Audi A3 8L Fuel Gauge Issue: Incorrect Fuel Level Indication - Vag-Com Diagnostic & Adjustments

Hello
I have a problem with the correct indication of the fuel level, I know that the topic is rolled, but I have read a lot on various forums and I can not read anything about this problem. The point is that when I refuel the car fully, the pointer on the fuel gauge leans to the maximum to the right (i.e. for the indication 1/1) when I do 700-800 km, the pointer drops to a value a little below 1/2 and points to the reserve for Fis.
After connecting the Vag to the car, when it was fueled with FULL, the counter 17/30 was 121 (the adjustment range was from 120-130).

I will add a scan from the car and there is some error in module 17:

Do the indicator test a few times, maybe the motor itself is damaged ...

When I do the test of tips, all but the one from the fuel are nicely vertical, and the one from the fuel shows 3/4. Alternatively, can the motor itself be replaced in the meter ??

Of course it is possible ...

Poorly seated needle or motor damaged. In case of what I can replace
