What are the recommended maintenance procedures for my Audi's engine?

I just purchased a used Audi and want to make sure I am taking proper care of the engine. Any advice on what specific maintenance tasks I should be performing regularly?

First and foremost, follow the manufacturer's recommended maintenance schedule for your specific Audi model. This will ensure that you are covering all necessary tasks to keep your engine running smoothly. Additionally, make sure to regularly check and change your oil and oil filter, as well as inspecting other fluids such as coolant and brake fluid. It's also important to keep an eye on the condition of your belts and hoses, as these can wear out over time and should be replaced if showing signs of damage or wear. And lastly, don't forget about regular tune-ups to keep your engine performing at its best!
