Oh boy did this send me down a rabbit hole!!
Found this part number for that part:
5Q0131940 - Sensor Module
What a vague part, it seems to only come with the tank and even more strange is it's not on all tanks.
From ETKA, it seems to be connected to the Euro 6 Plus PR code but not 100% on that and with so little info, it's hard to say.
Could be a heater, level sensor, in tank Kraken detection...
Then I looked through the wiring diagrams... It was wires so must be on the diagram, right?
It is!! G849 Adblue quality sensor. So, there you go.
