Why does my Audi A6 struggle to accelerate after reaching high speeds?

I've noticed that after driving at high speeds for an extended period of time, my Audi A6 seems to struggle to accelerate when I press on the gas pedal. What could be causing this issue?

This could be a sign of a clogged fuel filter. Try replacing it to see if it improves your acceleration. If not, it may be a problem with your fuel injection system.

Another possible reason could be a malfunctioning turbocharger. If this is the case, it's important to get it checked out by a mechanic as soon as possible to prevent further damage to your engine.
