2021 Audi MMI Map Update Error TSB 2073866/1

Owners of certain 2021 Audi vehicles equipped with the MIB2+ infotainment system may encounter issues when attempting to install online map updates. This problem, identified in Technical Service Bulletin (TSB) 2073866/1, prevents the successful installation of new map data, leading to various error messages displayed on the MMI screen. This can be a frustrating Audi e-tron MMI error that impacts navigation functionality.

Symptoms

When an automatic online map update fails to install successfully, 2021 Audi owners may observe one of the following error messages on their MMI display, either immediately or after a period of time:

• "The update data is not compatible."
• "Error: the update is not possible."
• "An unknown error has occurred. The operation has been cancelled."
• "Please wait ..."
• Or other similar error messages.

Technical Background

The root cause of this map update failure is often corrupt map data residing within the control unit for information electronics, identified as J794. This corruption typically stems from a previous online map update that did not complete correctly.

Important Warnings

Audi has issued specific warnings regarding this service procedure:

• Warranty Coverage: "Map updates outside the scope of the license on the vehicle are not covered under the TSB. Always use a map version that is compatible with the license on the current vehicle."
• Claim Denial: "Claims for map activation documents may be denied by warranty."

Owners should ensure their map updates are within the vehicle's license scope to avoid potential warranty issues.
