2021-2022 Audi Driver Assist Malfunction TSB B200FF9

Symptoms

Owners of affected 2021-2022 Audi vehicles may experience their driver assistance systems sporadically becoming inoperative. This can be a concerning issue, as these systems contribute significantly to vehicle safety and convenience. When this occurs, one or more of the following messages may be displayed in the instrument cluster:

• "Audi adaptive light malfunction."
• "Audi pre sense system malfunction."
• "Adaptive vehicle assistance restricted."
• "Adaptive vehicle assistance Predictive regulation restricted."

Typically, after an ignition cycle or a period of bus sleep (when the vehicle's electrical systems power down), the driver assistance systems become available again.

Fault Codes / DTCs

When the sporadic malfunction occurs, the driver assistance systems control module, identified as J1121 (address word 00A5), will store a specific diagnostic trouble code (DTC).

Code	Description	Symptom Code
B200FF9	Internal malfunction	2117657

This DTC B200FF9, combined with symptom code 2117657, points to an internal issue within the control module itself, rather than an external sensor or wiring problem.

Technical Background

According to Audi, the root cause of the sporadic Audi driver assist B200FF9 issue is that the driver assistance control module's diagnostic checks are too sensitive. This means the module is flagging minor, non-critical events as malfunctions, leading to the temporary shutdown of the systems and the storage of the DTC B200FF9.

Important Warnings for Owners

Audi has provided specific instructions for this condition:

• Do not replace any components for this condition. Replacing parts will not resolve the customer's concern, as the issue stems from the control module's sensitive diagnostic programming, not a faulty hardware component.
• A solution is forthcoming. Audi anticipates a permanent solution to be available in the first quarter of 2022. Owners should be aware that a software update or similar fix is being developed.

Warranty Information

This Technical Service Bulletin outlines specific warranty claim types and codes for technicians:

• Claim Type: 110 (up to 48 Months/50,000 Miles) or G10 (for CPO Covered Vehicles – Verify Owner).
• If the vehicle is outside of warranty, this TSB is for informational purposes only.
• Service Number: 9093
• Damage Code: 0039
• Diagnostic Time: GFF, 0151 0000 (Time stated on the diagnostic protocol, maximum 15 TU).
• Road tests prior to and after service procedure are listed with "No allowance" (0 TU), indicating these are not billable for this specific TSB as no repair is performed yet.

Next Steps for Owners

If you own a 2021-2022 Audi and are experiencing the sporadic failure of your driver assistance systems, accompanied by messages like "Audi pre sense system malfunction" or "Adaptive vehicle assistance restricted," and suspect the Audi driver assist B200FF9 fault, you should contact your authorized Audi dealer. Explain the symptoms you are experiencing. The dealer will be instructed to create a Pending Service Solutions (PSS) record in the PSS application via AccessAudi (under Related Links >> Service) or through the Technical Assistance page in Elsa. This helps Audi track the prevalence of the issue and ensures you are on record for a future solution.
