This message appears on Audi Q3s with an automatic gearbox if you try to start the engine without first pressing the brake pedal.

This message will appear if you try to start or switch off the engine when the selector lever is not in N or P. The engine can then not be started or switched off.
Key not in Audi Q3?
If the indicator lamp lights up and the message appears, the convenience key* was removed from the Audi Q3 while the engine was running. If the convenience key is not in the Audi Q3 you will not be able to switch on the ignition or restart the engine after it has been switched off. You will also not be able to lock the Audi Q3 from the outside.
Shift to P, Audi Q3 can roll away. Doors can only be locked in P.
For safety reasons, this message will appear together with a warning tone if the selector lever is not in position P when you switch off the ignition. Put the selector lever in position P; otherwise the Audi Q3 can roll away and cannot be locked.
No key identified. See owner's manual.
This message appears if there is no convenience key* inside the Audi Q3 or if the system cannot detect or identify the key. This can happen, for example, if the radio signal from the key is obstructed by a metal briefcase or similar, or if the key battery is weak. Electronic equipment, such as mobile phones, can also interfere with the radio signal from the key.
The engine can still be started or stopped if this happens (please refer to Link).
