Why does the AUDI warning system suddenly prompt?
3 Answers
When the message 'Audi pre-sense system malfunction, please contact service' appears on the instrument cluster, it indicates that the Audi pre-sense system cannot guarantee vehicle detection. For safety reasons, the system has been deactivated. Common causes for this warning include misaligned or damaged radar sensors. The vehicle should be taken to a repair facility as soon as possible for inspection to determine the cause of the malfunction. Here is more information about the Audi pre-sense system: 1. Principle of the Audi pre-sense system: The Audi pre-sense system can take measures to protect occupants and road users. Through the networking of different vehicle systems, the basic version of the pre-sense system can identify dangerous driving situations and take preventive occupant protection measures. 2. Function of the Audi pre-sense system: The front pre-sense system uses radar sensor and camera data from the adaptive cruise control system to calculate the likelihood of rear-end collisions. The rear pre-sense system includes all functions of the basic pre-sense system. It uses radar sensor data from the side assist system and calculates the possibility of being rear-ended by following vehicles under system-available conditions. The urban pre-sense system uses camera data to identify collision risks with vehicles and pedestrians under system-available conditions.
My Audi's pre-sense system suddenly alerted, possibly due to dirty sensors or false alarms. Audi's systems like this rely on radar and cameras to detect road obstacles, and if these components have dust, rain, or dirt on them, they can easily trigger false warnings. I remember last time when I was driving in the rain, it kept alerting frequently. After stopping and wiping the radar area under the front bumper with a wet cloth, the problem disappeared. Hardware issues like damaged sensors can also cause similar situations, especially more common in older cars. For safety, don't ignore it, as the system is designed to prevent accidents. It's recommended to first clean it simply. If the alerts persist, go to the 4S store for a professional check to avoid risks during long-distance driving.
The sudden activation of the warning system might be caused by a software bug or aging. Audi models have advanced warning features, but delayed updates can lead to errors. I experienced fewer alerts after one software update. Check the fuse box, as a blown fuse can cut off power to the system. Cleaning the camera is the first step, but avoid disassembling hardware yourself to prevent damage. Over time, decreased sensor sensitivity may also cause frequent false alarms, especially in congested urban areas. For safety, develop a habit of regular maintenance, such as wiping the sensor area during each car wash. Remember to stay calm and not let warnings distract you from driving.
