Rpm sensors problem

Hello, I have a problem with my CLS w219. The live parameters show these numbers and they do not change when stationary or driving. The ABS and ESP systems are working, but the steering wheel is much heavier. Where should I look for the problem?

Sounds like a CAN or module issue -
My suggestions:

disconnect battery for 10 mins
turn wheel lock to lock several times
clear codes
check the ESP module connections for water / corrosion

good luck and let us please know what it is when you solve it!
