Do you have any news on how the problem was solved?
Just wondering.

I had a similar situation and replaced those 2 sensors, then decided to programmatically disable the AdBlue system completely without removing the DPF filter.

Bought an OBD plug from OBDTUNE dot com, brilliantly simple solution to AdBlue problems. For opponents of a complete shutdown, the team created an OBD plug that can reset AdBlue errors - it's the kind of solution where you don't have to call a tow truck if you're stuck in the middle of the road away from the dealer, and will help solve problems temporarily and drive to the dealer in peace. Doesn't disable AdBlue, so it's completely legal.
