Problems:

1. front rises on take off
2. front rises at speed and car does not feel grounded
3. car feels like jelly and floats when changing lanes or direction at speed
4. Service Ride Control is displayed on DIC

Videos below show rebound - well as best a video phone can :laughing:

Is it time for coilovers..... PFADT??

Thats definitely alot of motion. How many miles are on the car?

Your sig says you are slammed. That's your problem. If you are really slammed, the shocks now are too long. They don't have any travel, so the sensors for the F55 system are giving strange readings, hence your trouble code and the floating, as your shocks are no longer working.

Also, if in lowering your car, you dropped the rear enough to lose the 1 inch or so of rake the car came with, you have now lost a lot of the designed in downforce at speed. Without the rake, the car becomes an airfoil (actually,it still is when stock, but with a negative angle of attack.) Get up to speed, and your car is making lift, giving you that light, floating feeling.

The F55 was not designed to be slammed, so you need to either get the shorter than stock Bilstiens or go to a coilover.

Wow, that's not very many for that kind of travel.:lookinup:
