Have A6 with sign recognition (2015)
recently fiber receiver on MIB2 died making my MIB2 reset every 10-20sec.
decided to replace it instead of repair and to make flash to newest train.

All is fine, except sign recognition and choice of Rain State, Sunny State by sign recognition.

For counties like Belgium or Luxembourg there are 2 permanent speed limit
ex. Luxembourg
130 when not raining
110 when raining

My sign recognition shows always limit for wet condition.
as below:

I know that navigation is providing data about 2 signs.

So my question how it is chosen to display WET condition signs or SUNNY condition signs.

I'm thinking about
PSD version (1.4 vs 1.5)
Some humidity sensor
