What does the car's EPC light mean?

I noticed the EPC light on the dashboard of my Audi A4, what does it indicate and how do I fix it?

The EPC light in your Audi A4 stands for Electronic Power Control. It indicates a problem with the car's throttle system, which can cause a decrease in power and acceleration. It's best to take your car to a certified mechanic for diagnosis and repair.

I've had this issue before with my Audi, and it turned out to be a damaged accelerator pedal sensor. It's a common problem in these cars and can be easily replaced by a professional.
