2021-2024 Audi Suspension Control Module Malfunction TSB

Audi has released Technical Service Bulletin (TSB) 2051336/7 to address a specific suspension control module malfunction that can affect various 2021-2024 Audi A4, A4 allroad, A5, RS 5, S4, and S5 models. This TSB, issued on May 19, 2023, supersedes an earlier bulletin, Group 43 number 22-63 dated June 9, 2022, indicating a revision to the guidance provided to technicians.

The core of the issue involves a specific diagnostic trouble code (DTC) related to the vehicle's suspension system. Owners might notice a warning light on their dashboard, signaling a potential problem with the damper control system. This TSB provides a clear, concise solution for the Audi B200FF0 suspension malfunction.

Symptoms of Suspension Control Module Malfunction

Owners experiencing this issue will typically observe a specific warning on their instrument cluster. The primary symptom is: "The warning lamp for the damper control in the instrument cluster is on."

This warning indicates that the vehicle's damper control system, which manages ride comfort and handling, has detected an anomaly. While the TSB notes that this DTC does not affect the vehicle's handling characteristics, addressing the warning is important for maintaining optimal system function and peace of mind.

Fault Codes (DTCs)

When diagnosing the reported symptom, technicians may find a specific diagnostic trouble code (DTC) stored in the vehicle's control modules. The relevant DTC for this Audi B200FF0 suspension malfunction is:

• DTC B200FF0 (internal malfunction)

This code can be stored in either the drivetrain control module, identified as J775 (address word 0074), or the electronic damping control module, J250 (address word 0014). The presence of this specific code, B200FF0, is key to identifying the issue covered by TSB 2051336/7.

Important Warnings for Owners

Audi has provided crucial guidance within TSB 2051336/7 that directly impacts how this issue should be addressed, and what owners should know:

• Do not replace parts: The TSB explicitly states: "Parts replacement does not solve this issue. Claims for replaced parts will be subject to review." This means that attempting to replace components like the suspension control module or related parts will not resolve the underlying problem and could lead to unnecessary costs. It's vital for owners to be aware of this to avoid being upsold on unneeded repairs.
• Basic settings are key: Technicians are instructed to "Perform any additional basic setting requested by the GFF (according to the equipment installed in the vehicle)." This highlights that a software-based adjustment, rather than a hardware replacement, is the correct path to resolution.

Diagnosis and Repair Procedure

The repair for the Audi B200FF0 suspension malfunction is straightforward, focusing on software and system calibration rather than hardware replacement. According to TSB 2051336/7, the procedure involves two main steps:

1. Delete the DTC: The first step is to clear the stored DTC B200FF0 from the relevant control module (J775 or J250).
2. Perform suspension basic settings: After clearing the code, technicians must perform a suspension basic settings procedure. This recalibrates the system, ensuring all components are operating within their specified parameters. This process is crucial for resolving the internal malfunction indicated by the B200FF0 code.

Technicians are also advised to perform a Guided Fault Finding (GFF) scan to ensure no other DTCs are present in the control module after the repair. This ensures a comprehensive resolution to any related issues.
