How can I make my 740i xDrive air conditioner 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 740i xDrive 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?

To put it simply, age and moisture are some of the main causes of leaks in your A/C. Over time, rubber gaskets and seals can wear out, which pushes much-needed refrigerant out of your 740i xDrive’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.

Does running the A/C in my 740i xDrive use gasoline?

Your 740i xDrive’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 740i xDrive 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 740i xDrive creates a breeding environment for microorganisms.

Why does my vehicle have to be moving for my 740i xDrive’s A/C to work?

Damaged or worn components in your 740i xDrive’s electrical or air conditioning system can cause the A/C to only work when the car is moving. You may be dealing with low coolant or a faulty cooling fan.

In this A/C performance inspection, we’ll check out the current condition of your 2018 BMW 740i xDrive A/C system to see if repair work is required. This check will include an examination of system pressure, a visual inspection, and a leak test. 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" is a machine that's run along parts of your BMW 740i xDrive A/C system that can detect any refrigerant fumes that might be leaking out from the system.

740i xDrive A/C Recharge

While your 2018 BMW 740i xDrive’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 use BMW’s specifications to evacuate the system. To finish, we’ll add new refrigerant to recharge the A/C system, and once we’ve done a final test on the system ourselves, 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 2018 BMW 740i xDrive A/C recharges.

Troubleshooting BMW 740i xDrive A/C Problems

You may think warm air is the only potential BMW 740i xDrive A/C problem you’ll have, but you may notice other issues, too. 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 2018 BMW 740i xDrive? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. Technicians at Firestone Complete Auto Care are ready to help you address your A/C problems. So, chill out. We're here to help you get the blast back in your 740i xDrive’s A/C!
