What is your question?
I have a 2010 Audi A4 Avant Quattro. My air-conditioning doesn’t seem to work when my car is hot (hot being – that the air outside is 70+ degrees) or when it’s cool outside and I’m going under 60mph. When it is night time or cool outside and I am going more than 60 miles an hour, my AC works great. How can I resolve this issue on my own?
What makes this problem better or worse?
Problem is better when moving 60+ mph & low temperature outside
How long has your 2010 Audi A4 Quattro had this problem?
Months

Knee jerk reaction if you have issues with air conditioning when moving slower is that your condenser fan may not be turning on. However, this Is a guess, and lower ambient temperatures can make the system seem like it is running. Air conditioning problems can originate by one of the following general areas: 1) A problem with the refrigerant system. Meaning, the refrigerant used has escaped and there is not sufficient refrigerant to pressurize the system properly, resulting in hot air. When this happens, the system must be checked for leaks, the leaks repaired, and the system recharged. 2) A problem mechanically or electrically with the under hood components. If the compressor has failed, it will not allow the system to operate. Further, if the system becomes contaminated with debris from a failed compressor, this can be even worse. Electrically, the coil of the compressor may not be working properly, or a cycle switch could fail preventing the system from operating. If your condenser fan is not working, the system may not work properly also. 3) Climate control problem inside the vehicle. If the system that operates the heating, ventilation and air conditioning system fails to operate properly, then the under hood components may not be turned on or off properly, keeping the cold air from being produced. Only testing these systems will yield a direction and an eventual result.
