Default Help with ecu location pls

Still fighting with my auto light/wipers issue
No one knows whats wrong.....not surprised there I guess
Could you guys point me ecu's location for above?
Don't have a clue how to locate the fault
Frustrated beyond frustrated
All coding is correct, no faults, new rain/light sensor fitted
I thought that the windscreen is incorrect but after close inspection all serial numbers are matching rest of the cars glass
Did the s8 originally had sun visor, my next question?
Properly

This ECU is located behind the glovebox, next to or very near to the CAN gateway.

Part number is 4E0910279(revision letter) if you need a new one.

hope you get it sorted

Hi Borys,

If all is fine with J519 (09 - Central Electronics) there maybe a fault with the wiper motor control unit J400 or wiring in between. J400 is a slave from J519 and controlled via LIN. The physical wiring between J519 and J400 is from plug C (that's the 32pin connector)

J400 is one complete unit with the wiper motor. Have you replaced this in the past?

No never touched by me
Problem lies with auto lights as well, they are on all the time no matter if dark or day light
Was hoping that there is an ecu which control both as the rain/light sensor
