Important Warnings Regarding Chip Tuning

Audi emphasizes crucial information for owners whose vehicles may have been modified with chip tuning. It is vital for owners to be aware of the following:

• Ineffectiveness of Chip Tuning: Updating the engine control unit software will render any existing chip tuning ineffective.
• Potential Damage: In certain circumstances, the software update may even damage an engine control unit that has been chip-tuned.
• Warranty Exclusions: Damage to the engine control unit resulting from prior chip tuning cannot be billed to AUDI AG under warranty. Owners are advised to consult their Warranty and Maintenance booklet for details on how chip tuning impacts warranty coverage.
• Manufacturer Responsibility: Neither AUDI AG nor the dealership can be held responsible for any damage caused by the software update or for damage that occurs as a result of not having the update performed.

Customers with chip-tuned vehicles should clarify with their tuning company whether a software update is possible before proceeding. This information must be documented on the repair order and signed by the customer.
