heating circuit downstream oxygen sensor P0141

Hello everyone,

I recently read out the data from a facelifted RS3 with 400 horsepower.
The error is:

17138 - Bank 1, Probe 2; Heating circuit.
P0141 00 [237] - Electrical fault.
Warning light ON - confirmed - checked since last reset.

During the diagnostic test with VCDS, the value of the post-catalytic converter sensor ranged from approximately 250 ohms to 130,000 ohms.
Can the spread be that extreme?

Does anyone have an idea?

After deleting the error, it reappears again after 15-20 kilometers.

greetings
