What Audi Remote Start Does

Remote start on an Audi lets you start your engine from outside the vehicle using your key fob or a smartphone app, depending on your model year and trim level. When you press the remote start button, the engine turns on and the climate control begins warming or cooling the cabin — all before you get in the car.

Not every Audi comes with this feature. Remote start is typically available on newer models (2016 and later) and is often bundled with higher trim levels or purchased as an add-on package. If you own an older Audi or a base model, your vehicle may not have the hardware to support it, though aftermarket remote start systems exist as an alternative.

The feature works within a limited range — usually between 300 and 1,000 feet depending on your model and local radio interference. The engine will run for a set time (often 10 to 15 minutes) before shutting off automatically if you don't get in and press the brake pedal.

Key Takeaways

  • Audi remote start is built into the key fob on newer models and controlled through the MMI infotainment system or the myAudi app on compatible vehicles.
  • The feature only works when your doors are locked and the parking brake is engaged, as a safety measure to prevent unintended movement.
  • Remote start range varies by model but typically reaches 300 to 1,000 feet, and the engine shuts off automatically after 10 to 15 minutes.
  • If your Audi doesn't have factory remote start, you can explore aftermarket options, though installation and compatibility depend on your specific model year.

How to Use Remote Start on Your Key Fob

On Audis equipped with factory remote start, the key fob has a dedicated button — usually marked with an engine symbol or labeled "Start." Hold this button for two to three seconds until you see the lights flash or hear the horn sound once, confirming the engine has started.

Your Audi will only respond to remote start if certain safety conditions are met. The doors must be locked, the parking brake must be engaged, and the transmission must be in Park (for automatic) or Neutral (for manual). If any of these conditions aren't met, the remote start command will fail silently — the fob won't give you feedback that something is wrong.

Once the engine starts, the climate control activates automatically. In winter, the heater runs; in summer, the air conditioning kicks in. The engine idles at a normal RPM and will continue running until you either press the brake pedal to take over driving, or the timer expires and the engine shuts itself off.

Using Remote Start Through the myAudi App

Newer Audi models (typically 2020 and later with the MMI Navigation Plus system) support remote start through the myAudi mobile app, available on iOS and Android. This method gives you remote start capability from anywhere with a cellular signal, not just within radio range of your car.

To use the app, open myAudi, select your vehicle, and look for the "Climate" or "Remote Start" option on the main screen. Tap the start button and confirm your action — most apps require a second confirmation for security. The engine will start and the climate system will begin conditioning the cabin.

App-based remote start has the same safety requirements as key fob remote start: locked doors, engaged parking brake, and transmission in Park. If your vehicle doesn't meet these conditions, the app will either refuse the command or show an error message explaining why the start failed.

When Remote Start Won't Work

Remote start will fail if the parking brake isn't fully engaged, if a door is unlocked, or if the transmission isn't in Park. Some Audis also disable remote start if the fuel tank is too low or if there's a fault detected in the engine management system. Check your owner's manual for your specific model's safety cutoffs.

Cold weather can also affect remote start performance. In very cold climates, the engine may take longer to turn over, and some Audis have a built-in delay to allow the engine to warm up before the climate system runs at full power. This is normal and protects the engine from thermal shock.

If remote start has stopped working on a previously functioning vehicle, the most common causes are a dead key fob battery, a faulty fob button, or a disconnected battery in the car itself. Try replacing the fob battery first — most Audi key fobs use CR2032 or similar coin-cell batteries available at any pharmacy or electronics store.

Aftermarket Remote Start for Older Audis

If your Audi doesn't have factory remote start, aftermarket systems are available from companies like Viper, Compustar, and others. These systems require professional installation and involve running wires through your dashboard, integrating with your ignition system, and programming a new remote control.

Aftermarket remote start costs vary widely — typically between $300 and $800 for parts and labor — and compatibility depends heavily on your specific model year and transmission type. Manual transmissions are more difficult to retrofit and some shops won't install remote start on them due to safety concerns.

Before purchasing an aftermarket system, contact a local car audio or security shop with experience on Audis. They can tell you whether remote start is practical for your model and what the actual cost will be. Some shops offer warranties on installation, which is worth asking about.

Remote Start and Your Vehicle's Warranty

Factory remote start on newer Audis is covered under your standard powertrain and electrical warranty, which typically lasts four years or 50,000 miles. If the remote start feature fails during this period and the failure is not due to physical damage or misuse, Audi will repair or replace it at no cost.

Aftermarket remote start systems are not covered by Audi's warranty. The shop that installs the system usually provides a separate warranty on their work and parts, typically one to three years. Read the warranty terms carefully — some shops exclude damage from accidents or water intrusion.

Frequently Asked Questions

Can I remote start my Audi if the windows are down?

No. Remote start requires all doors to be locked, which means all windows must be closed. If a window is down, the door lock won't engage fully, and the remote start command will fail. This is a safety feature to prevent the car from running unattended with an open window.

How long does the engine stay running after remote start?

The engine typically runs for 10 to 15 minutes before shutting off automatically. The exact time depends on your model year and settings in the MMI menu. You can stop the engine early by pressing the brake pedal and shifting into Drive, or by pressing the remote start button again.

Does remote start drain my battery?

Remote start uses a small amount of battery power, but not enough to drain a healthy battery in normal use. If you use remote start multiple times a day in very cold weather, the cumulative drain is noticeable but not dangerous. If your battery is already weak, frequent remote start use may speed up the time until it needs replacement.

Will remote start work if my car is in the garage?

Key fob remote start works through radio signals, which can penetrate most garage walls, though range may be reduced. App-based remote start works anywhere with cellular signal, including inside a garage. However, never remote start your car in a closed garage — the exhaust will accumulate and create a carbon monoxide hazard.

What's the difference between remote start and remote climate control?

Remote climate control (available on some newer Audis) runs the air conditioning or heating without starting the engine. It uses battery power to run the climate compressor and fan. Remote start actually starts the engine, which is more powerful but uses more energy. Some Audis offer both features separately.
