Audi B11E101
DTC B11E201 (Video line 2 for night vision system). Technical Background Tolerances in the instrument cluster can cause it to erroneously detect a wiring problem. Production Solu
Quick answer
For certain 2019–2020 US Audi A8 and e-tron vehicles, DTC B11E101 relates to the night vision system video line. Audi states that instrument-cluster tolerances can incorrectly detect a wiring fault when the relevant wiring has been checked and found good.

1. What does B11E101 mean?
For certain 2019–2020 US Audi A8 and e-tron vehicles, DTC B11E101 relates to the night vision system video line. Audi states that instrument-cluster tolerances can incorrectly detect a wiring fault when the relevant wiring has been checked and found good.
2. Technical explanation
Audi’s official service information identifies B11E101 as “Video line for night vision system.” The related condition may be stored sporadically in the instrument cluster control module J285 (address 0017) and/or alongside B11E201 in the night vision system control module J853 (address 0084). Audi attributes the false wiring-fault detection to tolerances in the instrument cluster.
3. What system is affected?
Night vision system and instrument cluster control module.
4. How serious is this code?
Not yet established by verified evidence.
5. Symptoms you may notice
- B11E101 may be stored sporadically in the instrument cluster control module J285.
- Audi documentation describes an erroneous detection of a wiring problem after the wiring between the night vision system and instrument cluster has been checked and found to be in good condition.
6. Possible causes
- Instrument-cluster tolerances can cause erroneous detection of a wiring problem.
- An actual wiring fault is not established by the supplied evidence; Audi’s bulletin applies when the wiring between the night vision system and instrument cluster has been checked and found to be in good condition.
7. Can I still drive the vehicle?
Not yet established by verified evidence.
8. Can I charge the vehicle?
Not yet established by verified evidence.
9. What you can safely do
- Arrange diagnosis by an Audi-qualified service facility using the applicable Audi diagnostic process.
- Do not assume that B11E101 alone confirms damaged wiring; Audi documents a condition in which the wiring is good and the detection is erroneous.
10. Step-by-step troubleshooting
- Audi specifies use of an ODIS tester and an SVM code in the related service procedure.
- The supplied evidence states that the wiring between the night vision system and instrument cluster should be checked and found to be in good condition before applying the bulletin context.
- No further user-performed diagnostic procedure is established by the supplied evidence.
11. When to contact service
Contact an Audi service facility if B11E101 is present, particularly if it returns sporadically. The applicable Audi communications specify ODIS and an SVM code.
12. What the service center may check
- Scan the instrument cluster control module J285 (address 0017) and, where applicable, the night vision system control module J853 (address 0084).
- Check the wiring between the night vision system and instrument cluster as described by Audi.
- Use ODIS and the applicable SVM code referenced in Audi service information.
13. Possible repair or resolution
- Audi’s verified bulletin evidence identifies an instrument-cluster tolerance condition that can falsely detect a wiring problem.
- The specific completed repair or programming outcome is not established by the supplied evidence excerpt.
- Audi lists no production solution as applicable in the supplied evidence.
