How do I make my 540i xDrive 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 do I get hot air from my 540i xDrive A/C?

Maybe your A/C starts cool but then gets warm. Or maybe it never gets cold in the first place. Either way, your A/C troubles could be traced back to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak.

What can cause an A/C system 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 540i 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 540i xDrive use gasoline?

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 540i xDrive.

What can cause the A/C in my 540i xDrive to smell like vinegar?

Moisture can accumulate on your vehicle’s A/C system components, creating the perfect breeding ground for bacteria. As this bacteria grows, it can cause the air conditioning system in your 540i xDrive to have a vinegar-like smell.

Why does my 540i xDrive’s A/C only work when the car is moving?

There could be issues with one or more components in the air conditioning or electrical system. Your 540i xDrive may have a faulty cooling fan or low refrigerant.

A/C Service for BMW 540i xDrive

There’s nothing worse than cranking your car air conditioner on a hot day — and discovering it’s broken. Your steering wheel feels like it's burning your hands. That puddle in the driver’s seat? Sweat. Ugh. You wipe your brow and wonder, "Who can fix the A/C in my BMW 540i xDrive?" Easy — Firestone Complete Auto Care! We know our way around BMW vehicles, and our qualified technicians can diagnose and service the A/C system in your 2018 BMW. Bring your BMW 540i xDrive to your local Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 2018 BMW 540i xDrive’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 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" is a machine that's run along parts of your BMW 540i xDrive A/C system that can detect refrigerant fumes escaping from the system. If your system has a leak, we can get it fixed.

540i xDrive A/C Recharge

When we perform an A/C repair on your 2018 BMW 540i xDrive, we’ll also do an A/C evacuation and recharge. During this process, a technician will remove the old refrigerant from the A/C system. Then, they’ll perform an evacuation (also known as a discharge) on the entire system per BMW guidelines. The A/C system is recharged with new refrigerant and after one final test to be sure the system is cooling properly, you’re all set. We want you to be comfortable in your car, so we train our technicians to perform 2018 BMW 540i xDrive A/C recharges.

Common BMW 540i xDrive A/C Problems

You may think warm air is the only potential BMW 540i xDrive A/C problem you’ll have, but you may notice other issues, too. 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 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 2018 BMW 540i xDrive? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. 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 540i xDrive.
