Audi B200049
a. In ODIS, go to Self-diagnosis >> Address: 0017 System name: 0017 >> Instrument
Quick answer
For certain US-market Audi models, DTC B200049 may be stored in the instrument cluster (J285, address 0017) when the Audi virtual cockpit display is blank intermittently or constantly. Audi’s cited service communication attributes this case to a hardware defect in the virtual cockpit and directs technicians to check its production date in ODIS.

1. What does B200049 mean?
For certain US-market Audi models, DTC B200049 may be stored in the instrument cluster (J285, address 0017) when the Audi virtual cockpit display is blank intermittently or constantly. Audi’s cited service communication attributes this case to a hardware defect in the virtual cockpit and directs technicians to check its production date in ODIS.
2. Technical explanation
B200049 is documented in supplied Audi/NHTSA evidence in more than one control-module context. For instrument cluster J285 (address 0017), it is identified as “Control Module Faulty” in a communication concerning blank Audi virtual cockpit displays. That communication states that an optimized virtual-cockpit hardware design was implemented in production. Separately, another Audi communication documents B200049 with symptom code 7353984 in the power-steering control unit J500 (address 0044), where the stated technical background is a software issue. Therefore, the DTC alone does not establish a single fault location or repair; the control-module address is essential.
3. What system is affected?
Verified evidence identifies two possible contexts: the instrument cluster/Audi virtual cockpit, J285, address 0017; and the power-steering control unit, J500, address 0044. The supplied diagnostic title specifically references ODIS navigation to address 0017 Instrument.
4. How serious is this code?
Not yet established by verified evidence. The supplied instrument-cluster communication describes a blank display, while the separate power-steering communication describes a red steering warning lamp and reduced steering assist.
5. Symptoms you may notice
- For J285/address 0017: the Audi virtual cockpit may be blank intermittently or constantly.
- For J500/address 0044: a red steering warning lamp may illuminate and steering assist may be reduced.
6. Possible causes
- For J285/address 0017, Audi’s cited communication states there is a hardware defect in the Audi virtual cockpit.
- For J500/address 0044 with symptom code 7353984, Audi’s cited communication states a software issue was identified.
- Which of these applies cannot be determined from B200049 alone; the module address and vehicle-specific diagnostic results are required.
7. Can I still drive the vehicle?
Not yet established by verified evidence. If the red steering warning lamp is illuminated or steering assist is reduced, the supplied evidence does not provide a driving determination.
8. Can I charge the vehicle?
Not yet established by verified evidence.
9. What you can safely do
- Record whether B200049 is stored in J285/address 0017 or J500/address 0044.
- Note whether the virtual cockpit is blank, or whether a red steering warning and reduced steering assist are present.
- Arrange diagnosis by an Audi service facility using ODIS.
10. Step-by-step troubleshooting
- For the virtual-cockpit case, the cited Audi communication directs technicians in ODIS to Self-diagnosis, address 0017, Instrument, then to check the production date of the Audi virtual cockpit.
- For the power-steering case, the cited Audi communication directs service to follow TSB 2011732:00 Software Version Management operating instructions and update the control unit through SVM.
- Further troubleshooting steps are not established by the supplied verified evidence.
11. When to contact service
Audi service is appropriate for vehicle-specific ODIS diagnosis, confirmation of the module storing the DTC, and application of any applicable Audi service communication.
12. What the service center may check
- Confirm the storing module and address: J285/address 0017 versus J500/address 0044.
- For J285/address 0017, check the production date of the Audi virtual cockpit as directed in the cited communication.
- For J500/address 0044 with symptom code 7353984, assess eligibility for the documented SVM software update process.
13. Possible repair or resolution
- For the J285 virtual-cockpit case, the cited communication states that optimized hardware was implemented in production; the exact vehicle repair action is not fully established by the supplied excerpt.
- For the J500 power-steering case with symptom code 7353984, the cited communication documents an SVM update process and states the software issue was corrected in production.
- No universal repair resolution for B200049 is established because the same DTC is documented in different modules and fault contexts.
