Audi A6 Air condition problem

Hi all.

Car: Audi A6 Avant 2007 2.0tdi bre

Would anyone have any information on what could be a problem with the air conditioning. The air conditioning stopped working and a leaking pressure sensor was found to be a problem. After the new sensor, the car emits a DTC P1641. When looking at the data list it shows AC pressure all the time at 50bar ...

Any help welcome
