This tech does not always work as intended and does not respond quickly enough, no matter how hard Audi tries. “Audi Pre Sense Currently Restricted” is the message that will appear on your vehicle’s screen while the Pre-sense technology is malfunctioning. Consult the handbook provided by the manufacturer. Where do these problems originate from? What is Audi pre sense? What follows is a list of symptoms, reasons, types, and ways to fix the problem.
Why Pre-Sense And Its Detectors Are Important
Audi’s pre sense technology detects possible problems and dangers. The system will intervene to fix problems before they cause an accident to happen. Audi provides a variety of pre-sense detecting functions, including front, rear, or 360 degrees. Just as the Audi starts to skid, the Pre-sense system will send a signal to the stabilisation Control (ESC) in the event that the driver loses control of the car.
The pre-sense technology will alert the motorist audibly and visually. To prevent an accident or overturn, the system can apply partial or complete braking assistance, depending on the situation.
Upon using the brakes, the system will proceed to close the side windows and sliding sunroof, activate the hazard lights, and turn them on. Additionally, the front passenger and driver will be able to restrict their forward and sideways movement by tightening the grip of their seatbelts. To avoid serious injuries, it is important to restrict the movement of the driver and passengers.
Indicators of Audi Pre Sense Malfunction
Dashboard indicators will be shown in the event of a pre-sense system breakdown. Circles and brackets topped with a red star represent the warning symbols. Another possible shape for the indication is a yellow triangle with an exclamation point in the middle of a broken circle.
Both of these alerts indicate that something is wrong with the pre-sense system. From faulty sensors to an excess of dirt, there are several potential causes for the system to fail. The solution is simple: just take your vehicle to the car wash. Call an expert if the dashboard warning lights don’t go away.
What Are the Types of Audi Pre Sense?
It is vital to grasp the differences between the several types of pre sense before delving into its operation.
Fundamental Presense
The pre sense simple version is the standard version of Audi pre sense. This update triggers the control unit’s intervention in the event of an abrupt braking or skidding incident by utilising the vehicle’s electronic stability programme (ESP) sensors. It starts shutting all the windows and the sunroof and turns on the danger warning lights as needed. The front seatbelts and pneumatic springs are also tensioned by the vehicle. If an accident does not happen, the little electric motors that cause this reversible tensioning procedure release it.
Pre Sense Front
Another model, Audi pre sense front, can identify frontal crashes and offers variable degrees of driver assistance based on the severity of the impact. The first is a simple warning light that flashes on the dashboard and makes an audible noise to let the driver know something is wrong; the second is a secondary warning jerk that the car makes when it briefly brakes. The driver can use the car’s brake assist system to slow down the vehicle as soon as they press down on the brake pedal. Partial braking, the third step of avoidance, happens if the driver does nothing. The car responds instantly and is brought to a stop using about a third of the effort applied to the brake pedal. At long last, the sunroof and windows start to close, the danger lights go on, and everyone buckles in.
Pre Sense Rear
The Audi pre sense rear system lessens the impact of a rear-end accident by utilizing the vehicle’s rear sensors. Even here, it locks the sunroof and windows and tightens the seatbelts at the same time. In the case of an accident, the front memory seats, which are available, will also adjust to a better position.
Pre Sense Plus
The final version, Audi pre sense plus, introduces a fourth step of avoidance. Following the exhaustion of all other alternatives, the vehicle will undergo a second cycle of mild partial braking, after which the seatbelts will be fully tightened during maximum braking. Around thirty seconds before contact, this happens, and then it’s too late to avert a collision. With pre-sense plus, you may slow down your car by as much as 40 km/h before a collision, reducing the severity of the damage.
Causes Of Audi Pre Sense Warning And Its Solutions
Fault In The Pressure Sensor
The pressure sensor in an Audi vehicle measures the air pressure in the tyres and can identify when a tyre is low on air. If this sensor is malfunctioning, Audi’s computer system will be notified that the tyre pressure is incorrect. Because there isn’t enough pressure, your automobile won’t function as well, and you can have trouble braking correctly.
First, make sure the sensors are working properly. It is possible that the sensors are not functioning properly since the owner of the car may have recently replaced the tyres without properly adjusting the sensors.
The tyres’ positions could impact the data from the sensor. If the tyre sensor provides inaccurate readings, it might compromise the functionality of other systems in the Audi. It is necessary to replace the sensors.
Brake Line Damage
Damaged brake lines are another typical problem with Audi vehicles. Broken brake lines must be replaced. It prevents the motorist from reacting when they attempt to brake.
For instance, under rainy conditions, it is common for a vehicle to skid just before using the brakes.
The Audi pre sense system uses its high-tech sensors to help the driver avoid a skid in this kind of circumstance by applying the brakes automatically.
The mechanism is useful for keeping the car under control. However, the data read by the sensors will be affected when brake lines are broken. The brakes won’t work because of a technical issue.
The brake lines need to be changed by a skilled mechanic. The brake lines that the mechanic installs on your Audi must be an exact fit. Audis will perform better in the long run if their brake lines are a perfect fit.
Fault In The Flash Memory Module
The flash memory module controls the Audi pre-sense and emergency braking systems. When the module system fails, it cuts off all communication with the rest of the vehicle’s computer network. Still, it’s capable of causing a plethora of issues, such as a breakdown that stops the pre-sense system from transmitting messages. This problem could develop if the battery is repeatedly removed from the vehicle, whether for servicing purposes or otherwise. A damaged flash memory is the cause of this system error.
The driver’s attention is required because this matter has the potential to impact the tyre pressure system. This issue may also impact other computer system operations that depend on a pre-sense control system.
You can fix Audi pre sense warning light issue by upgrading its Engine Control Unit. By “updating the system,” we mean installing the most current version of Audi’s software. The ODIS Service diagnostic tool is necessary for this task. All impacted vehicles are required to apply a software patch that Audi has published to avoid future occurrences of this problem. Nevertheless, prior to removing the Audi battery, you need to obtain the software patch. Failure to apply the update might result in the need to replace the engine control module.
Short Circuit
The pre-sensor system could become inoperable due to a broken cable. There is wiring under the passenger seat for the pre-sensor system. The airbags are activated to prevent the vehicle from collapsing when a sensor receives 5V from the wire.
Damage to this wire can trigger the Audi pre-sense system, rendering it inoperable. The vehicle loses its ability to anticipate potential dangers if the pre-sensor system fails.
This problem has an easy solution. The pre-sense system will function properly once again when you replace the cables.
Too Much Dirt On Sensors
For proper operation, the sensors require adequate room. In this area, cars may be seen from farther away. The sensors will be unable to pick up signals if they are covered in dirt. Inadvertently, this might set off an Audi pre sense system fault. At daylight, turn off all headlights and taillights to see whether it works. Every six months, take your Audi in for maintenance. Maintaining your vehicle’s computer system and sensors with regular service can keep them in top shape.
Go to an Audi professional repair immediately if you hear voices coming from your detectors; they will need to examine the software.
The Problem With The Front Camera
The pre-sense system relies on the front camera to sense different hazards that can cause accidents. The camera can detect changing signal lights or if the car in front of the Audi is slowing down.
If the camera fails to detect minor objects, especially in sharp u-turns, the computer gets confused and causes pre-sense malfunction. It would be best to replace the camera with a brand-new Audi camera. Make sure an Audi specialist mechanic does this procedure.
Conclusion
The Audi Pre Sense technology is a semi-autonomous safety system that interacts with automatic braking or other collision avoidance systems. It can command the brakes, windows, and sunroof and even tighten the seatbelts, which prevents severe injury to passengers in the event of a collision. Now you know the causes of Audi pre sense warning and how it works. If you found this problem in your Audi try to contact the mechanic or specialist.
