Hello

today a strange thing happened, MMI 3G HIGH stopped starting - black screen and no backlight of buttons next to the shift lever, a month ago I had a similar symptom, after some time it unlocked by itself

I performed a reset, the HDD can be heard that it responds

nothing was uploaded


VCDS shows the diagnosis:




what ideas do you have?

What are the errors from the 5 modules showing errors in the VCDS scan? (Preferably in English)

I checked all the fuses .... I disconnected all connections regarding the radio, amplifier, and the entire rear unit ..... MMi has been revived and in addition the b & o sound system sounds much better .... (Probably something has restarted) no reaction MMi - fault probably lies in the temperature change, from -14C "it was + 4C the next day" ....



the tailgate also stopped working .... When the rain stops, I check the plug connections



I noticed that the navigation in MMi does not work, it does not even detect the navigation database ....



How to clean the navigation activator?
