Affected Vehicles



Condition



After replacing the Comfort System control unit (J393), the control unit cannot be coded via SVM spec/actual.



Technical Background



All new replacement Comfort System control units (J393) 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 9-90. All parts bulletins are located on the ETKAinfo.com website. The link to ETKAinfo.com is



indicated by the icon seen in Figure 1.



Production Solution



Not applicable.



Service



When replacing the Comfort System control unit (J393), 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", then it is possible one of the SVM codes listed below is required to



code and parameterize the new replacement control unit.



Tip: No main software update is performed during this SVM communication.

^If the vehicle is a 2008/2009 model year A5/S5 with an original control unit part number of 8K0907289*, you are NO longer required to run the



8T46U002 and 8T46U003 SVM codes. The actions previously provided by these SVM codes have been incorporated into the SVM code



XCHG46A001.
