What causes the Audi RPM to spike when accelerating?

I've noticed that when I accelerate in my Audi, the RPM will suddenly jump up before settling back down. This doesn't happen all the time, but when it does, it's quite concerning. Is this a known issue? Is there a solution?

It's possible that this is due to a faulty throttle position sensor in your Audi. They can wear out over time and cause irregular readings, which can cause the RPM to spike. You should get this checked out by a mechanic to avoid any potential engine damage.
