What causes the Audi R8 to have a stiff clutch pedal?

I have noticed that my Audi R8's clutch pedal is very stiff, almost too hard to push down. What could be causing this issue and how can I fix it?

One common cause of a stiff clutch pedal in the Audi R8 is a faulty clutch master cylinder. This component can wear out over time and cause the pedal to feel stiff and difficult to operate. It is recommended to have this component checked and possibly replaced by a certified mechanic.

Another possible cause of a stiff clutch pedal is low levels of hydraulic fluid. Check your car's fluid levels and top off if necessary. If the levels continue to decrease, it could be a sign of a leak in the system. Have a professional inspect and repair any leaks to ensure proper operation of the clutch.
