This indicates that during routine service or after certain repairs, the system may fail to calibrate correctly. The underlying cause is related to the vehicle's electrical system software, which governs the operation and calibration of these critical components.

Repair Procedure Summary

The resolution for this issue involves a software update. Audi dealerships will apply a new software version to the vehicle's electrical system. This update is designed to correct the conditions that lead to the unsuccessful Audi e-tron laser scanner alignment, ensuring proper calibration and functionality of the laser scanner.

Owner Action

If you own a 2021 Audi e-tron, Q8, A6, or A7 and suspect your vehicle might be experiencing issues related to laser scanner alignment or ADAS functionality, it is recommended to contact your authorized Audi dealership. They can check if your vehicle is covered by TSB 10185265 and perform the necessary software update. Typically, TSB-related software updates are performed free of charge under warranty.
