Comfort Control Module

[Forey1000]

Seen so many forums for this but none of them give a straight answer, I cannot find the location of the module anywhere?? 

Car is a 2008 Audi A3 1.9TDI SE

Carista showing error 00003 Locking Module and 01038 Central locking thermal protection  

Any ideas? 

Thanks

What is comfort control? Air con, seat position, something else?

I had never heard of Carista so I looked it up and it appears your car is not supported: https://caristaapp.com/vehicles/audi/a3
