The steps go as so:
1) Moderate braking + Regen 100%
2) Regen diminishes and kicks out after a minimum speed
3) Regen kicks in 2 bars for a split second
4) Regen quickly kicks out again
5) Auto-stop engages
6) Brakes alone bring car to complete stop.
This doesn't happen all the time, but I suspect it has to do with the algorithms controlling the amount of regeneration. I am braking with constant pressure, but I think the computer gets confused and tries to apply more regen right before I stop, then it hits the limiting condition that regen cannot be applied below a certain minimum speed, so it kicks out the regen again.
Whatever the case, I want to know if anybody else experiences this kind of "regen lurching" when coming to a stop in an 06 HCH, or your thoughts as to why it happens and how to stop it from happening. Thanks so much!

Here's a theory. Keep in mind that I don't own a HCH, so take it for what it's worth.
As you decelerate you're using regen to assist in braking. Then you reach a speed at which not enough electricity can be generated to make regen worthwhile, so it shuts off. Then you slow down further, reaching the point of ICE auto stop. Before shutting off the ICE, the electric motor is re-engaged so that you won't be coasting in neutral. At that moment you get a bit of regen. The ICE is shut off after a couple of seconds, at which point you've lost your source of regen energy - no more regen.
