What does the crossed-out bulb light on the Audi dashboard mean?

Audi's exhaust temperature is too high, and excessively high exhaust temperature can easily cause damage to the three-way catalytic converter. Below is an introduction to the car dashboard: 1. Car dashboard: The car dashboard is a device that reflects the working conditions of various vehicle systems. Common indicators include the fuel indicator, washer fluid indicator, electronic throttle indicator, front and rear fog light indicators, and warning lights. 2. Tachometer: The tachometer is generally located on the instrument panel, placed symmetrically with the speedometer. The tachometer operates based on magnetic principles, receiving pulse signals generated when the primary current in the ignition coil is interrupted. This signal is then converted into a displayable RPM value. The faster the engine speed, the more pulses the ignition coil generates, and the higher the RPM value displayed on the gauge.
I've been driving an Audi A4 for many years and am quite familiar with this dashboard bulb warning light with a cross symbol. It's actually a fault indicator, telling you that one of the exterior bulbs has burned out, such as a taillight, brake light, or headlight not functioning properly. Once this light came on during my commute home, and when I checked, it turned out the left rear taillight was out. Fortunately, it was only drizzling so I could still drive back. The risks of not fixing it promptly are significant: at night, other drivers can't see your vehicle clearly, increasing the chances of rear-end collisions or traffic tickets, and raising safety hazards. Audi's monitoring system works well, detecting these minor issues immediately. I recommend fellow drivers to visit a repair shop or dealership for a bulb check and replacement as soon as they see this warning light—it's a quick and inexpensive fix, usually costing less than 100 yuan. Don't wait until nightfall when bigger problems might arise. Developing a habit of checking your lights weekly can prevent potential issues.
