2021-2022 Audi Driver Assist Systems Malfunction TSB B200FF9

Symptoms

Owners of affected Audi vehicles may experience their driver assistance systems sporadically not working. This can lead to various warning messages displayed in the instrument cluster, indicating a temporary loss of functionality for key safety features.

Common messages include:

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

Typically, these systems become available again after an ignition cycle or when the vehicle enters bus sleep. If you encounter the Audi driver assist B200FF9 fault, these are the primary indicators.

Fault Codes / DTCs

When the driver assistance systems malfunction, a specific Diagnostic Trouble Code (DTC) is stored in the vehicle's control modules. This code helps technicians identify the root cause of the issue.

This DTC B200FF9 indicates an internal malfunction within the J1121 driver assistance systems control module.

Diagnosis / Trigger Conditions

The underlying cause of the Audi driver assist B200FF9 fault is that the driver assist control module's diagnostic checks are too sensitive. This sensitivity leads to false positive detections of malfunctions, causing the systems to temporarily shut down and log the DTC.

What to do if your vehicle is affected

Audi has identified that a solution for this condition is forthcoming and is expected in the fourth quarter of 2021. At present, no component replacements are necessary, as replacing parts will not resolve the underlying issue of overly sensitive diagnostics.

If your vehicle exhibits these symptoms, Audi recommends creating a PSS (Pending Service Solutions) record. This record helps track the issue and ensures that your vehicle is noted for the upcoming solution. Your dealer can assist with this process.

Warranty coverage for this issue typically extends up to 48 months or 50,000 miles. For Audi Certified Pre-Owned (CPO) vehicles, specific warranty conditions (G10) apply. If your vehicle is outside of warranty, this Technical Service Bulletin serves as informational guidance.
