How do I make my A4 Quattro air conditioning colder?

For starters, use a sun-blocking shade in the windshield while you’re parked, or look for a shady parking spot. Closing all the passenger vents in your car can help redirect cold air toward you, cooling you off faster. Still need more chill? Head to Firestone Complete Auto Care for an A/C performance check and recharge.

Why is my A4 Quattro A/C blowing hot air?

An A/C blowing hot air has several possible root causes. There could be an issue with your compressor clutch, a blown fuse, a leak, or a clog in the expansion valve.

How does my A/C system get a leak?

Over the years, the rubber seals and gaskets in your A4 Quattro’s A/C system naturally degrade. Moisture can get into the system and cause a malfunction, or parts can simply wear out so that your system no longer seals properly.

Does my A4 Quattro A/C run on gas?

A4 Quattro air conditioning systems don’t use gasoline as a direct fuel source. However, they do rely on engine power, which can indirectly affect your vehicle’s gas mileage.

My A4 Quattro’s A/C smells like vinegar! What can cause that?

If a vinegar-like odor comes from your A/C, bacteria growth could be the culprit. Moisture accumulation in the air conditioning system of your A4 Quattro creates a breeding environment for microorganisms.

Why does my A4 Quattro’s A/C only work when the car is moving?

If your A/C only works when the vehicle is moving, there could be a problem with part of your A4 Quattro’s A/C or electrical system. Potential issues include low coolant or a faulty cooling fan.

A/C Service for Audi A4 Quattro

Few things are worse than a broken car air conditioner on a hot summer day. Your steering wheel feels like lava. Sweat soaks the driver's seat. “Who can fix my Audi A4 Quattro A/C?” you wonder, as the sun beats through the windshield. Firestone Complete Auto Care — that’s who! We’ve got experience with Audi vehicles, and our qualified technicians can diagnose and service the A/C system in your 2009 Audi. Come to your local Firestone Complete Auto Care in your Audi A4 Quattro

During this initial A/C performance check, we’ll look at the state of your 2009 Audi A4 Quattro’s A/C system to determine whether repair work is needed. We’ll test overall system performance, check for any leaks, and measure the system pressure. If any signs point to a possible leak, we’ll send a special U/V dye through the system, or use something called a “sniffer.” A "sniffer" is a machine that's run along parts of your Audi A4 Quattro A/C system that can identify points where refrigerant fumes could be escaping the system. If there's a leak, we'll find it and fix it.

A4 Quattro A/C Recharge

While your 2009 Audi A4 Quattro’s air conditioner is being serviced, we’ll also do an A/C evacuation and recharge. To start this process, a technician will flush out the old refrigerant from your vehicle’s A/C system. Then, they’ll perform an evacuation (also known as a discharge) on the entire system per Audi guidelines. Finally, we’ll recharge the A/C system with new refrigerant and after one final test to be sure the system is cooling properly, you're ready to get back on the road. We want you to be comfortable in your car, so we train our technicians to perform 2009 Audi A4 Quattro A/C recharges.

Common Audi A4 Quattro A/C Problems

Warm air isn't the only Audi A4 Quattro A/C problem you may encounter. Another common A/C problem is weak airflow, which could indicate an old ventilation fan, a seal or hose that needs replacing, or mold buildup in your A/C system. An A/C system that starts off blowing cold air but then turns warm may be due to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 2009 Audi A4 Quattro? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Our technicians will work to solve your A/C problems to the best of their ability. We’re here to help you get back on the road in your A4 Quattro — without all the sweat puddles!
