I have a 2013 Passat TDI that's throwing fits about the Adblue level. The tank is full, but it reads "150 miles to no start".... common old story. I'm thinking of doing a delete but thought I'd post my scan results here to see if anyone sees anything else that could be the problem before I go do it. Here are the engine codes I got:

Looks like its a wiring concern just from looking at those faults. They all came on at the same time. Couple of them are short to ground faults and the one for the level sensor says Electrical Malfunction. I would check the wiring to these components, Theres two big connectors at the back where the tank is. Check for power and ground. Seems like your fan modules are affect as well.

They all came on at once because I cleared the codes and this is what came back.

Maybe check the fuses as well to see if any is blown. Off the top of my head, I dont know whats all on the circuit.
