This TSB applies only to the A4 allroad. This information does not apply to A4/S4 sedans & A5/S5/RS 5 coupe
vehicles. Please reference TSB 2030583 for A4/S4 sedans & A5/S5/RS 5 coupe vehicles.
1. Use the Control Module ODB function within ODIS to determine the hardware version, the production date,
and the software part number of both the lane change assistance control module, J769, and the lane change
assistance control module 2, J770:
Using ODIS:
• Start Diagnosis -> Fill out Engine Information from
drop down menu -> Uncheck option for “Guided
Fault Finding” --> Select Tab “Control module list” -> Scroll down list to “3C Lane Change Assistant”
(ECU option will be greyed out) -> Right click on
“3C Lane Change Assistant” and select “Identify
control module” (Figure 1).
Wait for the information to populate. This usually takes
5-10 seconds.

Figure 1. 3C Lane Change Assistant is greyed out
until “Identify control module” is selected.
• Once the information has populated, right-click on
“3C Lane Change Assistant” and select “Control
Module ODB” (Figure 2).
Wait for the Control module OBD Results tab to
populate the ECU information.

Figure 2. Control module OBD option is available
after “Identify control module” completes.
