How do I make my S4 air conditioning colder?

Here are a few quick ideas. Shut the passenger air vents and point the other vents directly toward you. Park your car in the shade and use a window sun blocker. Then visit Firestone Complete Auto Care for an A/C performance check and recharge.

What’s making my S4 A/C put out warm air?

If your car’s air conditioning isn’t blowing cold air at all (or it tries, then turns warm), you could have a clogged expansion valve, a faulty compressor clutch, a leak, or a malfunctioning fuse in the system.

How does my A/C system get a leak?

A/C system leaks are often due to a combination of age and moisture. Rubber seals and gaskets naturally degrade over time, allowing refrigerant to exit and moisture to enter your S4's A/C system.

Is my S4 A/C powered by gas?

While your vehicle’s A/C system doesn’t directly use fuel, it does draw power from the engine, which can impact the fuel consumption of your S4.

What can cause the A/C in my S4 to smell like vinegar?

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 S4 creates a breeding environment for microorganisms.

What is causing my S4’s A/C to only work when the car is in motion?

If your A/C only works when the vehicle is moving, there could be a problem with part of your S4’s A/C or electrical system. Potential issues include low coolant or a faulty cooling fan.

Audi S4 A/C Repair

When you get in the car on a hot summer day, the last thing you want is a broken air conditioner. Your steering wheel feels like lava. That puddle in the driver’s seat? Sweat. Ugh. You wipe your brow and wonder, "Who can fix the A/C in my Audi S4?" Firestone Complete Auto Care — that’s who! We know Audi vehicles, and our technicians are qualified to diagnose and repair 2019 Audi S4 A/C systems. Come to your local Firestone Complete Auto Care in your Audi S4

During this initial A/C performance check, we’ll look at the state of your 2019 Audi S4’s A/C system to evaluate what repairs are necessary (if any). We’ll test overall system performance, check for any leaks, and measure the system pressure. If we think there might be a leak, we'll run a special U/V dye through the system or use a "sniffer." A “sniffer” isn’t a technician with a good nose! It’s a machine that’s used on different parts of your Audi S4 A/C system to detect refrigerant fumes escaping from the system. If your system has a leak, we can get it fixed.

Recharge the A/C in Your S4

While your 2019 Audi S4’s air conditioner is being serviced, we’ll also do an A/C evacuation and recharge. To do this, one of our technicians will remove the refrigerant in your A/C system (if there is even any left to remove). Next, they will evacuate the system according to Audi's recommendations. To finish, we’ll add new refrigerant to recharge the A/C system, and once the technician tests the cool blast for themselves, you’re all set. Our technicians are trained to efficiently perform 2019 Audi S4 A/C recharges.

Troubleshooting Audi S4 A/C Problems

Hot air is a common Audi S4 A/C problem, but it’s not the only issue you might encounter. Another common A/C problem is weak airflow, which could mean you have a compromised seal, mildew or mold buildup, a loose or damaged hose, or a ventilation fan that needs to be replaced. If your A/C system blows cold air first but then it turns warm, this may be due to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak. Are you breathing in some “interesting” new odors in your 2019 Audi S4? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Technicians at Firestone Complete Auto Care are ready to help you address your A/C problems. Don’t sweat it — we’re here to help you chill out again in your S4.
