Bmw e90 keeps blowing power distribution box

[Bmwlady]

I have a bmw e90. 2011. 320d. A year ago i drove over a cattle rail and it blew the power distribution on the battery terminal. It was the second 'fuse' when the plastic was removed. The car would try to start but would not. After creating a bridge over the disconnected fuse it was fine untill it burned the wire made bridge again on a gravel road. I replaced with a new one. When slightly faster over a bump then normal. Blew same place on power distribution. I 'bridged' it again. No windows. Central locking or lights was working now but car drove at least. Then i parked it under a car port. No rain but had heavy mist. After a month tried to start car it would not. If i connect the battery it burns in sparks and fire the second fuse on power distibution box intill it is disconnected. If i try to bridge it burnes my 'bridge wire'. If fuse is disconnected and battery is still on i have power on the car with no extra warning but will not start with that disconnected fuse as it apparantly runs the feul managment. Something keeps blowing my power distribution box and now it is so bad it would not allow to have it connected who can help me with a answer to this problem?

Sounds very serious.

I would try get it to an auto electrition to look/trace your wiring and not only the connections at the battery.
