Proud new owner... and already a CEL

So after searching for months I finally found what I was looking for two weeks ago, 2011 alpine white Msport w/55k! Loving the car, and was already aware of the emissions problems that plague these cars. Coming from a fully deleted and built Mk6 TDI I had everything planned out to do the ABC delete and tune plus a big IC ext ext in a few months. But went to start it up today and got the P205b code... From my understanding this is the urea tank temp sensor. My question is would driving with this for a month or so affect anything, or is there a way to tune out the DEF system before doing the rest of the deletes?

You have to reset it every 100 miles because it can throw the "No Start" message because of that...

I thought I was ready but this is hardly the first date... lol. Well Im glad to know this can cause a no start, guess nows as good a time as any to download the Carly app so I can keep resetting. I really don't want to dump any money into this tank if i can avoid it, being that I don't plan on needing it in the near future (unless its full of methonal). Im going to try flushing the tank with hot water and hope it stays off for a awhile.. If the sensor is still not working do I have to worry the DEF freezing at the beginning of the winter here, I live in minnesota... It gets cold quick?

The DS wires need to be moved out or they WILL break matter of time! Just fixed mine yesterday they were on thier way! Easy tho! Dont remove the whole shifter just the console trim.
