2021-2026 Audi Control Functions Restricted TSB 2076287/1

Audi has issued Technical Service Bulletin (TSB) 87 24 93 2076287/1 to address a common concern among owners of 2021-2026 Audi vehicles: restricted control functions within the vehicle interior. This bulletin provides crucial information regarding the cause of this issue and its implications for warranty coverage. Owners experiencing a 2021 Audi e-tron control functions restricted issue should review this information carefully.

Symptoms of Restricted Interior Controls

Owners report that no settings can be changed using the controls in the vehicle interior. This widespread problem can affect various critical systems and components, making it difficult or impossible to adjust vehicle settings. The specific areas where owners may notice this restriction include:

• The air conditioning console in the front of the vehicle.
• The air conditioning console in the rear of the vehicle.
• Switches located in the center console.
• Switches found in the dash panel.
• Multifunction buttons on the steering wheel.
• Light switches.
• The roof module.
• The rear lid release button.
• The mirror adjustment buttons.

If you are experiencing any of these issues, it indicates a potential problem with your Audi's interior electronics.

Root Cause: Moisture Damage to Electronics

The underlying cause of these restricted control functions is often moisture damage to the printed circuit boards (PCBs) inside the affected components. The TSB includes figures illustrating evidence of moisture on these PCBs, leading to malfunctions. This moisture ingress can disrupt the sensitive electronic pathways, preventing the controls from responding correctly.

Critical Warning: Warranty May Be Voided by Cleaning Agents

Audi has identified a significant factor contributing to this moisture damage: the excessive use of cleaning agents and disinfectants. The electronic components, particularly in the front and rear air conditioning controls, are highly susceptible to these substances. Owners should be aware of the following critical information:

• Warranty Rejection: If defective air conditioning controls or any type of switch or touch panel show residue of cleaning agents or disinfectants in the component, the warranty claim will be rejected.
• External Influence: This type of damage is considered due to outside influence and is explicitly not covered by any Audi Warranty.

This means that if your Audi's interior controls fail due to exposure to cleaning products, you will likely be responsible for the repair costs. The TSB specifically mentions professional equipment like the Tornador ® cleaner, advising that expertise from cleaning companies should be sought when such equipment is used, to avoid damage.

Recommendations for Cleaning and Repair

To prevent the 2021 Audi e-tron control functions restricted issue and potential warranty invalidation, Audi recommends exercising caution when cleaning your vehicle's interior. Avoid excessive application of cleaning agents and disinfectants, especially near electronic control surfaces and switches. If you use professional cleaning services or equipment, ensure they are aware of the sensitivity of modern vehicle electronics.

If your vehicle is already experiencing restricted control functions, and you suspect cleaning agents may be the cause, be prepared for the possibility that repairs may not be covered under your Audi warranty, as outlined in TSB 87 24 93 2076287/1.
