I know there is not alot of late model Diesel enthusiasts here but I thought I would ask..

Anyone know if you can purchase individual components in the AdBlue tank? I have a Fault code of 203D17 (which says Fill Level "AdBlue" short circuit to positive). I think the issue may be in the level sending unit or the sub harness at the tank. In the DAS it gives some resistance levels for the various levels of the tank which I will check as well however I was looking in EPC and only see the tank listed as a unit. I also see in EPC a tank heater repair kit?

Anyone been down this road yet?

The SCR/NOx simulator is looking pretty good as well!!
