How to properly maintain the electrical components in my Audi?

I recently purchased a used Audi and I want to make sure that I take proper care of its electrical components. What steps should I take to ensure their longevity and avoid any potential issues?

First, it's important to regularly check the battery terminals for any corrosion or buildup. This can be cleaned with a mixture of baking soda and water. Then, make sure to inspect the fuses and replace any that may be faulty. Additionally, keeping up with routine maintenance, such as changing the spark plugs and wiring, can help prevent any electrical issues.

Another important tip is to avoid overloading your electrical system. This means not plugging in too many devices or using high-powered accessories all at once. This can put unnecessary strain on your electrical system and lead to potential malfunctions.
