Why does my Audi A2 lose power at high speeds?

I've noticed that when I'm driving my Audi A2 on the highway at high speeds, it seems to lose power and struggle to maintain speed. What could be causing this issue?

It sounds like your car may have a clogged fuel filter. This can limit the amount of fuel reaching the engine and cause a loss of power at high speeds. I would recommend taking your car to a mechanic to have the fuel filter checked and possibly replaced.

Another potential issue could be a failing catalytic converter. This can cause similar symptoms as a clogged fuel filter. I would suggest getting your car checked by a mechanic to see if this is the problem.
