Customer states:

After driving for a while, the following message is displayed on the MMI display: "Loading system. Please wait..." (see Figure 1).
When this message appears, the MMI system can no longer be operated via the display.
The MMI system continues to run in the background and audio is output.
The system can be operated using the multifunction steering wheel controls.

Workshop findings:

The customer complaint cannot always be reproduced as this behavior only occurs after driving for a while.
The message remains active for the entire bus cycle until the vehicle is stationary and parked for an extended period of time.
The MMI functions normally without any issues the next time the vehicle is used.

NOTE: If the message "Loading the system. Please wait..." only appears for a short time after starting the system, this PSS does not apply.
