1. What does Adaptive driving assist: limited availability, see owner mean?
For applicable 2019–2021 US Audi A8 and e-tron vehicles, this alert can appear when dirt restricts the laser scanner’s detection capability. Certain driver-assistance features might then be unavailable.
2. Technical explanation
Audi’s official communication explains that the laser scanner has a cleaning function. If it is very dirty, such as after driving on dirt roads or through slush, it may be unable to clean itself. After three cleaning attempts, the function enters a 45-minute timeout that is reset by an ignition cycle. If contamination restricts laser-scanner detection, the instrument cluster displays: “Adaptive driving assist: limited availability, see owner’s manual.”
3. What system is affected?
Adaptive driving assistance / laser scanner cleaning and detection capability.
4. How serious is this code?
The diagnostic record lists severity as unknown. Verified evidence establishes that certain driver-assistance features might not be available while the message is displayed.
5. Symptoms you may notice
- Instrument-cluster message: “Adaptive driving assist: limited availability, see owner’s manual.”
- Certain driver-assistance features might not be available.
- Potential concern about increased washer-fluid consumption.
6. Possible causes
- Dirt restricting the laser scanner’s detection capabilities.
- A very dirty laser scanner that cannot clean itself, including contamination associated with dirt-road driving or slush.
