If you drive an Audi, you’ve likely noticed how advanced and informative its dashboard is. From engine performance to safety warnings, your Audi's dashboard lights are designed to keep you informed at all times. But with so many different symbols and colors, it can be easy to overlook or misunderstand what they actually mean.
Understanding what your dashboard is trying to tell you is crucial to maintaining your car's good condition and avoiding costly repairs. Let’s break down some of the most common Audi dashboard lights, what they mean, and what actions you should take when they appear.
Red Warning Lights: Immediate Attention Required
Red dashboard lights in your Audi are never something to ignore. These alerts typically indicate a serious issue or a critical system failure that could affect your safety or your car's performance.
Brake Warning Light
If you see the word “BRAKE” or an exclamation point inside a circle, it could mean your parking brake is on, your brake fluid is low, or there’s a problem with the braking system. Check your parking brake first, and if the light stays on, have the brakes inspected right away.
Engine Overheating Light
This looks like a thermometer over wavy lines. It signals that your engine is getting too hot. Pull over safely, turn off the engine, and wait for it to cool before checking the coolant level. Driving with an overheating engine can cause major damage.
Oil Pressure Light
A red oil can symbol warns that oil pressure is dangerously low. Stop the engine immediately and check your oil level. Continuing to drive with low oil pressure can severely damage the engine.
Amber or Yellow Lights: Caution and Prompt Service Needed
Amber or yellow lights aren’t as urgent as red ones, but they still require attention. They usually indicate a system that isn’t working properly or needs inspection soon.
Check Engine Light
A small engine-shaped symbol can come on for many reasons, from a loose gas cap to a misfiring cylinder. If the light is steady, schedule service soon. If it’s flashing, the issue is more serious and needs immediate attention.
Tire Pressure Monitoring System (TPMS)
This light looks like a horseshoe with an exclamation point. It means one or more tires may be underinflated. Check your tire pressure and inflate to the recommended PSI listed on the driver’s side door.
Electronic Stability Control (ESC)
If this light stays on, it may mean that your Audi’s traction control system isn’t working properly. This system helps maintain stability in poor driving conditions, so it’s best to have it inspected.
Green and Blue Lights: Information or System Status
These lights are typically informational. They let you know that a system is active, like cruise control or high beams.
- High Beam Indicator: A blue light shaped like a headlamp with horizontal lines signals your high beams are on.
- Turn Signals: Green arrows indicate that your left or right turn signals are activated. If they’re blinking faster than usual, a bulb might be out.
- Cruise Control: A green icon may appear when cruise control is active. It’s nothing to worry about, but you should know how to deactivate it when necessary.
Common Misunderstood Symbols
Some Audi dashboard icons can be confusing. Here are a few that drivers often misinterpret:
- AdBlue Warning Light: Found in diesel models, this light reminds you to refill the AdBlue fluid that helps reduce emissions. Ignoring it can eventually prevent your car from starting.
- Start-Stop System Light: This may appear when your engine automatically shuts off at a red light and restarts when you take your foot off the brake. If the light is yellow or red, the system may need service.
- Key Not Detected: This alert appears if your Audi’s key fob battery is low or not in range. Without the key, you won’t be able to start the car.
What to Do When a Light Comes On
If any dashboard light comes on while you’re driving, take a moment to assess the situation. Red lights mean you should pull over safely and stop driving if necessary. Yellow lights mean it’s safe to continue driving for now, but you should schedule service soon. Green or blue lights are typically status indicators, but it’s still good to know what they mean.
Your Audi’s owner’s manual has a complete list of dashboard symbols and what they mean. Still, it’s always smart to have a trusted technician run a diagnostic scan if a warning light comes on and you’re unsure why.
