2019-2023 Audi Pre Sense Malfunction TSB 2062974/3

Audi has released Technical Service Bulletin (TSB) 2062974/3 to address customer concerns regarding a "Pre sense malfunction" message appearing in the Driver Information System (DIS). This bulletin applies to various 2019-2023 Audi models, including the A6, A7, A8, Q7, Q8, and their performance variants.

The TSB clarifies that this message, often associated with specific diagnostic trouble codes, does not indicate a functional fault requiring repair. Instead, it is a condition that can arise under certain circumstances related to the vehicle's safety belt tensioning system. Owners experiencing an Audi pre sense malfunction should be aware of the information provided in this communication.

Symptoms

Owners of affected Audi vehicles may observe the following:

• The message "Pre sense malfunction" is displayed in the driver information system (DIS) immediately after starting to drive.
• Functions of the driver assistance systems may be sporadically disrupted.

Despite these indicators, the TSB notes that the function of the seat belts themselves is not affected by this condition.

Fault Codes / DTCs

When this condition occurs, the following diagnostic trouble codes (DTCs) may be stored as passive/sporadic entries in the airbag control module, identified as J234 (address word 0015):

Code	Description	Module
B130474	Left front belt tensioner control module, actuator deviates	airbag control module J234
B130574	Right front belt tensioner control module, actuator deviates	airbag control module J234

These codes specifically point to deviations in the left and right front belt tensioner control modules.

Technical Background

Modern Audi vehicles are equipped with safety belts that feature reversible belt tensioners. These tensioners are designed to tighten the seat belt at the start of driving or in specific driving conditions to ensure the belt rests closer to the occupant's body. This action enhances safety by reducing slack.

The "Pre sense malfunction" message, and the associated DTCs B130474 and B130574, can appear if the customer repeatedly loosens the seat belt while the tensioner is attempting to tighten it. If this occurs for approximately five seconds, the system may trigger the warning message and store the diagnostic codes in the airbag control module.

Important Warnings for Owners

Audi Technical Service Bulletin 2062974/3 contains critical information for owners and technicians:

• "Do not perform any repairs. Any repairs for this concern may be denied."
• "The DTC(s) can be ignored and will be deleted automatically when exiting GFF in ODIS Service."
• "Tip: Parts replacement does not solve this issue. Claims for replaced parts will be subject to review."

These warnings emphasize that the presence of DTCs B130474 and B130574 for an Audi pre sense malfunction does not indicate a component failure. Attempting to replace parts or perform other repairs will not resolve the issue and may result in denied warranty claims.

What Owners Should Do

If you experience the "Pre sense malfunction" message or your vehicle has stored DTCs B130474 or B130574, it is important to understand that, according to TSB 2062974/3, no repair action is required. The diagnostic trouble codes are considered sporadic and will clear automatically during the normal diagnostic process in ODIS Service.

There is no need to visit a dealership specifically for this issue, as no parts replacement or service procedure is recommended. This TSB supersedes previous bulletin Group 69 number 21-67 dated August 5, 2021, and provides updated guidance for this condition.
