Audi parking brake warning light being on can be solved by: 1. Check if the handbrake lever is fully released. If not, the handbrake switch underneath may remain in the on position, or the handbrake may not be pressed to the switch position; 2. Check if there is a lack of brake fluid, and replenish it promptly if necessary; 3. Use a computer diagnostic tool at a 4S shop to detect the issue, perform repairs based on the fault code, and then reset the warning light. Taking the 2020 Audi A6 as an example, it belongs to the mid-to-large-sized car category, with body dimensions of: length 5038mm, width 1886mm, height 1475mm, wheelbase 3024mm, fuel tank capacity 73l, and curb weight 1800kg.
When the parking brake malfunction light illuminates in my Audi, I immediately pull over to ensure safety, as it may indicate an issue with the electronic parking brake system. Common causes include insufficient brake fluid, dirty sensors, or circuit malfunctions. I've tried opening the hood to check if the brake fluid reservoir level is above the minimum line, and if low, I add brake fluid that meets specifications. I also restart the system: turning off the engine, waiting a few minutes, and then restarting to see if the light goes off. If this doesn't work, never risk driving; I drive straight to the 4S dealership to use professional diagnostic tools to check for fault codes. They found it was a control module software bug, which was resolved after an update. Regular maintenance can prevent such issues, especially checking electronic systems before rainy days or long-distance drives is crucial.
