Image recording

Surrounding area monitoring

Applies to: vehicles with surrounding area monitoring

Some vehicle functions require the vehicle's path to be detected and evaluated. This is done by cameras installed permanently on the vehicle that detect objects in the vehicle's surroundings (such as obstacles or guard rails). The live images from the cameras are transmitted to the applicable control module.

The camera images are transferred to the responsible control module for processing and may be stored, depending on vehicle equipment. The control module analyzes the current camera image using image evaluation software. This image evaluation software detects anonymized technical measurements, such as distances to objects.

The control module evaluates these technical measurements and makes it possible for the assist systems to control the vehicle as needed.

Data memories

Vehicle control modules

Data memories
Fig. 187 Driver's side footwell: connection port for the On Board Diagnostic System (OBD)

Your vehicle is equipped with electronic control modules for various vehicle systems such as the airbags. These vehicle control modules store data while driving normally that is required by an authorized Audi dealer or authorized Audi Service Facility for diagnosis and repair purposes. Only certain types of data are recorded for a very short period of time if a control module has detected a system event. No noises, conversations, or images will be recorded in the vehicle.

The data may include information such as the vehicle speed, the direction of travel, and information about the brake system, or also the behavior of the restraint system in the event of an accident.

The stored data can be exported and downloaded with special devices, which must be connected directly to the vehicle.

On Board Diagnostic System (OBD)

There is a diagnostic connector socket in the driver's side footwell to read out the various control modules and the event data recorder. Data regarding the function and condition of the electronic control modules is stored in the event memory. Only have an authorized Audi dealer or authorized Audi Service Facility read out and delete the event memory.


  • Incorrect use of the connection port for the On Board Diagnostic System can cause malfunctions, which can then result in accidents and serious injuries.
  • Only allow an authorized Audi dealer or authorized Audi Service Facility to read out the motor data.

Crash Data Recorder

Event Data Recorder

This vehicle is equipped with an Event Data Recorder (EDR). The main purpose of an EDR is to record, in certain crash or near crash-like situations, such as an airbag deployment or hitting a road obstacle, data that will assist in understanding how a vehicle's system performed. The EDR is designed to record data related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less. The EDR in this vehicle is designed to record such data as:

  • How various systems in your vehicle were operating;
  • Whether or not the driver and passenger safety belts were buckled/fastened;
  • How far (if at all) the driver was depressing the accelerator and/or brake pedal; and,
  • How fast the vehicle was traveling.

These data can help provide a better understanding of the circumstances in which crashes and injuries occur. NOTE: EDR data are recorded by your vehicle only ifa non-trivial crash situation occurs; no data are recorded by the EDR under normal driving conditions and no personal data (e.g. name, gender, age, and crash location) are recorded.

However, other parties, such as law enforcement, could combine the EDR data with the type of personally identifying data routinely acquired during a crash investigation.

To read data recorded by an EDR, special equipment is required, and access to the vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties, such as law enforcement, that have the special equipment, can read the information if they have access to the vehicle or the EDR.

Data usage

Audi can read out the information stored in the data memories or similar data, or give this information to third parties, especially in the following situations:

  • If the vehicle owner or lessee agrees
  • If there is an official request from the police
  • If a court or authorities request it

If legally permitted, Audi can also use the data for analysis of vehicle operation and safety performance or provide this data to third parties for research purposes.
