Mild Thump Under Right Foot
Often, while gently pulling away from a stop, and typically right after I’ve started driving, I feel and hear a double “thump.” The feel is pretty mild, but you wouldn’t miss it. Kind of like a light tap with a mallet. It usually feels like it is right under the accelerator, but always somewhere under the area covered by the floor mat, let’s say.
With that lousy description, any guesses what I’m hearing and feeling? I’m thinking it is something engaging, or disengaging, but that’s a guess. Any insights are welcome.

It doesn't happen in my two day old RS3, FWIW.

My B8 A4 does exactly the same thing.

What exactly is it checking though and why don't other cars check it?
