Rain Sensor: Detect Rain with ID

Hello!

Does anyone know if the values for the rain sensor are available on the Comfort CAN bus?
VW Touran 2011, information that can be read.
My assumption is that the message with CAN ID 5D1 is the one, but the values for...
Bytes 3 and 4 are always the same: 10000000 01110010.

Perhaps someone here can help me.

Thank you.

Franz.
