Audi has issued Technical Service Bulletin (TSB) 90 24 21 2068380/5 to address an Audi instrument cluster fault B200049 that can result in a black screen or warning messages in the virtual cockpit. This TSB, dated August 29, 2024, is Revision 5 of the bulletin and supersedes TSB Group 90 number 24-01 dated June 5, 2024, for reasons including updated customer statements, warranty information, and service procedures.

Symptoms

Owners of affected Audi vehicles may experience one of two primary symptoms related to the instrument cluster:

• The instrument cluster display shows the message: “Instrument cluster: fault. Limited warning messages. Please contact workshop”.
• The Audi Virtual cockpit remains black when the vehicle is started.

Fault Codes / DTCs

When these symptoms occur, technicians will typically find the following Diagnostic Trouble Code (DTC) stored in the Instrument Cluster control module -J285- (diagnostic address 0017):

• DTC B200049: Control module faulty static/active, with symptom code 10485833.

This DTC indicates a fault within the instrument cluster's control module itself, pointing to a hardware problem.

Diagnosis and Trigger Conditions

The root cause of the Audi instrument cluster fault B200049 is a hardware issue within the Audi virtual cockpit, stemming from a discrepancy in the production process. Optimized instrument cluster hardware has been produced as of August 1, 2024.
