Does anyone have experience correcting the issue associated with the trouble code P20EE?

The trouble light on my 2011 Touareg TDI came on and my ODB scanner is showing code P20EE which is the NOx sensor. From what I've read the problem is either the NOx sensor reading incorrectly or the diesel exhaust fluid pump not pumping correctly.

I live in California so I need to get the car to pass the ODB portion of the smog test so I can get it registered. My car is also part of the group that will be bought back by VW. It turns out VW requires a valid vehicle registration on vehicles being bought back.

I have 100,000 miles on the car.

Thanks for your assistance.
