You just need to reset the aircon error with vcds or similar and the mileage will go. If the error occurs again it will be with the new mileage

if error is present you cant erase it so old km still remain.

Yes because it is internal eror and you can not erase eror at all,change another ecu for hvac or try to repair

seem that your have a real hardware problem.
so error is permanent and can not be erased.

as said , better to look for another hvac unit

on audi a8 2005 I have same problem, but with parking brakes,
the car was have 200000km , then i change km in 120000km,
but the errors stay in 200000,
then put in dash 999980, and drive mre then 20km, then I do again the dash to 120000km,
and in parking brake modul its come error with 0km!!!!

I dont know if it will works on your audi,
but better SAVE original eeprom, and then try to do like me
and if you do good job on this car,
say coustomer he maybe have Garanty for car to 3 years

I was do this car on OBD
