How do I make my M5 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.

Why do I get hot air from my M5 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.

What can cause an A/C system 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 M5's A/C system.

Does running the A/C in my M5 use gasoline?

Your M5’s A/C uses some power from the engine to run. So, while your air conditioning system may not directly use gasoline as a fuel source, using the A/C can indirectly affect your vehicle’s fuel efficiency.

Why does my M5 have a vinegary smell coming from the A/C?

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 M5 creates a breeding environment for microorganisms.

Why does my vehicle have to be moving for my M5’s A/C to work?

There could be issues with one or more components in the air conditioning or electrical system. Your M5 may have a faulty cooling fan or low refrigerant.

A/C Repair Service for Your BMW M5

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. Sweat soaks the driver's seat. You take a deep breath and ask yourself, “Who can fix my BMW M5 A/C?” Firestone Complete Auto Care — that’s who! We know our way around BMW vehicles, and our qualified technicians can diagnose and service the A/C system in your 2003 BMW. Steer your BMW M5 to your nearest Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 2003 BMW M5’s A/C system to evaluate what repairs are necessary (if any). This check will include an examination of system pressure, a visual inspection, and a leak test. 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 BMW M5 A/C system that can detect refrigerant fumes escaping from the system. If there's a leak, we'll find it and fix it.

M5 A/C Recharge

Let's say we repair your 2003 BMW M5 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 use BMW’s specifications to evacuate the system. The A/C system is recharged 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. Our technicians know how to keep your A/C in tip-top shape with 2003 BMW M5 A/C recharges.

Troubleshooting BMW M5 A/C Problems

Warm air isn't the only BMW M5 A/C problem you may 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. An A/C system that starts off blowing cold air but then turns warm may suggest a leak, a blown fuse, or a damaged compressor clutch. And smelly A/C in a 2003 BMW M5? 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. Don’t sweat it — we’re here to help you chill out again in your M5.
