Audi is a famous car manufacturing company renowned for manufacturing high-performance standard cars. For customer safety, the company has developed advanced technologies in the last few years that help avoid and deal with tragedies. Pre-sense is one of the top safety features among these technologies.
This article will discuss the most common problems with Audi pre sense fault and explain what the warning light means. Before taking it to a repair shop or an expert, we’ll also discuss some things you can do to fix the Pre Sense light by yourself.
What is the Meaning of Audi Pre Sense Warning Light ?
People like the pre sense feature in Audi cars, especially in Audi A3, A4, and Audi B9. Similar to BMW’s famous Collision Warning System, it keeps you and your passengers safe with radar, sensors, and some brilliant software. One of the best things about Audis is that they have a Pre Sense technology that work to stop accidents. Some things are wrong with Pre Sense because it is still a new device. Sometimes, the system may turn on by itself, and some drivers say that warning lights connected to the system flash on and off without any particular pattern.
People who have been through this know how scary it is. Radar monitors and cameras on the car’s front, back, and sides help the system figure out where other cars and people on foot will go. If the computer on board thinks there is a good chance of a crash, it will turn on the different safety systems. These include systems that warn the driver, electronic stability control (ESC) to keep the car from spinning, and the ability to apply the brakes. Nowadays, you can’t get an Audi without a pre sense system.
Why is My Audi Pre Sense Not Working Due to Surroundings?
Your Audi pre sense technology might not be working right because of several outside factors:
- Problems with the Car’s Sensors: The front, back, and side sensors of the car may not work because of dirt, snow, ice, or other debris blocking their path. It’s important to clean and check these sensors regularly so they can work properly.
- Bad Weather Conditions: Heavy rain, thick fog, or ice are bad weather that could make it harder for the cameras to identify objects. In this case, the device might suddenly stop working or give the incorrect data.
- Disturbance from Other Cars: Pre sense devices may sometimes get incorrect or no information because of electromagnetic disturbance from other vehicles.
- System Calibration: The present system won’t work properly if it isn’t correctly calibrated or set up. This could happen if someone changed the car’s settings or added or removed parts of the system without resetting them.
- Electricity Problems: The pre sense system might not work right if the car’s electricity isn’t working right, like if the wiring is bad or the battery is dead. If you think something is wrong with your car’s electrical system, you must have a skilled mechanic check it out.
4 Common Causes of Audi Pre Sense Fault
The most important causes are these:
1. Dirty or Blocked Parking Sensors
- When pre sense fault signs appear, it’s often because the parking sensors are dirty or blocked
- When the parking sensors are covered in dirt or trash, they are less accurate at detecting objects nearby.
- When ice and snow build-up, especially in places where it snows a lot, it could be difficult for sensors to work properly.
- It’s important to regularly clean the parking sensors, especially when bad weather is coming.
- Inspecting and cleaning the window and parking sensors is suggested after getting the Pre Sense Fault alert.
2. Unclean Windscreen Cameras
- If there is dirt or buildup on the windscreen, it could affect the quality of the camera system.
- Problems with vision make it harder for the sensors to find objects, which could cause the failed message to appear.
3. Recalibration of Windshield Cameras
- After changing the glass on your Audi, you’ll need to restart the cameras.
- Adjusting the cameras focus might be needed if the windshield’s shape or angle changes, as this could affect what they can see.
- Any approved service shop or Audi dealer can do the tuning.
4. Sensing Problem
- In very rare cases, pre sense faults could be caused by broken or malfunctioning sensors.
- When sensors are damaged by hitting rocks or other objects on the road, data may not be able to get to the car’s computer system.
How to Fix and Reset Audi’s Pre Sense Issue
In case of car won’t start, here are some ways to fix the Audi Pre Sense Fault and make it work again:
1. Clean Your Radar and Park Sensors
Ensure the radar and park devices are clean before doing anything else. Ensure they are clean and free of anything that could get in the way before using them.
2. Check the Windscreen Rain Sensors
Make sure the rain sensors on the windshield are clean and undamaged. If you want them to work well, make sure to clean them.
3. Calibrate the Camera if the Windshield was Recently Changed
You must adjust the camera’s focus if you just replaced the windscreen. If the windshield was replaced, the camera system must be re-calibrated. Changing the shape or angle of the window could affect how the cameras are positioned and, by extension, how accurate the pre sense system is.
4. Disconnect and Reconnect the Battery
Take the car’s battery out and leave it alone for a few minutes. Then, reconnect it to clear the system. This could help you reset the system and get rid of any error codes that were saved.
Contacting a workshop or having a trained Audi expert fix this is better. But if you want to do it yourself, these steps should be taken to address the malfunctioning Audi Pre-Sense Fault.
Where is my Audi Pre Sense Sensor Located?
The Audi pre sense sensors may be placed in a different place depending on the type and year of your Audi. But the Pre Sense devices are usually put around the car to help keep it safe by finding any risks. There are a lot of Pre Sense sensors in these places.
| Sensor Location | Description |
| Front Bumper | Detects obstacles ahead for collision prevention |
| Rear Bumper | Detects objects behind for parking assistance |
| Side Mirrors | Monitors blind spots for lane change assistance |
| Windshield | Detects rain and forward collisions |
| Interior | Monitors occupants for safety features |
Conclusion
The Audi Pre Sense Fault Alert helps you know that there is a problem with the car’s safety system. A trained professional needs to look at this issue immediately to identify and fix it. Ignoring the warning could put safety features at risk, showing how important it is to fix things immediately for best performance and road safety.
