+1 this is most likely what you are looking at. Pics would help to be sure but if it is, moving it forward shouldn't be an issue. I would try to keep it centered to where it is currently though. I'm not sure if moving it towards one side of the car or the other would effect the reading. Basically this is what triggers the traction if it detects too much lateral movement. (Regardless if traction is turned off or not) I know somebody has disconnected it before so they could do donuts without triggering the traction control but not sure if that would also cause a BAS/ESP light.
