    Exclamation A6 C7/4G Lights humidity sensor ?

    Hi

    For some time I see that my driving lights are on during normal sunny day.
    Also on autoroute where there is limit during rain - sign recognition shows my a limit for a rain.
    Navi don't go dark (night/tunnel)
    Lights on speedometer are on.

    I suspect humidity sensor - or something similar.

    No errors are shown in any module.

    What was done recently in a car ?
    Update of MMI from 928 to 1425.

    I scan is necessary I will provide one.

    Could you tell me in which module (09, 46?) I can see actual humidity used for detection of rain ?

    We'll definitely need you to post an Auto-Scan.

    That should also show the humidity sensor as a slave module
