The complaint occurs only when switching on the MMI.
Technical background
Software-related failure on MMI screens with the part number 8F0 919 604.
Production change
A new screen has been introduced.
Measure
Check with a screenshot whether the control unit for information electronics still sends a picture to the screen.
1. Insert an SD card in the card reader of the control unit for information electronics.
2. Press and hold the buttons till the button lights start to flash.
3. Remove the SD card and insert it in the card reader of a PC.
4. Open the picture file (.png format) on the PC.
5. If the picture shows an MMI menu, the control unit for information electronics is correct.
6. Check whether a screen with part number 8F0 919 604 is fitted. In diagnosis address 5F under "DU7 High" this part number is shown as sub-bus system.
7. As immediate measure and to have a display on the screen cool down the passenger compartment. Restart the MMI. Now the display works till the MMI is again started at very high temperatures.
8. After the cooling down update the MMI3G software according to TPI 2019922.

Replacing the screen does not cure the complaint.
