Is it serious if the Audi A6L scrapes its undercarriage while driving?

If the scraped area has become deformed, it should undergo panel beating and repainting. You can go to a 4S shop or repair shop for panel beating and repainting. Additionally, it is advisable to apply undercarriage coating to the vehicle's undercarriage. The purpose of undercarriage coating is to enhance driving safety by securely sealing the screws on the car's undercarriage, preventing them from loosening during driving. It adheres tightly to the vehicle body, providing long-term rust protection for the metal. Below are some driving precautions: 1. Check the rearview mirrors: When turning or changing lanes, you must use the turn signals and decelerate. Always check the rearview mirrors before turning. Left turns mainly require checking the left rearview mirror, right turns mainly require checking the right rearview mirror, and both left and right turns require checking the interior rearview mirror. 2. Don't stare at the front of the car: When driving on a clear road, look straight ahead at about 100 meters in front, and avoid staring at the immediate front of the car. 3. Depress the clutch: Generally, when decelerating at speeds above 40 km/h, there's no need to depress the clutch first; wait until the speed drops to around 20 km/h before depressing the clutch. 4. Steering: Turn the steering wheel slowly at high speeds and quickly at low speeds.
Last time when I drove my Audi A6L over a pothole, the undercarriage got scraped, which really worried me since Audi's ground clearance isn't particularly high and is prone to impacts. Generally speaking, a minor scrape on the undercarriage might be nothing more than superficial scratches, but potential issues should still be watched out for, such as a cracked oil pan leading to oil leaks, or a deformed exhaust pipe causing noise and exhaust leakage. In severe cases, suspension components could be damaged, affecting handling. I immediately pulled over to check underneath for any oil stains or dents, and didn't notice anything obviously wrong. Later, at the dealership, the technician lifted the car for a thorough inspection and confirmed it was just the plastic underbody shield that got scratched, with no serious damage. My advice is not to panic if you scrape the undercarriage—first, visually inspect for any fluid leaks or unusual noises. If everything seems fine, remember to slow down when going over bumps during daily drives, and consider installing underbody protection during regular maintenance to prevent future issues.
