Symptoms
Owners of affected vehicles may notice issues related to their vehicle's advanced driver-assistance systems (ADAS).

The TSB specifically highlights scenarios where the laser scanner alignment procedure is unsuccessful. 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.
