What are the common issues in Audi cars with speed control?

Recently, my Audi car has been having some issues with maintaining speed control. It either accelerates or decelerates at random without me pressing on the pedals. What could be the possible causes for this and what should I do?

One common issue with Audi cars and speed control is a malfunctioning throttle body. This can cause erratic behavior in your car's acceleration and deceleration. It's important to have this checked and replaced if necessary by a qualified mechanic.

Another possible issue could be a faulty speed sensor. This can cause your car to have trouble maintaining a steady speed, as it relies on the sensor to accurately measure your car's speed. Again, it's best to have this checked and replaced by a professional.

Sometimes, the issue could also be related to a dirty or clogged fuel system. Make sure to regularly clean and replace your fuel filter to avoid any potential issues with speed control.
