Weird Jiggle When Stopping

Unless I'm super careful about modulating the brakes, I get a very noticeable back and forth jiggle after coming to a stop. Is this due to the bagged suspension and normal? My M5 has sensitive brakes, but never a hint of jiggle.

I know when coming to a stop on a hill, it abruptly bounces back/forth when the anti-roll back engages. Nothing like the i3 which was totally unobtrusive.

Also, does anyone notice loud solenoid clicking from front engine compartment every 10 seconds or so when running climate control ?

About the only annoying thing about the car is the abrupt jiggle or brake hold when you come to a stop, especially on a slight hill. The car holds the brakes, then releases, then holds, and it's a bit jerky and unrefined.

Maybe this is something that will smooth out over time or with a software update, perhaps, that would make the friction brake hold slow and less jerky?

I took my first long drive in the car today. My previous experience had been with my wife driving, and she had never experienced brakes as sensitive and capable as these on the i4. This will be her daily and i'm confident she can tame the jiggle with some more miles under her belt. I'm very impressed with the car, but not quite ready to give up my V8.
