I had to "reset" mine. I read about the following procedure somewhere on here and decided to try it. As far as I can tell it helped, but hill assist is still sometimes very annoying. Maybe this winter I'll replace the module to get rid of it completely. But at any rate, here's the procedure I followed to "reset" the torque sensor to make the HSA function better.

1. Find an empty parking lot with an incline steep enough to cause the HSA to engage (doesn't take much).

2. Come to a stop facing uphill.

3. Depress the clutch.

4. Put it in 1st gear.

5. Remove your foot from the brake and "blip" the throttle to at least 4k RPM while the HSA is holding you. (You have to be quick.)

This is supposed to reset a torque sensor somewhere (from what I read on here). All I can say is, before I did this, my hill start assist WOULD NOT release before 2sec had passed. After doing this, it releases as the clutch starts to grab, but it still seems a little grabbier than it should be. Just my 2 cents.
