How to Troubleshoot a 2000 Audi A8

1. Listen for squealing during braking. The metallic scraping or squealing during braking is due to the A8s brake pad wear indicator. This means that your brake pad has reached the end of its service life and needs to be replaced.
2. Check to see if there is vibration while traveling at highway speeds. Your tires may be over or under-inflated. This is a simple problem to correct and requires a trip to the gas station. Most gas stations have an air pump. Set the pump dial to the correct tire pressure for the tires you have on the vehicle and correct the pressure.
3. Check to see if the engine rotates but will not start. This can be a symptom of an empty fuel tank. Hey, it happens to the best of us. If you let the fuel tank run dry trying to make it to a gas station it can be quite embarrassing. But, the fix is easy. Another potential problem could be that one of the battery cables is loose or is not making a good connection. This can happen if corrosion builds up on the terminals of the battery. It happens to nearly all types of batteries and the A8s battery is no exception. You can clean the battery terminal by pouring some baking soda on the terminals and scrubbing them with a wire brush.
4. Listen for clicking noises when you turn left or right. This happens due to a failing CV joint. This is common as the car ages because CV joints do eventually wear out. The protective boot rips, axle grease leaks out and the joint begins to grind. At this point, youll need to replace the entire CV shaft. This can be done at any good mechanics shop.
