2021-2022 Audi Pre Sense Restricted Function Warning

Some 2021-2022 Audi owners may notice a warning icon indicating "Audi pre sense not available at the moment" or "Audi pre sense restricted function" immediately after starting their vehicle. This icon typically appears for about 20 seconds before disappearing. This behavior is addressed by Audi Technical Service Bulletin 90 20 68 2059891/2.

The TSB clarifies that this is not a malfunction but rather a normal part of the system's startup process. The front camera for driver assist systems, identified as R242, requires a brief period to initialize.

Symptoms

Owners of affected vehicles may observe the following:

• An icon displaying "Audi pre sense not available at the moment" or "Audi pre sense - restricted function icon is displayed after engine starts" appears on the instrument cluster.
• The warning icon typically remains visible for approximately 20 seconds after the engine is started.
• In some models, the vehicle may need to move a short distance before the initialization indicator disappears.
• The icon then clears on its own, and the Audi pre sense system functions normally.

Fault codes / DTCs

This informational bulletin does not specify any Diagnostic Trouble Codes (DTCs) associated with the "Audi pre sense restricted function" warning. The condition described is considered normal operational behavior rather than a fault requiring a code.

What the service bulletin says

Technical Service Bulletin 90 20 68 2059891/2, which supersedes an earlier bulletin (20-54), explains the reason for the pre sense warning. It states that the front camera for driver assist systems (R242), which is a multifunction camera, requires about 20 seconds to power up and become fully operational after the ignition is switched on. In some cases, a velocity signal (meaning the vehicle starts moving) is also needed for the system to fully initialize.

Because this is a normal startup sequence for the system, no repair is necessary. The bulletin advises service technicians not to perform any repairs for this concern, as it is considered normal behavior. Further information on this system can be found in Self-Study Program 970363 – 2017 Audi Q7 Occupant Protection and Infotainment System.

What to do

If your 2021-2022 Audi displays the "Audi e-tron pre sense restricted function" warning for a short period after starting, there is no need for concern or repair. This is normal operation as the system's front camera initializes. You do not need to take your vehicle to a dealership for this specific issue.

If the warning persists for longer than 20 seconds, does not disappear after driving, or is accompanied by other symptoms, then it would be advisable to have your vehicle inspected by a qualified service technician.
