Understanding dashboard warning lights in your Audi A6 is essential for safe driving, as they alert you to potential issues that could lead to breakdowns or accidents.
Recognizing these lights helps with timely maintenance, preventing costly repairs and ensuring your vehicle runs smoothly. Always consult your owner’s manual or a professional mechanic for specific advice.
Quick Navigation
Red Warning Lights (Stop Immediately)
These lights signal serious problems that require you to pull over safely right away to avoid damage or danger.
Brake System
This light means there’s a fault in the brakes, like low fluid or system failure. Stop driving, check fluid levels if possible, and call for roadside help.
Engine Oil Pressure
Low oil pressure could cause engine damage from lack of lubrication. Pull over, turn off the engine, check oil level, and add if needed; seek a mechanic if it persists.
Coolant Temperature
The engine is overheating, possibly due to low coolant or a leak. Stop immediately, let it cool, check the coolant, and get professional help to avoid engine failure.
Battery/Alternator
This indicates a charging system issue, like a failing battery or alternator. Stop soon, turn off extras like AC, and have it checked to prevent stranding.
Transmission
A problem in the transmission, such as overheating or fluid issues. Stop driving, avoid shifting gears, and contact a service center for inspection.
Airbag System
The airbags may not deploy in a crash due to a fault. Pull over and have the system diagnosed immediately for safety.

Door Ajar
A door isn’t fully closed, which could open while driving. Pull over, check all doors, and secure them properly.
AdBlue Urgent
AdBlue fluid is critically low in diesel models, risking engine shutdown. Stop and refill AdBlue immediately or visit a mechanic.
Brake Fluid Low
Brake fluid is too low, affecting stopping power. Stop, check levels, top up if safe, and seek repairs to restore braking.
Engine Overheating
Similar to coolant but focused on extreme heat. Stop, cool the engine, and inspect for causes like leaks before proceeding.
