Why does my Audi A6 shake when accelerating at high speeds?

I've noticed that my Audi A6 starts to shake and vibrate when I accelerate at high speeds, especially on the highway. It seems to smooth out when I let off the gas or when I am driving at slower speeds. What could be causing this issue?

This shaking could be a sign of a misaligned or damaged wheel. It's important to have this checked by a professional as soon as possible to avoid any potential safety hazards.

Check the tire pressure of all four tires. If there is a significant difference in pressure, it could be causing the shaking. Make sure to inflate or replace any tires with low pressure.

One common cause of shaking in an Audi A6 is a worn out constant velocity (CV) joint. Have a mechanic inspect the CV joints and replace them if necessary.
