The array of lights on your Audi A4 dashboard can seem daunting. While some simply indicate an active feature, others warn of potential issues requiring immediate attention. Ignoring these illuminated symbols could lead to significant problems down the road. This guide will help you understand some of the most common dashboard lights in your Audi A4.
Common Audi A4 Dashboard Warning Lights
Brake System Warning Light
A circular icon containing an exclamation point, often accompanied by the illuminated “BRAKE” text, signals a malfunction within your brake system. This could indicate low brake fluid, worn brake pads, or a more serious issue. A message may appear on your dashboard display providing additional information. If this light illuminates, it’s crucial to visit a qualified Audi service center immediately.
Brake Pad Wear Indicator
This light, appearing as a circle with lines on either side or the text “BRAKE WEAR,” indicates your brake pads have reached their wear limit and require replacement. Continued driving with worn brake pads compromises your braking performance and safety. Schedule a brake pad replacement at an Audi service center as soon as possible.
Central Indicator Light
Represented by a triangle with an exclamation point inside, this light signifies a general warning. When illuminated, check the instrument cluster display for a corresponding message detailing the specific issue. This light often accompanies other warning lights, providing context for the problem.
Coolant System Warning Light
An icon resembling a thermometer positioned above wavy lines indicates a potential problem with your cooling system. This could mean low coolant levels or an excessively high engine temperature. Consult your owner’s manual for specific instructions, but avoid driving if this light appears. Continued driving with an overheated engine can cause severe damage.
Tire Pressure Monitoring System (TPMS) Light
This light, shaped like a flat tire with an exclamation point, indicates low tire pressure in one or more tires. Underinflated tires negatively impact fuel efficiency, tire lifespan, handling, and braking performance. Check your tire pressure immediately and inflate to the recommended levels. Consistent low pressure could signify a leak requiring professional repair.
Consulting Your Owner’s Manual
While this guide covers common Audi A4 dashboard lights, your owner’s manual provides a comprehensive explanation of all warning and indicator lights specific to your model year. Always refer to your owner’s manual for the most accurate information. If you’re uncertain about the meaning of a particular light or encounter persistent warning lights, seek professional assistance at an authorized Audi service center.
