2022-2024 Audi Parking Aid Malfunction TSB 2069694/1

Audi has issued Technical Service Bulletin (TSB) 2069694/1 (also referred to as 91 23 80 2069694/1) to address instances where the parking aid system displays a "Front/rear parking aid: Sensor view restricted because of environmental factors" warning message. This TSB applies to 2022-2024 Audi A3, S3, RS 3, Q4 e-tron, and Q4 Sportback e-tron models. This Audi parking aid malfunction is often accompanied by specific diagnostic trouble codes (DTCs) related to environmental influences on the parking aid sensors.

This bulletin clarifies that the warning message and the associated DTCs, B107BF0 and B10FCF0, are typically triggered by external factors affecting the vehicle's ultrasound parking aid sensors. Understanding this TSB can help owners and technicians properly diagnose and address the root cause of the Audi parking aid malfunction without unnecessary part replacements.

Symptoms

Owners of affected Audi vehicles may observe the following in their instrument cluster:

• The warning message: "Front/rear parking aid: Sensor view restricted because of environmental factors"

This message indicates that the parking aid system's sensors are temporarily unable to function correctly due to external conditions.

Fault Codes / DTCs

When the Audi parking aid malfunction occurs, one or both of the following diagnostic trouble codes (DTCs) may be stored in the parking aid control module (-J446-, address word DA0076):

Code	Description
B107BF0	Rear parking aid sender, malfunction because of environment influences
B10FCF0	Front parking aid sender, malfunction because of environment influences

These DTCs are often accompanied by specific symptom codes, including 1080304 or 13959168 for B107BF0, and 1113328 or 13959169 for B10FCF0. These codes point directly to environmental factors as the cause of the sensor's temporary unavailability.

Important Warnings

Audi explicitly states critical information regarding the diagnosis and repair of this Audi parking aid malfunction:

• "Note: In this case, replacement of the driver assistance systems -J446- (DA0076) without clear findings is not effective. Part replacement of the -J446- (DA0076) does not solve this issue. Claims for replaced parts will be subject to review." This means technicians should not replace the parking aid control module if the issue is sporadic and caused by environmental factors, as it will not resolve the problem and may lead to warranty claim rejections.

Diagnosis and Trigger Conditions

The new generation of ultrasound parking aid sensors in these Audi models are highly sensitive to external influences. These can include:

• Dirt, mud, or debris on the sensors.
• Ice or snow accumulation.
• External ultrasound signals or noises.

When the system detects such problems, it temporarily disables itself to prevent false warnings. The warning message is then displayed to the driver.

Diagnosis depends on whether the issue is sporadic or constant:

• Scenario 1 (Sporadic Occurrence): If the warning message appears intermittently, it is likely caused by environmental influences. In such cases, no further measures or part replacements are necessary, as the system is functioning as designed under adverse conditions.
• Scenario 2 (Reproducible or Static Occurrence): If the concern is consistently reproducible or the warning remains active, it may indicate a faulty ultrasound sensor, mounting, or related circuit. A significantly increased frequency counter within the fault code's standard ambient conditions can also suggest a genuine malfunction. In this scenario, standard diagnostic procedures should be followed to pinpoint the specific faulty component.

Repair Procedure Summary

For technicians, TSB 2069694/1 outlines a series of checks to perform on the respective ultrasound sensors, depending on the stored DTCs:

1. Visual Inspection: Check the sensors for any dirt, ice, foreign objects, stickers, or an improperly fitted license plate that might obstruct their view.
2. Physical Damage Check: Inspect the bumper, air intake grille, and underbody for any damage that suggests an impact during parking, which could affect sensor alignment or function. Also, look for mechanical damage like stone chips or scratches on the sensors themselves.
3. Fitment Check: Verify the proper fit of the sensors, bumpers, and surrounding trim components. Loose or misaligned parts can interfere with sensor operation.
4. Measured Value Analysis: Use diagnostic tools to check the "Parking aid sender settling time in the parking aid control module, J446 (address word DA0076)." Observe for a cyclic or dynamic change in measured values when an obstacle is approached, which helps confirm sensor functionality.

If these checks reveal a consistent fault (Scenario 2), further standard diagnosis is required. However, if the issue is sporadic and linked to environmental factors (Scenario 1), no repair is needed, and replacement of the J446 control unit is specifically advised against.

Owner Action

If you experience an Audi parking aid malfunction with the "Front/rear parking aid: Sensor view restricted because of environmental factors" message, especially if it occurs intermittently or during adverse weather conditions, it is likely due to environmental factors.

• Initial Check: First, visually inspect your vehicle's parking sensors, bumper, and grille for any obvious obstructions like dirt, ice, or debris. Cleaning these areas may resolve the issue.
• Dealer Visit: If the warning persists after cleaning, or if it appears consistently regardless of environmental conditions, it is advisable to contact your authorized Audi service center. Inform them about the specific warning message and any DTCs you may have observed. Reference Audi TSB 2069694/1 to ensure they are aware of the manufacturer's guidance on this issue.
