), online coding and parameterization must first be attempted using an SVM spec/actual comparison. If the SVM spec/actual returns a response of “Check Hardware,” 5then it is possible that one of the SVM codes (listed below) is required to code and parameterize the new replacement control unit. Tip: The SVM Exchange Code (XCHG44A001) may be required.
