How Air Conditioning Works
Audi air conditioning plays a vital role in driver and passenger comfort all year round.
AC helps to eliminate fogging on the windows and keeps your view clear at all times during winter months. In the summer, it aids in reducing humidity and keeps you cool.
Here is what Audi air conditioning systems are typically made up of:
- Compressor: A belt driven by the engine powers the compressor, the initial component of the system. The compressor has the job of heating and cooling the system while compressing and circulating refrigerant gas.
- Refrigerant: The refrigerant is crucial for air conditioning. It absorbs heat from inside the vehicle and releases it outside.
- Condenser: Positioned in front of the radiator, the condenser receives refrigerant from the compressor. As the refrigerant passes through the condenser, it releases heat and transforms into a high-pressure liquid.
- Expansion Valve: Liquid refrigerant from the condenser moves to the expansion valve. This valve reduces the pressure and temperature of the refrigerant, preparing it for evaporation.
- Evaporator: Typically found inside the dashboard, the evaporator absorbs heat from the surrounding atmosphere when the refrigerant enters. Consequently, the blown air into the cabin becomes cooler.
- Blower Motor: The blower motor circulates cooled air throughout the cabin, ensuring a comfortable and cool environment.
- Cycle: The air inside the car undergoes continuous cooling and dehumidification using the air conditioning system to achieve the desired temperature.

In simple terms, this is how air conditioning works. Some features and performances of Audi air conditioning may be different to this setup, but this is a general overview. Either way, routine maintenance and servicing are vital to ensure that your air conditioning works reliably every time.

Signs Your Audi Air Conditioning System is Failing
Lots of factors affect the air conditioning system in your Audi. Keep your eye out for signs of wear or faults.
Ask yourself the following three questions when identifying issues with your Audi air conditioning system:
What’s the temperature of the air coming out?
If the air coming out of your air conditioning vents isn’t the correct temperature, the system might be losing refrigerant.
Refrigerant hoses typically use rubber or synthetic materials. However, there’s a natural loss of refrigerant through these materials, which could be up to 10% per year. If the system isn’t used regularly, the loss might be even higher.
Is the air conditioning system blowing air?
If your air conditioning system doesn’t produce any airflow after setting it to the maximum, there might be an issue with the electrical switch. Most manufacturers recommend a full service instead of just re-gassing if you’re having air-conditioning problems. As part of the air conditioning service at Fergies, we go through a 27-point checklist to find the root cause.
Is there a strange smell in the air?
Your Audi’s air conditioning system might give off an unpleasant smell due to factors like moisture, clogged air filters, mould, mildew, or refrigerant leaks.
During our Air Conditioning services, we replace the cabin air filter, clean the air intake vents, and remove debris and deodorise the cabin to help eliminate the bacteria.
We recommend that you seek professional advice and assistance when you have air conditioning system issues. At Fergies, we have an expert team on hand to diagnose and repair your Audi air conditioning system.
Troubleshooting Problems With Audi Air Conditioning
It can take time and effort to diagnose Audi air conditioning problems, needing expert knowledge and tools. You might be tempted to do the work yourself, but we advise against it as you may cause further damage.
Without the right skills or experience, your Audi air conditioning system is at risk of further issues. With high-pressure and environmentally damaging refrigerants, you can get yourself injured. Reach out to our team of Audi air con experts at Fergies to handle repairs properly.
Environmental impact could also be high if you attempt to replace refrigerant yourself. With strict UK regulations on handling refrigerants, improper handling could result in damage to the ozone layer.
In our workshop, we always practise the safe handling of environmentally damaging materials such as refrigerants. Choosing us ensures your waste materials are handled responsibly.
We have the expert knowledge, tools, and experience when it comes to diagnosing and repairing your air conditioning system. We help get our customer vehicles back working like new and help protect the environment in the process.

How To Prevent Audi Air Conditioning Issues
Proper maintenance of your air conditioning system needs a proactive approach and regular maintenance.
Here’s how to prevent air con problems in your Audi:
- Use the air conditioning system regularly: Keep it working smoothly by lubricating its parts regularly.
- Keep a close eye on the system: Look for any damage, like leaks or worn-out parts. Get in touch with a qualified technician to fix any problems.
- Be responsible when using the system: If it’s too cold, the system works extra hard. It’s better to set the temperature at the right level for better efficiency.
- Avoid using it too much: Using the air conditioning system too often or when not needed can make it wear out faster. Using it sensibly keeps it in good shape.
- Park in shaded spots: When you can, park your Audi in a shaded place to shield the air conditioning compressor from extreme heat. Even in the UK’s milder summers, this helps.
- Do regular maintenance: Taking care of your Audi’s air conditioning system can prevent big problems. Check the cabin air filter for leaks and change it as needed.
The above guide will help reduce air conditioning issues in your Audi. It will also ensure you and your passengers are comfortable all year round.
