What is Service Action 90X4?

Service Action 90X4 involves the replacement of the gateway control module, also referred to as the INTERFACE (Gateway control module), in affected Audi vehicles. This is not a recall for an immediate safety defect but a customer satisfaction campaign to ensure optimal vehicle performance and prevent future problems. The repair will be performed at no cost to owners and is expected to take up to three hours to complete, though dealers may require additional time for preparation and scheduling.

Important Warnings for Owners

• Free of Charge Expiration: This service action will be available for you free of charge only until May 21, 2029. If you wish to have this service performed after that date, your dealer's normal costs associated with this repair will apply.
