Technical Service Bulletin

Figure 3: e-Call LED illuminated green.

If the e-Call LED is not illuminated, or illuminated red, and no other DTCs then listed in this TSB, or only
“ghost faults” (marked as unauthorized in the GFF log) are present, it is likely that the issue is due to a
connectivity or backend issue, not a hardware issue. In these cases, this TSB does not apply.Please do
not replace parts solely because of ghost faults.
The complaint may or may not be reproducible.
The vehicle often recovers full functionality temporarily when the control module for emergency call module and
communication unit (ConBox) -J949- (address word 0075) is accessed via ODIS, or after a vehicle bus sleep
cycle.

Technical Service Bulletin
A software issue related to the ConBox may temporarily cause Bluetooth and Connectivity functions to be
temporarily not available.

Production Solution
New ConBox software will be implemented in production in MY2024.

Service
1. Explain to the customer that a solution is expected to be available by the end of the 2nd quarter of 2024
(subject to change) and that no repairs are necessary at this point. Do not replace any components for this
condition since this will not resolve the customer’s concern.
2. Create a PSS record in the PSS application through the Pending Service Solutions (PSS) link in AccessAudi
(under Related Links >> Service).
3. Our current observations suggest that functionality is usually recovered temporarily:
a. By accessing the ConBox via the ODIS diagnostic tool.
b. if the vehicle is driven outside of the coverage of the current mobile network cell and it registers to a new
mobile network cell.

Warranty
This TSB is informational only and not applicable to any Audi Warranty.
