How do I fix the inconsistent temperature control in my Audi 80?

I've noticed that my Audi 80's temperature control doesn't seem to accurately reflect the temperature inside the car. It can vary by several degrees and it's quite frustrating to constantly adjust it. How can I fix this issue?

First, try checking the coolant levels in your vehicle. A low level can cause temperature inconsistencies. If that doesn't work, it may be an issue with the temperature sensor, which can be easily replaced by a mechanic.
