Supersedes Technical DIAGNOSIS AND REPAIR Group 69 number 12 - 23 dated February 13, 2012 for reasons listed below.
Affected Vehicles
166
Condition
After replacing the airbag control unit, the control unit cannot be coded via SVM spec/actual.
Technical Background
All current and future Audi models require an SVM code to code and/or parameterized the new replacement airbag control unit for service. The
SVM code is listed in ETKA in the "REMARKS" area for the affected part number (See Figure 1 and 2). The SVM code could also be listed within
a parts bulletin on the ETKAinfo.com website which would be indicated in the "REMARKS" area within EKTA. This information can only be seen
in EKTA when performing an FI Search (VIN specific search).
Production Solution
Not applicable.
Service
When replacing the airbag control unit (J234) in a TT, A3, R8 GT, R8 GT Spyder, A5 Cabriolet, or C6 A6 an SVM coding must be performed using
the provided SVM code.
When replacing the airbag control unit (J234) in a B8 A4/S4, A5/S5, Audi Q5, A7, or D4 A8, an SVM parameterization and coding must be
performed using the provided SVM code.
Tip:
Do not run an SVM Specified vs. Actual Comparison! If you have already run an SVM Spec/Actual and the SVM Code listed below fails, then you
will need to contact the Technical Assistance Center to get the vehicle's CARPORT Reference set correctly. Additionally, its important to note that
167
no software update is performed during this SVM communication.
1. Find the original and replacement software part numbers and software versions from the GFF log or through VSD.
2. Use these numbers as the lookup values in the table above. All part numbers and software versions must match the values in one single row. If
no match is found, please contact the Technical Assistance Center.
3. Once a match is found, use the SVM Action Code listed in the same row of the table.
4. Enter the SVM code.
For TT, A3, R8 GT, R8 GT Spyder, A5 Cabriolet, & C6 A6 Only:
^ Enter code using Audi Flashing >> SVM Code for problem related update. This can be accessed through the VAS Testers main menu.
For A4/S4, A5/S5, Audi Q5, C7 A6, A7, & D4 A8 Only:
^ Enter code using Guided Fault Finding >> Go To >> Function Component Selection >> Software Version Management >> SVM - Direct
Input SVM code for vehicle conversion. When SVM suggests a new coding of the airbag control unit, enter a "NO" response to skip this
step. SVM will then provide a suggestion to parameterize the control unit. Enter a "YES" response to allow the SVM parameterization.
Tip:
If a new parameterization is available for the control unit, it must be performed before the new coding is changed, otherwise the new
coding will not be accepted by the control unit.
5. If no parameterization is suggested (Only for A4/S4, A5/S5, Audi Q5, A7, or D4 A8), or if no coding is suggested (Only for TT, A3, R8 GT,
R8 GT Spyder, A5 Cabriolet, or C6 A6), then check the color code on the control units service part label. Compare this color code to the
168
suggestion given by EKTA using the FI search function. If they do not match then re-order the correct part listed in EKTA. If they match, then
contact the Technical Assistance Center.
6. After the parameterization is complete (Not applicable to the TT, A3, R8 GT, R8 GT Spyder, A5 Cabriolet, or C6 A6), the coding of the
control unit will be automatically carried out by SVM (no user input required). If you are prompted to change the coding, then enter a "YES"
response.
7. At the end of the SVM communication a screen will indicate all changes that were made during the SVM communication. Please verify the
changes and ensure the coding was performed.
8. Exit SVM and perform the component protection test plan to remove the remaining DTCs.
