Washer fluid warning doesn't work

[notorious]

When washer reservoir is empty I get no beep/warning on facelist D2. Is the sensor dead or should I look somewhere else first?

Instrument cluster coding is 00483. Is this correct for a8s? Tried to code 04483 to software enable the washer fluid warning, but this code is not accepted. Can anyone with ELSA post the possible code combinations for instrument cluster please?

Also, can seatbelts warning be enabled on UK cars? Feel without my element here in this car... Ding Ding Ding...

It was loose connection from the rear of dash panel insert. Removed the insert and tighgtened socket connection. Works now.
