How can I make my S4 air conditioner 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 do I get hot air from my S4 A/C?

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.

Does the A/C in my S4 rely on gas?

S4 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 S4’s A/C smells like vinegar! What can cause that?

It’s easy for moisture to accumulate in your car’s air conditioning system, which can cause microorganisms like bacteria to grow. In turn, this bacteria growth can cause the A/C in your S4 to produce a vinegary odor.

Why does my vehicle have to be moving for my S4’s A/C to work?

There could be issues with one or more components in the air conditioning or electrical system. Your S4 may have a faulty cooling fan or low refrigerant.

A/C Service for Audi S4

Few things are worse than a broken car air conditioner on a hot summer day. Your steering wheel feels like lava. Your skin sticks to the driver’s seat. “Who can fix my Audi S4 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 technicians are qualified to diagnose and repair 2011 Audi S4 A/C systems. Steer your Audi S4 to your nearest Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 2011 Audi S4’s A/C system to evaluate what repairs are necessary (if any). This check includes a visual inspection, performance test, and pressure and leak test. If we suspect a leak, we’ll send a U/V dye through your A/C system or use a “sniffer” to find the leak. 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 identify points where refrigerant fumes could be escaping the system. If your A/C system has a leak, we’ll find and repair it.

S4 A/C Recharge

Let's say we repair your 2011 Audi S4 A/C system. We will also perform 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. 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 good to go. Our technicians are trained to efficiently perform 2011 Audi S4 A/C recharges.

Other Audi S4 A/C Problems

Warm air isn't the only Audi S4 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. If you notice that your A/C system’s air is cold at first, then quickly goes warm, this can mean there’s a malfunctioning compressor clutch, a leak, or a blown fuse. And smelly A/C in a 2011 Audi S4? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Our trained technicians will do what they can to solve your A/C problems. We’re here to help you get back on the road in your S4 — without all the sweat puddles!
