DEF tank faults

Hey guys I just recently got some fault codes in relates to the DEF tank. Possibly a wiring issue or should I just replace the DEF tank? When I clear the codes the fault stay pending and I'm assuming because it's gotta go through the monitoring before it really clears.

P203A
P205B
P205C

Some times I get close to about 6 faults, but it's only showing 3 for now and it's all related to the DEF tank.

The DEF tank costs $1200. You may still be covered by the 10Y/120K mile extended warranty, but hurry.

There is information in the diesel subforum on how to fix a couple of individual components in the DEF tank.

Taking mine in service soon to get the DEF tank replace. Been getting faults as well.

Use to have SEL light on but that was remedied by topping off my exhaust fluid.

My 10YR/120K is done unfortunately, but my friend can get me a DEF tank for around $800 with his discount.
