Why is the accelerator pedal on my Audi A6 feeling stiff?

I recently noticed that the accelerator pedal on my Audi A6 has become quite stiff and it's making it difficult to accelerate smoothly. I've checked the cables and nothing seems to be stuck. What could be causing this issue?

It's likely that your accelerator pedal is experiencing wear and tear, especially if your car is older. This can cause it to become stiff. I recommend taking it to a mechanic and having them inspect it and potentially replace it if needed.
