KLIMA error 9c54 - AUC sensor

[mrfochon]

Having an issue lately where the AC and even the regular air is totally off.
INPA showing error 9c54 stored - no signal from AUC sensor.

Anyone knows where is that sensor ?
I have tried to find it with schematics and google images but its is not near the air filter on the passenger side under the hood.

Thank you

Adding some pictures as I m genuinely wondering where it has gone 😂

It’s supposed to be on the filter box. It’s not.
I checked under. It’s not.

So must be somewhere else ..
