1. What does U13EB00 mean?

U13EB00 is an Audi DTC meaning “Emergency call module and communication unit Flight mode activated.” Verified Audi bulletins associate it with the emergency-call/communications module at address 0075.

2. Technical explanation

Audi identifies the module as the Emergency Call Module and Communication Unit, also called the ConBox/Connectivity Box. Audi documentation states that, beginning with MY2019, connectivity functions including Key User Pairing, Remote Services, SOS, and Roadside features moved to this module. The verified evidence does not establish a root cause for every occurrence of U13EB00.

3. What system is affected?

Emergency Call Module and Communication Unit (ConBox/Connectivity Box), diagnostic address 0075. Audi documentation references module identifiers J949 and J989 in the supplied bulletins.

4. How serious is this code?

Unknown. Verified evidence does not assign a severity level.

5. Symptoms you may notice

  • A red e-call LED may be present.
  • An “SOS Malfunction” message may appear in the instrument cluster.
  • In some documented cases, flight mode had been successfully removed during PDI but was found active again.
  • In other documented cases, an MMI message concerning emergency-call-service subscription expiration was present together with U13EB00 and P169A00.

6. Possible causes

  • Audi stated in a 2023 bulletin that the complaint was under analysis and that the supplier required parts with the fault active to determine the root cause and develop a solution.
  • Not yet established by verified evidence.

7. Can I still drive the vehicle?

Unknown. The supplied verified evidence does not determine whether the vehicle is safe to drive with U13EB00.

8. Can I charge the vehicle?

Unknown. The supplied verified evidence does not determine whether the vehicle is safe to charge with U13EB00.

9. What you can safely do

  • Arrange diagnosis by an Audi dealer or qualified service facility, particularly if the red e-call LED or SOS Malfunction message is displayed.
  • Provide the stored DTC U13EB00 and any instrument-cluster or MMI messages to the service facility.
  • Do not attempt high-voltage or telematics-module repair procedures yourself.

10. Step-by-step troubleshooting

  1. Have the Emergency Call Module and Communication Unit scanned at address 0075 for U13EB00.
  2. For the specified ConBox, Audi states diagnosis requires a VAS 6154 wireless diagnostic head.
  3. Check for accompanying documented DTCs, including P169A00 in the engine control module, when applicable.
  4. Use the applicable Audi technical service information based on exact model year, model, and vehicle configuration.

11. When to contact service

Contact an Audi dealer or qualified Audi service facility. The supplied evidence documents manufacturer diagnostic procedures and an issue under analysis; it does not provide a universal owner-performed fix.

12. What the service center may check

  • Confirm U13EB00 in the emergency-call/communications module at address 0075.
  • Document whether the e-call LED is red and whether “SOS Malfunction” appears.
  • Determine whether flight mode was previously removed during PDI, where applicable.
  • Check for P169A00, “Transport mode active,” in engine control module address 0001 when relevant.
  • For MY2023 ConBox flight-mode reset concerns, refer to Audi TSB 2069329 as identified by the supplied NHTSA manufacturer communication.

13. Possible repair or resolution
